1990 Report by the Dean for Research 1


Food and fiber production as well as natural resource
protection and conservation in Florida experienced several
challenges during the 1980s as a result of natural and/or
man's intervention. The state received three major freezes
during the 1980s that significantly changed the citrus
industry in the state. The presence of pesticides (Temik,
EDB, etc.) and nitrate in groundwater as well as eutrophi-
cation of several major lakes were attributed to agricultural
production (Apopka, Okeechobee, etc.). These water
quality issues resulted in new practices and/or policies for
applying and handling pesticides as well as increased
emphasis on their review by the Environmental Protection
Agency (EPA). Also, the latter part of the decade had
insufficient rainfall; thus, increasing the need to improve
water management and increased irrigation efficiency.
The above, along with the identification of new diseases
(Citrus Canker, Peanut Stripe Virus) or new approaches to
existing diseases (Brucellosis) as well as new insect
problems, have impacted the agricultural industry and the
way it conducts business in Florida. Each of these as well
as others have significantly influenced the IFAS research
agenda. Some changes occurred abruptly in response to an
identified need, while others were more gradual and were
an attempt to anticipate a problem prior to its occurrence.
The 1990s are certain to bring further changes in the
availability and use of pesticides, fertilizer and water as well
as policies governing agricultural and natural resource
management in the state. Thus, it is important that IFAS
research programs be multifaceted and flexible to address
issues broader than those of the past. These include food
safety, enhanced compatibility of agriculture, natural
resources and the environment, enhanced profitability of
commercial aquaculture, improved efficiency and protec-
tion of soil and water resources, development of new
agricultural enterprises, improved production systems for
forestry, computerized decision support systems and
exploitation of biotechnology for Florida. A product of the
above has prompted increased emphasis in the following
four areas:
1. Alternative Pest Control Strategies
Identify Pest Resistance Genes
Integrated Pest Management
Biological Control Agents
Improved Application Technology
Management and Control Strategies
Plant and Animal Resistance through Breeding
2. Improved Animal and Plant Production Systems
Production Decision Models
New Gene Insertions Mapping and Expression
Germplasm Preservation
Marketing and Trade Issues
Sustainable Agricultural Systems
3. Food Safety and Nutrition
Development of Methods for Detection of Biological
Contaminants
Nutrient Uptake


* Human Nutrition Requirements
Improved Procedures for Handling Seafood
4. Environmental and Water Quality
Fate and Movement of Agricultural Chemicals in the
Environment
Improved Farm Management Practices
Natural Resources Management
Species Diversity
Social and Economic Issues
Ground and Surface Water Protection and
Management
The overall research programs of IFAS serve to increase
the understanding of processes occurring in food and fiber
production and natural resource sciences, to develop and
effectively use natural and human resources and to
translate new knowledge into action. The products of this
activity for the citizens of Florida are improvement in their
quality of life, their food and fiber, their resources and the
communities in which they live.
During the past year, a new building was constructed and
dedicated at the Southwest Florida Research and Educa-
tion Center at Immokalee, a Turf Facility in Gainesville
was dedicated in memory of Dr. Granville Horn, construc-
tion of new greenhouse facilities behind Fifield Hall on the
Gainesville campus were completed, construction of a new
building for the Department of Entomology and Nematol-
ogy was initiated and is due for completion in the fall of
1990. Construction has also been initiated of a new
laboratory facility at the Everglades Research and Educa-
tion Center, Belle Glade.
Research completed by the Florida Agricultural Experi-
ment Station, IFAS/University of Florida, is published in
scientific journals, bulletins, circulars, books and confer-
ence proceedings. Scientists at the Experiment Station
also participate in field days, short courses, conferences and
other public information programs to acquaint producers
and consumers with recent research findings as well as new
research directions. This Annual Report includes a brief
summary of selected research programs, a list of faculty,
publications from the previous year, title of current
research projects and a brief financial report. The Annual
Report is not intended to be a detailed description of all
research underway in IFAS, but rather to summarize
selected areas and to identify those faculty conducting that
research.

1990 Selected Research Accomplishments 3


ANIMAL SCIENCES


New Stargrasses:
Stargrasses are perennial grasses that are closely related to
bermudagrass. These grasses are important to the tropical
livestock industry for grazing, hay and silage. They
generally have no rhizomes (underground stems) but
spread rapidly by long, robust stolons (runners) which
could attain 15 to 20 feet in 30 days and develop into a
dense stand 24 inches tall in 90 days. When grazed under
a rotational system at a 4-wk frequency, grasses produce
high yields of excellent quality forage averaging 9 to 14%
crude protein and 56 to 60% digestibility. Animal
performance has been good averaging 0.9 to 1.2 pounds per
day gain with a stocking rate of three 600 lb steers per acre.
Live weight gain per acre has ranged from 525 to 720
pounds per acre. These data are far superior to the 375
pounds live weight gain per acre on bahiagrass in Central
Florida.

Energy and Protein Supplementation of
Ammoniated Tropical Grass Hay.
Feeding value for livestock of most tropical grass hay is
poor. Anhydrous ammonia treatment improves the
feeding value of poor quality hay by chemically breaking
down plant parts that restrict digestibility. Crude protein
concentration of ammoniated hay is greater than that of
nontreated hay due to the addition of nitrogen from
anhydrous ammonia, and in many cases, is greater than the
animal's crude protein requirement. However, the
increased crude protein concentration in ammoniated hay
is non-protein- nitrogen, and research suggests that young
growing cattle require true protein to maximize protein
growth. During the winter of 1988, steer calves (500 Ib)
were fed ammoniated hay plus the following supplements:
(1) no supplement, (2) 1 lb cottonseed meal/head/day, (3)
ad libitum molasses, and (4) ad libitum molasses plus 1 lb
cottonseed meal/head/day. Calves fed only ammoniated
hay gained 0.5 lb/day. This level of gain is not adequate to
develop heifers for breeding as yearlings. However it
provides a base to which supplementation programs can be
applied. Cattle fed ammoniated hay plus molasses con-
sumed 6 Ib molasses/day ($0.25) and gained .8 lb/day.
Cattle fed ammoniated hay plus 1 lb cottonseed meal
($0.15) gained 1.0 lb/day. Cattle fed ammoniated hay only
were deficient in protein, and the response to protein was
greater than the response to energy. Cattle fed ammoni-
ated hay plus molasses plus 1.0 Ib cottonseed meal gained
1.7 lb/day. This level of performance is adequate for
developing yearling heifers to breed and calve at two years
of age.

Carbohydrate Digestion by Neonatal Foals.
Progress in neonatal care of premature and stressed foals
has made nutritional support of these animals critical.
When mares' milk is not available or the foal has an
intolerance for mares milk, synthetic milk replacers are
essential. A key component of these products is the
carbohydrate fraction. A study of the ability of the
neonatal foal to digest and absorb glucose, lactose, maltose
and sucrose indicates that from birth to 5 days of age foals
have little or no ability to utilize sucrose and maltose.
Glucose was absorbed readily at days 1,3 and 5 and
resulted in a serum glucose peak at 15 to 30 minutes post
feeding. Lactose was also readily digested and resulted in a
glucose peak at 30 to 45 minutes. Results indicate that
lactose is the preferable carbohydrate for foals less than 1
week of age. If the foal is unable to utilize lactose, the best
alternative is glucose if it can be fed without disturbing the
osmotic balance of the gut.

Tenderization in Brahman crossbred cattle.
Traditionally, Brahmanand Brahman crossbred cattle have
been discriminated against by the feeding and packing
industries. A portion of this discrimination has been
attributed to lower meat quality, especially tenderness, for
carcasses with heavy Brahman influence. Previous studies
did not fairly compare Brahman crossbred cattle because
they did not take into account the fact that most of these
type cattle are larger framed and later maturing than
English crossbred cattle. This research project found that
steaks from steers with 1/2 or higher percentage Brahman
breeding were less tender than steaks from 1/4 or lower
percentage Brahman, even when slaughtered at compa-
rable slaughter end points. Percentage Brahman breeding
did not effect flavor, juiciness or incidence of off-flavor. A
postmortem aging study suggested that the observed
tenderness differences may be due to a differential response
to the aging process. If mechanisms causing this differen-
tial response of breed type to postmortem aging could be
better understood and controlled, tenderness could be
assured in not only Brahman cattle but other types of cattle
as well.

Round Bale Silage.
The protein and digestible energy levels of perennial grass
forage declines rapidly as the forage matures. Researchers
recommend that bermudagrass be cut every 4 to 5 weeks
during the summer for good quality and yield of forage.
However, frequent rains during the summer often result in
field losses after cutting or delay harvest of hay while

waiting for better weather. In either situation, the hay
quality declines. Harvesting as wet forage and ensiling is
common for crops such as corn and sorghum but not widely
used for forages such as bermudagrass. The high investment
cost of the conventional silage harvesting and storage
equipment often makes chopped silage too expensive for
smaller operations. Round bale silage using conventional
hay making equipment and storing in plastic has been
researched for the past 6 years. It is essential that air be
kept out of the forage to prevent molding and rotting. The
"stretch wrap" system of wrapping individual bales with
polyethylene film appears to be superior to individual bale
bags and long tubes. It costs approximately $20 per ton of
dry forage to prevent spoilage. It is essential that the
polyethylene be resistant to sunlight degradation and
have a low permeability to oxygen. Wilting the forage for
2 to 4 hours in good drying conditions decreased moisture
from 75% to 55%, reduced bale weight, reduced wrapping
costs, reduced losses during storage and increased dry
matter consumption and performance in cattle. The
round bale silage system makes it feasible for small produc-
ers to harvest perennial grass forages every 4 to 5 weeks by
the calendar. Hay making when the weather permits is
suggested but harvesting as round bale silage at other times
insures good quality. Harvesting high quality forage
improves cattle reproduction rate and calf weaning weight,
reduces the need for supplemental feeds and should
improve profits on many ranches.

Cumulative Production and Time Trends in
Weaning Performance of Two Lines of Angus
Cattle Selected for Different Growth Patterns.
The cumulative weaning weight produced by a cow over
her lifetime provides an efficiency estimate which com-
bines reproductive efficiency and maternal ability. This
efficiency index was compared between two lines of Angus
cattle selected for estimated high mature weight or rapid
maturing rate. Smaller, faster maturing cows had a larger
cumulative production due to a higher reproductive
efficiency which compensated for lower weaning weight of
their calves. Changes in cow weight at weaning, calf
weaning weight and pounds of calf weaned per 1000
pounds of cow were estimated over an 8-year selection
period. Of these three variables, cow weight at weaning
increased, while the other two decreased. This declining
efficiency was likely caused by reduced milk production
relative to calf weight in the large size line. Future
selection of larger cattle by this criteria should consider
increasing milk production to satisfy the calves' demand.

Trichomoniasis Impacts the Profitability of a
Beef Herd.
Trichomoniasis has emerged as a major venereal disease of
cattle over the past several years. Trichomoniasis is caused
by a protozoa called Tritrichomonas foetus. The bull is the
carrier of the disease; but he does not show signs of the
disease. However, once infected, he remains infected.
There is no treatment available. The organism is spread
from the bull to the cow at breeding. The trichomonads
multiply and become responsible for the signs observed
with this disease, early embryonic deaths, infertility,
uterine infections and occasional abortions. How dramati-
cally will the disease impact an operation and its profit-
ability? We can now use the information available about
trichomoniasis to: 1) generate computer simulation
models; 2) compare disease dynamics and outcomes; and
3) broaden our understanding of how the disease influences
a breeding herd and the subsequent calf-crop. What can
we expect of a breeding season? Herd 1 (no infected bulls)
will have 96% of the cows bred and pregnant by 63 days
into the breeding season. Herd 2 (1 infected bull) will
have 82% pregnant at 63 days and 95% after 168 days of
breeding. Herd 3 (2 infected bulls) will have only 48% of
the cows pregnant by 63 days and only 69% at 168 days.
What kind of a calf crop can we expect? Herd 1 will wean
27 calves more than Herd 2 (14% more), and 95 calves
more than Herd 3 (50% more). Calves in herd 2 will be 22
pounds (4%) lighter on average than calves in herd 1.
Herd 3 calves will be 53 pounds (10% lighter than the
non-diseased herd 1. Since the calves in herds 2 and 3 are
both fewer in number, lighter in weight, and less uniform
at the target weaning date, the revenue returned is also
reduced. Calves in Herd 2 will have gross revenues of
$3,500 less (5.1%) than Herd 1, and Herd 3 will have gross
revenues of $24,500 less (35.2%) than herd 1. That is, $16
less per calf sold in Herd 2, and $37 less per calf sold in
Herd 3. What is the average return per cow that went into
the breeding season? For Herd 2 it is $18 less, and for Herd
3, it is $123 less revenue per cow compared to the cows in
disease-free Herd 1.

Prevalence of Paratuberculosis in Cattle of
Florida.
Paratuberculosis (Johne's disease), an insidious infectious
disease of ruminants caused by Mycobacterium
paratuberculosis, occurs worldwide. It has been estimated
that 5 to 20% of cattle in the United States are infected.
Precise data of prevalence of paratuberculosis for the state
of Florida have been lacking. A survey was conducted at
the College of Veterinary Medicine from 1986 through
1987 to obtain information on the status of M. ptbc.
infection in cattle in Florida. Serum samples from 3,874
beef cattle from 392 herds and 617 dairy cattle from 60
herds were obtained and tested with an ELISA method.









1990 Selected Research Accomplishments 5


Samples from approximately 10 cattle were obtained from
each herd, representing 5 geographic regions throughout
the state of Florida and 3 herd sizes (small = 0-49 head;
medium = 50-99 head and large > 100 head). Results
revealed a prevalence of 8.6% of circulating antibodies to
M. ptbc. in beef cattle and 17.1% in dairy cattle. Calculat-
ing for the entire cattle population of the state of Florida,
it would mean that an estimated 86,000 beef cattle and
30,000 dairy cattle are infected. In beef and dairy cattle,
prevalence increased with increasing herd size. It was
concluded that detectable circulating antibodies to M.
ptbc. are widespread in Florida cattle and will cause the
producers significant annual economic losses estimated to
be $9 million annually.

Eustrongylidosis in Florida Wading Birds.
Wading bird populations have declined at an alarming rate
in southern Florida, an area where the landscape has been
historically characterized by the presence of these birds.
This decline has occurred inspite of the acquisition and
attempt at preservation of vast areas of their historic
breeding and foraging grounds. A survey to determine the
effects of diseases and parasites on the reproductive success
of wading birds found that a parasitic disease, caused by
infection with the nematode parasite Eustrongylides sp.,
may be of significance in these recent declines. Mortality
can approach 100% of nestlings in some colonies. A
technique was developed for the diagnosis of this disease in
live nestlings, and applied to many colonies in southern
Florida to determine which colonies are at risk. Sampling
of the intermediate hosts of this parasite, fish and aquatic
oligochaetes, at sites important to wading birds has led to
the discovery that localized sites in which human waste
pollution and habitat alteration have occurred may be
important in the transmission of this disease.

Resistance to Mastitis.
Although antibiotic usage has gained wide acceptance in
the food animal industry, recent concerns have been
expressed that the indiscriminate use of antibiotics may
result in populations of bacteria that are resistant to
antibiotics. These antibiotic-resistant microorganisms may
represent a potential reservoir for spread of antibiotic
resistance to the human population. Streptococcal species
isolated from dairy cows with clinical mastitis were
obtained from mastitis research workers in Florida,
Louisiana, New York, Vermont, Washington, and West
Virginia. Seventy-two streptococcal isolates were tested
for resistance to erythromycin, lincomycin,


oxytetracycline, penicillin, spectinomycin, streptomycin,
and tetracycline. None of the strains were resistant to
penicillin, but at least some of the strains were resistant to
all other antibiotics tested. Resistance to multiple antibi-
otics was observed in all streptococcal species tested.
Twenty-one (30%) isolates were tetracycline resistant
(Tcr), and were chosen for further study. Studies to
determine the specific genetic basis for tetracycline
resistance suggest that bovine streptococci may differ in
their distribution of Tet determinants, and may carry
determinants not found frequently in human isolates. If
these findings are confirmed in larger studies, it would
suggest that Tcr bovine streptococci may not act as a
reservoir of human disease or spread their Tet determinants
into human strains.

Effect of Heat Stress on Fertility in Dairy
Cattle.
Holstein heifers were superovulated utilizing a sequence of
FSH and Prostaglandin F-2alpha injections. Following the
initial onset of heat, heifers were heat stressed for a
10-hour period, cooled to normal body temperatures and
then artificially inseminated. Effect of such a heat stress,
compared to non-heat stressed control animals, on embryo
survival was evaluated at day 7 post insemination. Only
12% of embryos recovered from heat-stressed heifers were
normal compared with 68.4% of embryos from
thermoneutral treated heifers. These results indicate the
extreme sensitivity of the maturing oocyte to heat stress
and emphasize to dairy producers that cattle need to be
protected from hyperthermic conditions even before
insemination, as soon as cows are detected in heat. This
short-term exposure to elevated temperatures had major
long-term negative carry-over effects on subsequent
embryonic development. Additional studies also indicate
that 7 days of intermittent heat stress between days 1 to 7
post insemination are as detrimental to fertility as the 10-
hour exposure on the day of heat. This period of sensitiv-
ity to heat, days 0 to 7, can be partially bypassed by transfer
of good quality embryos into recipient heat stressed
lactating cows at day 7 of the estrous cycle. This use of
embryo transfer was demonstrated under commercial farm
conditions in Florida.

Effect of Bovine Growth Hormone on

in cattle". There were two main objectives. The first was
to determine whether heat stress reduced the ability of
cows to fight off disease, as measured by various test of
immune function in the mammary gland and blood. The
second objective was to test whether bovine growth
hormone (called bovine somatotropin or bST) modified
the effects of heat stress. Cows received either bST or
placebo and were maintained in either a shade barn with
evaporative cooling and forced ventilation (thermoneutral
group) or in a dry lot without access to shade (no-shade
group). Results indicated that heat stress reduced certain
aspects of immune function in the mammary gland, while
having no effect on immune function in peripheral blood.
Perhaps some of the increase in mastitis in the summer
may be due to a reduction in mammary defenses against
bacteria. While not affecting immune function, bST-
treated cows were less able to maintain body temperature
in the no-shade group than control cows. The bST
increased milk production to the same degree in both
environmental groups, however. These results emphasize
that cows treated with bST or otherwise managed to have
a high level of milk production must be maintained during
the summer so that exposure to heat stress is minimal.

IGF Action in the New Born Calf.
The insulin-like growth factors (IGF-II) are growth-
promoting proteins found at high levels in cow's colostrum
and at lower levels in later milk. The presence of these
regulatory proteins in mammary secretions has generated
significant interest with respect to their possible physi-
ological functions in the mother and neonate. Research
conducted in collaboration with Dr. H. Herbert Head,
Chul-Young Lee, Cheryl Feinstein, Frank Michel and Dale
Hissem, and funded by the State of Florida Milk Checkoff
Program has now identified important markers of IGF
action in the newborn calf. Specifically, cellular receptors
for IGF-I and IGF-II have been characterized on a number
of developing tissues including the gastrointestinal tract
(probable first site of contact with ingested IGF). Further-
more, endogenous levels of IGFs in the newborn calf were
shown to be low. Thus, maternally-derived IGFs may
contribute to the early postnatal growth of calves by
binding to tissue receptors and stimulating cellular division
and differentiation. The next aspect of this study will
evaluate the natural variation in colostral IGF levels with
respect to possible differences in calf survival and growth.

Boron's Influence on Broiler Breeder
Performance.
Boron compounds are commonly used as water treatments,
detergents, algicides, insecticides and fertilizers. Wood


shavings, commonly used as litter material in poultry
houses, may contain boron as it is often used as a wood
preservative. Poultry producers may also use boron-based
insecticides to control beetles in litter. If these insecticides
are spread directly on top of the litter, the birds often
consume large amounts of boron in a short time period.
Two experiments were conducted to study the effects on
broiler breeder performance of supplementing practical
corn-soybean meal diets with 250 ppm boron. Forty-five
male and 45 female broiler breeders were selected and
placed in individual 40 x 60 cm cages for weeks (21 to 37
weeks of age). Reagent grade boric acid furnished 0 and
250 ppm boron in the diet. Body weights were maintained
at standard recommendations by controlled feed alloca-
tion. Females fed boron had numerically lower fertility and
significantly lower hatchability in each of three fertility
trials. Males produced three times more damaged sperma-
tozoal cells compared with the control birds. If boron-
based insecticides are used in poultry houses, care must be
taken to ensure that consumption of the products in
minimal or poor performance may result.

Processors Continue to Look for More Cost
Efficient Methodologies to Remove Breast
Meat from the Broiler Carcass.
The meat can be most efficiently removed immediately
after carcass chilling; however, this often results in
toughness associated with the final cooked product. To
prevent this toughness development, carcasses are often
held for a recommended 3-6 hours before boning, resulting
in a minimum loss of approximately $1,000,000 in in-
creased drip loss, energy, storage and labor costs to a plant
averaging 300,000 birds per week. An in-line procedure
has been developed involving carcass electrical stimulation
and muscle tensioning that alleviates the toughness
problem associated with boning carcasses immediately
after chilling. Currently, the patentability of the procedure
is being investigated. Once this is accomplished, suitable
equipment can be developed.

Cooling Systems for Dairy Housing.
Heat stress causes declines in dairy milk production and
animal fertility in Florida each summer. A fan and
sprinkler cooling system has been developed that can
reduce heat stress and improve dairy production. In 1989,
a study was conducted that evaluated the effect of varying
the water flow rate in this system. The results of this study

indicate that recommended sprinkler flow rates can be
reduced by a factor of four, reducing daily water usage from
100 gallons per cow to 25 gallons per cow while maintain-

Composting and Utilization of Municipal Yard
Waste.
Municipal yard waste was banned from lined sanitary
landfills by the 1988 Florida Solid Waste Act. Research at
the University of Florida, in cooperation with the Florida
Department of Agriculture and Consumer Services, the
Florida Department of Environmental Regulation, and
with Wood Resource Recovery, a private firm, has helped
to develop methods of processing municipal yard waste
into useful products. In a county-wide demonstration
project, yard waste has been composted in three types of
systems: in-bin composting, turned window composting,
and static-pile composting. Nutrient amendments, such as
poultry manure, are also being evaluated to enhance the
composting process and to improve the quality of the end
product. Other possible products include mulch and soil
amendments. Research has also been conducted to
evaluate and demonstrate the utilization of yard wastes by
the homeowner, including composting and mulching.
The application of this research will result in increased
recycling of wastes and in lower costs to the consumer.

Factors Affecting the Efficiency of Overhead
Irrigation in Container Production.
Overhead irrigation application efficiency in container
production ranges from 10 to 78% with a median of 25%.
Several factors hypothesized to contribute to these low
efficiencies were investigated. Water reaching the media
surface was measured at two plant spacings and supplied by
two sprinkler-head types. One pittosporum and two azalea
cultivars produced in 3.8, 7.6 and 11.4 liter containers
were used as test species. The percentage of water reaching
the media surface was inversely related to the leaf area
enclosed in a cylinder the diameter of the container at a
spacing of 7.6 cm between containers, and inversely related
to the total canopy leaf area when the containers were
placed pot-to-pot. Canopy densities (LAI) were less
correlated than leaf areas. Differences between sprinkler-
head types were significant but dependent on container
spacing. Container spacing and canopy shedding of water
were determined to be the main factors associated with
the low efficiencies. This information is important when


calculating irrigation rates and in the development of new
irrigation systems.

Forest Water Quality Management.
Environmental concern about the effects of forest harvest-
ing and regeneration practices resulted in a longterm study
in pine flatwoods since 1977. The data showed much
higher ground water levels for about six years in clearcut
areas, due to reduced plant water use, but increased runoff
returned to normal within a few years. Leaving some tree
vegetation will reduce these effects. Annual suspended
sediment levels increased five-fold up to 14 mg/1 only
during the dry treatment year. This was below the 37-56
mg/1 levels during the wet pre- treatment year, which in
part were due to soil disturbance for watershed construc-
tion. These sediment changes confirmed results from
similar studies elsewhere. No real changes were found in
nitrogen and phosphorus levels, but did occur in the
potassium and calcium levels proportional to the severity
of soil disturbance. Reducing soil disturbance and leaving
protective buffer zones next to open water will reduce the
effects. This information has been used to assist with the
formulation and acceptance in Florida of the forestry Best
Management Practices to reduce non-point source water
pollution.

Response of Slash Pine to Air Pollution.
Reports in the last few decades of air pollution decreasing
forest productivity prompted the installation of a study to
determine the effect of acid rain and ozone, singly and in
combination, on the growth and physiology of slash pine
growing in native soil in north Florida. Acid rain treat-
ments were 3.3., 4.3 and 53 pH (7-to-3 ratio of sulfur to
nitrogen) and were applied weekly based on a 70 year
monthly average for the site. Ozone treatments were
charcoal-filtered (about 0.3 ambient level), ambient, twice
ambient and thrice ambient, and were applied 12 hours
every day over the course of the 2 year exposure period.
Initial response to the treatments was a growth increase in
the highest acidity rain treatment, primarily due to a
fertilizer effect. During the second year this increase has
declined as the soil pH has decreased in this treatment.
Ozone has affected tree growth as expected with the
lowest ozone treatments (charcoal-filtered and ambient)
growing better that the higher ozone treatments. Results

Slash Pine Productivity.
Slash pine forests are a major production system in Florida
and the south east Coastal Plain. During the past ten years
we have studied how environmental factors control the
productivity of slash pines. Climate, soil nutrition, and
water availability have been the focus of our research
efforts. The effect of these environmental factors on slash
pine leaf growth and physiology is of prime importance.
Foresters have traditionally concentrated on stem wood
production, and considered foliage to be constant in
"closed canopy" forests. We have found large changes in
total canopy foliage mass from year to year, and seasonally.
These variations in canopy mass can be related to climate,
and nutrition. Slash pines can be considered to be a
conservative species living in a difficult environment; we
have found low rates of photosynthesis, respiration, and
transpiration compared to other tree species, but with
higher efficiency.

INSECT AND WEED RESEARCH

Eradication of Fuller Rose Beetle on Exported
Citrus.
The Fuller rose beetle (FRB) is a major concern to citrus
growers in California and Florida who opt to ship fresh
citrus to Japan. This weevil-like pest lays its eggs beneath
the fruit calyx ("button") and the Japanese fear that eggs
on export citrus will supply the "seed" for its establishment
in Japan. Both preharvest and postharvest research has
been underway on both biological and chemical means for
control. Scientists have found that: 1) By comparison to
Florida, FRB adults are more fecund (lay more eggs) in
California and Arizona, 2) Egg-laying preference by FRB
favors the calyx of the fruit, 3) Adult FRB emergence from
soil from April though January with a peak emergence
during July. Suggested time for controlling adults in the
tree is early June, mid-July and late August, 4) Less than
1% of mature fruit harvested in December 1989 and
January 1990 from different groves had viable FRB eggs
beneath the calyx whereas about 18% of the sampled fruit
harbored nonviable eggs. Viable eggs represent adult
activity from the previous month, 5) Three fungal patho-
gens, Beauveria bassiana (AF-4), Metarhizium anisopliae and
Paeclomyces fumoso-rosea are infectious to FRB larvae in
the soil and show potential as biopesticides, 6) Two strains
of the egg parasite, Fidiobia citri, have been introduced


into Florida from Jamaica and Chile. The wasp-like
parasites are being tested as potential biological control
agents of FRB eggs, 7) Gamma radiation at 0.30 kGy has
been used to induce 100% sterility of FRB eggs, 8) The
insect growth regulator, Fenoxycarb at 100 ppm has been
100% effective as an ovicide of FRB eggs, 9) Vapor heat
treatment of fruit infested with FRB eggs at 56-C for 10
min gave 100% mortaility, and 10) Industry degreening is
effective in the removal of fruit calyxes infested with FRB
eggs.

Non-chemical Alternatives for
SubterraneanTermite Control.
Barriers composed of soil particles 1.70-2.36 mm in
diameter stopped penetration by the Formosan subterra-
nean termite, while similar barriers of particle size in 1.00-
2.36 mm diameter excluded penetration by the eastern
subterranean termite. When several size ranges were
uniformly mixed, the resultant barriers composed of
particles in the 1.18-2.80 mm size effectively shielded
penetration by both termite species. The results indicate
that this non-chemical measures may be used as a pre-
construction application for homeowners in Florida where
several subterranean termite species exist.

Seasonal Incidence of Infestation of West
Indies Mahogany by Mahogany Shoot Borer in
Florida.
The mahogany shoot borer, Hypsipyla grandella, is a major
pest of mahoganies and related timber and ornamental
trees in the tropics and southern Florida. To provide
information for estimating the best timing for control
efforts, we conducted a study of the seasonal incidence of
infestation by the mahogany shoot borer during two
growing seasons in southern Florida. We found that the
total number of actively infested terminals per month
peaked in May of each year, coinciding with the spring
leaf flush of this tree. The seasonal nature of mahogany
shoot borer attack will be exploited in developing control
strategies for this pest.

from structures or placed in protective enclosures. EPA
has mandated that more efficacious protective enclosures
be developed. Research has identified that nylon film is
highly refractive to permeation by methyl bromide and
sulfuryl fluoride. When selected refrigerated and cup-
board foods were sealed in nylon bags, no fumigant residues
were detected 6 hours after exposure, even when fumigant
rates were ten times those used to control drywood
termites. Therefore, the use of nylon polymer bags to
protect foods from exposure to fumigants will result in
decreased food losses and labor associated with structural
fumigation practices.

Pinpointing St. Louis Encephalitis Virus
Transmission in Florida.
St. Louis encephalitis virus (SLE) is an important human
disease which is transmitted by mosquitoes. The virus
periodically infects large numbers of humans and the
factors responsible for these epidemics are poorly under-
stood. Domestic chicken flocks at field sites throughout
Florida serve as an excellent model system for measuring
SLE transmission in nature. Data from sentinel flocks
indicate that SLE transmission during the autumn months
is synchronized by heavy rains (greater than two inches)
following droughts of two to three weeks. With this
information it is possible to track late summer and autumn
meteorological patterns and to predict where and when
SLE transmission will occur in sentinel chickens. Our
next challenge is to accurately forecast SLE transmission
to humans.

Exotic Mosquitoes in Florida.
In 1986 the so-called Asian tiger mosquito, Aedes
albopictus, was discovered for the first time in Florida at a
tire dump in Duval county. This mosquito has spread
rapidly in north Florida where it is now known to occur in
30 counties. However, elsewhere in the state, there have
been relatively few reports of A. albopictus infestations.
The form of A. albopictus that has invaded North America
in recent years came from the temperate zone, most likely
from Japan. Yet, recent studies have shown that some
Florida populations of A. albopictus are becoming more
adapted to conditions at lower latitudes, thus enhancing
the potential for this mosquito to spread to the rest of
Florida and possibly into the Caribbean region where it
could be a major vector of certain human pathogens. Prior
to the introduction of A. albopictus, Aedes aegypti was
generally the most common Aedes found in artificial


containers throughout Florida. Now, in certain areas,
A. albopictus is by far the dominant species in these aquatic
habitats. Immature A. albopictus may be common in
artificial and natural containers, whereas immature
A. aegypti are seldom found in natural containers, such as,
treeholes and leaf axils. The females of both species blood
feed primarily during the daytime, and since they have
rather limited flight ranges, biting activity is most pro-
nounced near larval habitats. Efforts to control container-
inhabiting Aedes with insecticides have provided only
short-term relief from these pestiferous mosquitoes. On
the other hand, the implementation of improved methods
for the storage, disposal and/or recycling of used tires and
other types of artificial containers should lead to more
effective mosquito abatement.

Cyromazine Resistance in Liriomyza trifolii
(Burgess) (Diptera: Agromyzidae).
Cyromazine, an insect growth regulator formulated as
Trigard 75WP (Ciba- Geigy) for the control of Liriomyza
spp. leafminers in celery and head lettuce, is the only
registered insecticide that can effectively control
leafminers in celery and head lettuce in Florida. Lack of
complete leafminer control in celery was experienced late
in 1989 during the use of cyromazine and could be attrib-
uted to insecticide resistance. Bioassays were conducted
on a population of leafminers originating from a problem
celery field in the Belle Glade, Florida area and compared
to a susceptible colony. Bioassays were conducted on the
same colonies to determine the possible presence of cross-
resistance to abamectin, a potential alternative for the
control leafminer. Results indicated a level of resistance
high enough to cause loss of efficacy with cyromazine.
Results also indicated no cross resistance to abamectin.
Therefore, abamectin was expected to be an effective
alternative in the control of cyromazine- resistance
L. trifolii. The results of this study were instrumental in
the granting of an emergency registration for use of
abamectin for the control of leafminer in celery in Florida

Floating Row Covers Used for Insect Control.
During the fall of 1989, a lightweight floating row cover
material was tested as a method of excluding insects, both
virus vectors, such as aphids, and direct pests such as
pickleworm, melonworm, and sweetpotato whitefly, from
zucchini squash. Plants that were not covered were
infected with mosaic viruses very early, produced little or
no fruit and suffered severe pickleworm damage. No
insects or symptoms of virus were found on squash when
first uncovered, but once covers were removed for pollina-
tion, plants became infected with mosaic viruses within
three weeks. Even when covers tore, however, few insects
attacked the plants, although bees were able to enter and
pollinate. Yields were highest in rows that were uncovered
a week or more after the beginning of flowering (up to 14
times greater than those grown without covers). In
addition to reducing losses to mosaic viruses and caterpil-
lars, the use of floating row covers also prevented leaf
silvering induced by sweetpotato whitefly. Although
covers may be too expensive to use commercially on
summer squash, their use may provide benefits when used
to protect more valuable cucurbit crops and to protect
cucurbits in the home gardens.

Avirulence Genes Specify Hosts of
Xanthomonas campestris pv. vesicatoria.
Three groups of strains were distinguished by reactions on
tomato and pepper. One group is pathogenic on tomato
only, another group is pathogenic on pepper only and the
third group is pathogenic on both tomato and pepper. To
test whether avirulence genes played a role in these
responses, genomic DNA libraries were constructed from
two strains of X.c. pv. vesicatoria. Two avirulence genes
were identified that converted normally virulent strains to
avirulence. The avirulence gene avrBsT controlled the
ability of the group pathogenic on tomato to cause hyper-
sensitivity on pepper. The avirulence gene avrBsP
controlled the ability of the group pathogenic on pepper to
cause hypersensitivity on tomato. The two avirulence
genes were characterized by restriction enzyme analysis,
Southern blot analysis, and analysis of the phenotype by
electrolyte leakage from infected tissues. Both genes were
located on plasmids in the bacterium.

Citrus Tristeza Virus (CTV) is Economically
the Most Important Citrus Virus Worldwide.
CTV is a large, rod shaped virus that is confined to the
phloem tissue of citrus plants. CTV is responsible for 2
major types of disease; stem pitting, which affects grape-
fruit and sweet orange; and quick decline, which causes a
rapid death on trees that have been grafted to sour orange
rootstock. Quick decline is presently the most devastating
CTV disease in Florida. However, most experts agree that
in the future stem pitting will be the major problem. Our
group has been involved in research on CTV from a
molecular biological standpoint with two major objectives:
to identify the genetic functions of CTV in order to better
understand its biology; and to devise methods for protect-
ing citrus trees from CTV disease. With regards to the
latter, our approach is to explore coat protein-mediated
protection, or genetically engineered protection, as a
control strategy. Previous work, primarily by Roger
Beachy's group in St. Louis, has shown that plants that
produce coat protein become resistant to attack by the
virus. In order to obtain plants that make the viral coat
protein, it is necessary to genetically transform the plant
with the viral gene. We have been working on the two
major aspects of this project; isolation and characterization
of the CTV coat protein gene; and, in collaboration with
Gloria Moore, genetic transformation of citrus plants. We
have now cloned and sequenced the coat protein gene
from the severe T36 isolate of CTV. Mary Sekiya, a
former MS student, prepared an expression of cDNA
library from the viral RNA and screened this library with
antibodies to the coat protein. Fifteen positive clones were
obtained; 5 were extensively studied. All of these clones
produced coat protein in E. coli, the cloning host. Mike
McCaffry and Sue Lawrence obtained nucleotide sequence
of a region common to all clones and identified a gene
(open reading frame) 669 bases long that codes for a
protein approximately the same size as coat protein isolated
from virus. Identification of this gene as the coat protein
gene was accomplished by comparison of amino acid
composition, by a perfect match with a peptide sequence
obtained from amino-terminal sequencing of the authentic
coat protein, and by reaction of the proteins produced in
E. coli with a monoclonal antibody against the coat
protein. The cloning and sequencing has revealed notable
aspects of CTV/citrus biology. However, our more
immediate goal is to transform citrus plants with the coat
protein gene and then test for resistance of those plants to
the virus. Primarily due to Dr. Moore's efforts, we now
have a workable method for introducing genes into citrus.

sugar value due to the disease was estimated to be $36.8
million in Florida. This estimate was based on the results
of incidence surveys, yield-loss trials, 1988-89 production
statistics, and 1987-88 sugar prices. Although genetic
resistance to the disease exists, it has not been utilized
effectively for control, because a practical means to select
for resistant cultivars has not been available. To over-
come this obstacle, a procedure to screen sugarcane
breeding lines for resistance to the disease is being
developed. The procedure is based on measuring the
extent of colonization of sugarcane stalks by the pathogen,
because this parameter was found to be inversely correlated
to the degree of resistance exhibited by different cultivars.
A serological technique was developed to measure
colonization and adapted for testing large numbers of
stalks. When the procedure was used to screen the
progeny of a number of crosses between parents differing
in resistance to the disease, the degree of resistance ranged
widely among progeny of individual crosses regardless of
the susceptibility or resistance of parents. This indicates
that substantial resistance already exists within present
breeding lines which can be used for disease control.

Biocontrol of Algal Blooms with Viruses.
Current methods for controlling algae are primarily
limited to the use of herbicides. For example, copper
sulfate remains one of the main treatments for outbreaks
of blue-green algae in many parts of the world. Unfortu-
nately the use of this and other chemical agents are often
of limited effectiveness and are accompanied by undesir-
able side effects. There is a serious need for more effective
and safe agents to control blue-green algae. Ideally it
would be desirable to have agents which are highly
specific in their effect, to minimize undesirable side effects.
In accordance with this goal we are currently involved in
a USDA funded project to evaluate the potential of using
viruses, specific to blue-green algae, to control algal
blooms which plague lakes and ponds in Florida. To date
four viruses have been found in this survey. One of these
is effective against Lyngbya. The other three viruses are
lethal to three major pelagic bloom-forming cyanobacteria
Anabaenaflos-aquae, Microcystis aeruginosa, and Anabaena
circinalis.

NATURAL RESOURCES

Citrus Irrigation with Reclaimed Municipal
Wastewater (Conserv II).
More than 7000 acres of citrus in Orange and Lake
Counties, Florida have been irrigated with treated


reclaimed municipal wastewater from Orlando since 1987.
Observation and sampling sites were established for soil
water monitoring, tree response, and leaf, fruit and soil
analyses. Sites irrigated with well water were used as
controls. Groves irrigated with reclaimed wastewater had
higher soil water contents than control groves (3.88 acre
inches vs. 3.56 acre inches in 1989). The higher soil
water content adversely influenced juice quality by
reducing both the soluble solids and acid. Controls had an
average of 5.86 pound of solids per box of fruit while
Conserv II averaged 5.68 pounds of solids. Trees irrigated
with reclaimed wastewater had a better appearance than
trees irrigated with well water. Higher leaf and soil
nitrogen, phosphorus and sodium levels were found in
groves irrigated with reclaimed wastewater. The quality of
the Conserv II water is very good and heavy metal
concentrations were low. The benefits of the use of
wastewater for irrigation are; 1) a long-term source of safe
water for citrus growers that will increase with urban
growth, 2) water is currently provided free at pressures
adequate for operation of under-tree irrigation (40 lb. per
square inch minimum), 3) construction and energy costs
of deep wells are eliminated and 4) phosphorous can be
omitted from the fertilizer program because of increase soil
and leaf phosphorous contents. Liming can also be
reduced because Converv II water is more efficient in
raising the subsoil pH than conventional liming pro-
grams. It was concluded that the use of reclaimed water for
citrus irrigation is a horticulturally sound practice.

An Evaluation of Micro-Irrigation on
Sugarcane.
A study was conducted for three seasons to evaluate the
practical and economic feasibility of using micro-irrigation
as an alternative to seepage irrigation for sugarcane. A
comparison of the two irrigation methods for sugarcane was
performed on a sandy soil. Water-table levels, soil-water
status, sugarcane yield, percent sugar, and water use were
measured. Results of the study indicated comparable
yields from the two irrigation methods, but there was a
significant reduction in water use (ratio 6:1) by the micro-
irrigation system. However, there are many practical
problems associated with the adoption of micro-irrigation
for use with sugarcane on sandy soils. Approximately 60%
of the water use by seepage irrigation can be attributed to
downward percolation and therefore was returned to
ground-water reserves.

Influence of Phosphorus Fertilization on Water
Quality and Bahiagrass.
It has been speculated that increased phosphorus in Lake
Okeechobee waters results in major algal blooms which
reduces oxygen and causes major fish kills. Evidence
suggests that phosphorus is the primary factor controlling
eutrophication of many surface waters. Leaching and
runoff of soluble phosphorus fertilizers applied to beef
cattle pastures are believed to be a source of the phospho-
rus entering the water. Evidence suggests that phosphorus
fertilization rates currently recommended can be reduced
without forage or cattle production losses. A three year
study was conducted to determine the optimum phospho-
rus fertilization rate for bahiagrass and to evaluate the
influence of phosphorus fertilization rates on surface and
ground water quality. Results show that phosphorus
fertilization can be reduced from 100 to 50 pounds of
phosphate per acre without reducing yields or quality of
bahiagrass. In addition, a beneficial effect on water quality
(50 percent reduction) was observed. As a result of this
and other studies, IFAS has revised fertilizer recommenda-
tions for pasture forages. These reductions should result in
substantial cost savings to ranchers and reduce the
phosphorus levels in surface waters.

BMP Research in the Okeechobee Basin.
The Agricultural Engineering Department has three
current research projects ($3.3 million) addressing the
problem of nutrient rich agricultural runoff entering Lake
Okeechobee. The projects are specifically addressing dairy
pasture runoff, beef pasture runoff, and drainage from the
Everglades Agricultural Area (EAA, sugar cane and
vegetables). These projects are evaluating best manage-
ment practices (BMPs) for reducing the phosphorus and
nitrogen loadings from the respective operations. The
projects are also studying fundamental transport processes
in order to extend (through computer models) the results
beyond the study areas. The work has already shown that
phosphorus fertilizer rates can be cut in half on flatwood
pastures and improved drainage management in muck soils
can significantly improve water quality. Final conclusions
will not be available until 1991.

Distribution and Status of Red-cockaded
Woodpecker Colonies at Eglin Air Force Base,
Florida.
The endangered red-cockaded woodpecker (Picoides
borealis) inhabits some of the last remaining mature pine
stands in the southeastern United States. Eglin Air Force
Base in the Florida panhandle encompasses 250,000-
300,000 acres of potential suitable habitat for these birds,
but little detailed information is available on the specific
locations and activity status of colonies of these birds on
the property. The primary objectives of this study are to
survey the pine forests for the presence of red-cockaded
woodpecker (RCW) colonies, describe the colony site,
mark the RCW cavity trees and plot them on appropriate
maps, and assess the status of each colony. The survey is
being conducted using two field crews walking parallel
transects through suitable habitat; a priority system has
been developed so that areas with the highest priorities
will be sampled first. Field research began in May 1990
and is expected to conclude in September 1992. Several
thousand acres have been surveyed; these initial surveys
have revealed substantially more RCW colonies than were
previously known for the area. Data obtained from this
study will be summarized and used in planning the future
protection strategies for this endangered species and
possible options for the future use of these military lands.

Effects of Urbanization on Avian Communities
Associated with Riparian Habitats in
Gainesville, Florida.
Breeding and wintering avian communities were studied in
both urban and undeveloped riparian forests in 1989 and
1990. Two treatments in the urban areas consisted of
narrow, 20-60m, and wide, 70-150m, naturally wooded
riparian strips. These strips were bordered by single-family
residential homes. The undeveloped area is a state park
and served as the control. All sites consisted of mesic
hardwood hammock vegetation and vegetation sampling
was completed in 1989. Preliminary analysis indicates that
all sites were similar in terms of species composition and
density of trees. The shrub component was similar in
species composition, but not density. Urban sites con-
tained a higher density of birds in both breeding and
wintering seasons than the state park. Breeding season
diversity was higher in the undeveloped forest than in the
urban areas but no difference was detected during the
winter. Northern Cardinals, Carolina Wrens, and North-
ern Parula Warblers were the most abundant birds in both
urban treatments. Hooded Warblers were the most
abundant in the undisturbed forest and did not occur in
urban areas. The proportion of individuals making up each
species was less evenly distributed in the urban areas.









1990 Selected Research Accomplishments 13


Approximately 50% of the urban community consisted of
three species while five species made up the same propor-
tion of the population in the undeveloped area during the
breeding season. The results of this study may be used to
justify growth management standards that will minimize
ecological impacts of urbanization in riparian areas.

Population Genetics of Atlantic Sturgeon
(Acipenser oxyrhynchus).
This study was initiated during FY 1990 and is being
conducted with the cooperation of the U.S. Fish and
Wildlife Service. The goal of this study is to determine
levels of genetic variation within and among remnant
populations of this threatened species. Blood samples are
being collected by personnel of the U.S. Fish and Wildlife
Service as part of a tagging and life history study of
Atlantic sturgeon in the Gulf of Mexico. To date, we
have collected blood from over 300 fish. Allozymes
detected electrophoretically are being used to determine
overall levels of genetic variation. In addition, we are
suing DNA "fingerprinting" methodologies to determine
possible levels of inbreeding and within-population genetic
variation. Sturgeon populations in the Gulf of Mexico
have gone through a major population decline as a result of
overfishing and habitat degradation. In addition, the
species has a relatively long generation time (10-20 years).
As a result, wild-caught individuals from the same
localities may be closely related sibss, cousins, etc.), and
we are using DNA fingerprinting to assess this level of
relatedness. The study is in progress, and preliminary
results are not yet available.

Fundamental Design Parameters for Artificial
Reefs.
Over $13 million will be spent by Florida on fishing reef
construction in FY 90-91, yet no design criteria exist for
these structures, assumed by the public to enhance fishery
stocks. This study manipulated interpatch distance within
replicate experimental reef plots. Commercially
harvestable stone crabs had greatest occupancy rates,
greatest average, size, and most mating activity on widely
spaced patch reefs compared to more aggregated reef
patterns. The treatment effect was consistent for abun-
dance of other common reef refusing, off-reef foraging
species (i.e., octopus, black sea and gray triggerfish).
Benthic prey densities increased with distance from reef
materials and was affected by interpatch distance within
the experimental reef system. Results, thus far, confirm the
general resource mosaic model of reef ecological function.
A multivariate experiment, with full-sized reefs and more


complex fishery assemblages, is now in its first year of
construction. Five years of study are approved to more
conclusively test this model and to develop objective reef
design criteria to achieve defined management objectives.

PLANT SCIENCES

Citrus Blight Detection.
Citrus blight is a disease of unknown cause that is respon-
sible for more than $60 million in losses annually to
Florida citrus growers. CREC scientists are attempting to
detect a pathogen or pathogen related proteins or nucleic
acids in blighted trees. Seven unique proteins that serve as
biochemical markers for citrus blight have been identified.
The proteins were found in vacuum extracts of root and
stem pieces of diseased trees. These proteins are absent in
similar preparations from healthy trees. The proteins are
referred to as blight proteins and can be used to diagnose
blight in young citrus trees. Young, healthy appearing
trees that have been graft-inoculated with roots from
blighted trees were found to contain the same proteins
found in mature trees with blight. Scientists now have an
excellent tool in the early diagnosis of citrus blight and a
key to determining its cause. Evidence that the proteins
are indeed related to citrus blight include: 1) They have
been found in all trees assayed that have symptoms of
blight and high zinc levels and low water uptake. 2) They
have never been seen in assays of healthy trees or trees
declining with CTV, root rot, or water stress. 3) They
have been detected in young (presymptomatic trees) trees
that had been graft inoculated with blighted roots. 4)
They have been detected in extracts of blighted trees from
Brazil.

Early Blight of Potatoes.
Early blight is a disease which attacks potato foliage after
blossoming. For many years the disease was believed
unimportant in northeastern Florida. Recent data has
documented losses as high as 42% associated with the
disease in unsprayed potatoes. In addition, based on rapid
defoliation and other factors, it is believed that an unusu-
ally aggressive strain of the pathogen exists in Florida
which may account for the large losses in yield during some
years. This disease is effectively controlled with properly
applied fungicides including Chlorothalonil and
iprodione.

Corky Ringspot Disease.
Potato corky ringspot disease is important in northeastern
Florida potato production. This disease is caused by a virus
which is transmitted to potato tubers by stubby root
nematodes. Nematodes are microscopic roundworms
which inhabit the soil and parasitize the roots of plants.
Resistance to corky ringspot in several varieties of potato
was reaffirmed in 1990. Varieties Superior, Late Superior,
Oceania, and Hudson showed outstanding resistance under
intense disease pressure. Temik, which is the most
effective chemical control for corky ringspot, will be
unavailable to growers during 1991 so resistant cultivars
will play a more important role in managing the disease.
These cultivars will offer growers an alternative to Temik.

Unique Chromosome Makeup for Florida
Strains of the Citrus Post Bloom Fruit Drop
Pathogen.
The fungus Colletotrichum gloeosporioides causes the disease
post bloom fruit drop in citrus. To test for genetic varia-
tion in the pathogen, the chromosome banding patterns of
several strains of the fungus were examined using a new
technique called pulsed field electrophoresis. Type
cultures of the fungus were examined as well as strains
isolated from both lime and sweet orange from various
parts of Florida, Belize and Mexico. All strains from
Florida contained chromosomes that were 3 million base
pairs (3.0 Mb) in size and most also contained chromo-
somes between 0.64 and 1.6 Mb. Type cultures and strains
from Mexico and Belize lacked chromosomes between the
sizes of 0.6 and 3.0 Mb. Strains were also examined for the
presence of the gene for an enzyme called cutinase. The
gene for cutinase was previously cloned from a strain of
C. gloeosporioides that infects papaya and the enzyme was
shown to enable the pathogen to penetrate the plant skin
or cuticle. However, DNA sequences similar to the
cultinase gene are found in only one of the Florida strains
of the citrus pathogen whereas all other strains of the citrus
pathogen contain sequences similar to the cutinase gene.
Presumably most Florida citrus pathogens do not require
cutinase in order to cause disease, perhaps due to the
limited cuticle barrier present in the flower. These
preliminary results suggest that Florida strains of the post
bloom fruit drop pathogen are likely to be quite different
genetically from type cultures and similar pathogens found
in other parts of the world. Control measures must be
fashioned to take into account this genetic variability and
the unique properties that might be expected of the Florida
strains.

Culture of Vallisneria Aquarium Plants.
Several species of the Vallisneria genus are cultured by
aquarium growers in Florida. These Vallisneria plants
constitute a large portion of the aquatic plants produced by
the growers. Competition from foreign growers during the
past few years has severely reduced profit potential for the
Florida aquarium plant growers. Foreign growers because
of their inexpensive labor, and in some cases, favorable
climates which help reduce expenses related to production
of cold sensitive plants can undercut the growers in
Florida. Plant culture techniques and methods are needed
to help Florida growers remain competitive with foreign
growers. An evaluation of a culture method that involved
placing various fertilizers as a layer under sand resulted in
production of two to three times the number of Vallisneria
plants compared to the aquarium grower's standard culture
practice of covering a layer of cow manure with sand. Use
of the fertilizer culture method by the Florida aquarium
growers may enable them to increase their production of
Vallisneria plants and help them remain competitive with
foreign growers.

Breeding Carrots for Sweetness.
In recent years a large number of new Fl hybrid carrot
varieties have been released, but most of them are superior
in yield and appearance rather than eating quality. We
have initiated a carrot breeding program that has as its top
priority the development of a carrot hybrid with sweet
flavor superior to all others. The material chosen for
parents included the open-pollinated variety 'Early Scarlet
Nantes' and a high soluble solids (high sugars) inbred
carrot line, 4367M, which has poor flavor in spite of the
high sugar content. 'Early Scarlet Nantes' is famous for its
eating quality: sweet taste (in spite of only 6-7% soluble
solids), tender texture, and good flavor. The cross 'Early
Scarlet Nantes' x 4367M was made and selection was made
for Fl roots with high soluble solids. The F2 population
from this cross was selected for root appearance, high
soluble solids, tender texture, and good flavor. We were
very surprised to obtain root selections with soluble solids
in the range of 10-11% and excellent flavor and texture.
These roots are being cross pollinated in a screen cage in
Washington state this summer. The prospects for realizing
our goals for this program are excellent. There are two
main obstacles yet to overcome. High sugar is correlated
with a tendency toward bitter or otherwise unpleasant
flavors and late flower development. We will select
strongly against both of these characteristics.

Development of New Sugarcane Cultivars.
Four new sugarcane cultivars were released following their
development through the Florida sugarcane breeding
program at Canal Point. Cultivars 'CP 82-1172', 'CP 80-
1743, 'CP 78-1628', and 'CP 81-1302' all have shown yield
potential equal to or greater than the most widely grown
cultivars. These new clones should help provide increased
genetic diversity needed to address greater disease pressure,
particularly from sugarcane rust. They all show adequate
resistance to smut, eye-spot, sugarcane mosiac virus, and
leafscald. These new clones also provide additional
choices for cultivation in more diverse environments,
although CP 82-1172 may not produce well on sandy soils.

Three New Butterhead Lettuce Cultivars for
Florida.
The lettuce breeding program at the University of Florida
began in the mid- 1970's to develop environmentally
adapted lettuce cultivars with multiple disease resistance
for production in Florida. Three butterhead lettuce
cultivars; 'Everglades', 'Florida Buttercrisp', and 'Florida
202' are in the final stages of release. All three cultivars
produce high quality heads, which are free from internal
defects such as tipbum, cracked ribs, poor color and
bitterness. The head size on all three cultivars are consid-
ered large, ranging between 13 and 16 oz. 'Florida
Buttercrisp' and 'Florida 202' are resistant and 'Everglades'
is tolerant to corky root, a bacterial root disease caused by
Rhizomonas suberifaciens. This is the most serious disease
of lettuce in Florida. All three are either resistant or
tolerant to lettuce mosaic virus, which is transmitted
through the seed. 'Everglades' is also resistant to downy
mildew and spring yellows virus. With the addition of
these three new cultivars to the two standard cultivars
presently used, a multiple cultivar use plan is being
developed. The development of this plan will help to
insure a high quality product by selecting the best adapted
cultivar for planting based on environmental and disease
conditions expected during the two month growing
period. Increased yields can also be expected over the six
month harvest period in Florida due to larger heads and
increase in the percentage of heads harvested. This could
lead to an expansion of the market share controlled by
Florida, presently at 3-4 million dollars annually.

Fertigation of Young Citrus Trees.
Over 126,000 acres of young citrus trees were planted last
year, many of which are fertigated (application of soluble


fertilizer through irrigation lines). However, no recom-
mendations exist as to optimum rates and application
frequencies in Florida. Moreover, no information concern-
ing fertigation and nutrient leaching in Florida's sandy soils
is currently available. Our results suggest that newly set
trees may be fertigated weekly, triweekly or every six
weeks without affecting tree growth provided that soil
moisture is maintained at optimum levels. Leaching of
nitrate, however, is most pronounced when infrequent,
high rates of fertilizer are applied. Growth of newly set
trees is similar whether granular or liquid fertilizer is
applied and tree response to varying fertilizer rates is also
similar to that for granular materials provided that soil
moisture is maintained at optimum levels. Application of
liquid fertilizers on a weekly or biweekly basis appears to
reduce nutrient leaching without compromising growth of
young citrus trees.

Wild, Nut-Producing, Forage Peanuts.
Two wild peanuts recently have been released by IFAS.
Major drawbacks are having to establish them vegetatively
by rhizomes and the year or so required for establishment.
Experiments have been done with nut-producing types.
One, very heavy seed-producing type, has been grown at
the AREC for more than 10 years. Last year a new effort
was begun to evaluate 11 nut-producing types. Included is
a recent Australian release that does not nodulate well and
appears very light green in color. Initial years results were
encouraging, and nuts produced were used for this years
test which includes agronomic field evaluation of single
plant plots with emphasis on quantity of seeds produced.
Also there are three field tests established in permanent
grass pastures to evaluate survival under grazing. Most of
the entries survived a low of 22 F in December, 1989, and
many had a plant diameter of more than six feet by July
1990. All germinate fast, grow rapidly, and nuts from last
season volunteered readily. Additional seeds will be
collected this year for further field testing. Commercial
harvesting and cleaning of nuts has been a constraint until
a mechanical method was developed that has been used
successfully in Australia.

Rhizosphere pH Influences Early Root
Development of Bell Peppers.
Bell peppers (Capsicum annuum L. 'Early California

pH 4.1, 5.9, or 7.3 under controlled light and temperature
conditions. Germination, emergence, shoot weight, and
root morphological characteristics were evaluated 16 days
after seeding. Taproot lengths were measured every 24 hr

from 1 to 10 days following radicle protrusion. Days from
seeding to germination radiclee protrusion) were only one
half day different among pH media treatments. Seeds in a
pH 5.9 medium emerged (fully expanded cotyledons) 1 day
earlier than seeds placed in pH 4.1 or 7.3 media. Shoot:
root ratios were not different among pH media treatments.
However, taproot growth rate from 1 to 10 days after
radicle protrusion was faster for plants grown in a pH 5.9
medium as compared with pH 4.1 or 7.3 media. Basal
and lateral root numbers averaged 1 per plant and were
minimally influenced by pH. The data suggests that acidic
or alkaline media adversely affect early shoot and taproot
development with minimal influence on days to germina-
tion or emergence, and subsequent lateral and basal root
initiation.

Stylosanthes Pasture Improvement.
Stylosanthes, a tropical legume, is widely used in the
tropics for pasture improvement. In Florida selections
have been developed which can be grown on ranches in
the southern part of the State. Two genotypes of
Stylosanthes guianensis have survived freezing temperatures
during the cold snap of December 1989. These cold-hardy
types probably could be grown further north in Florida
than most other Stylosanthes. They are early flowering
(September) and produce seed prior to the winter season in
Florida. These genotypes also have shown resistance to
anthracnose caused by Colletotrichum gloeosporioides, a
fungal disease which very severely reduces the yield of
Stylosanthes particular in the tropics. Stylosanthes is rich
in protein (20%) and is very digestible (70% in vitro
digestibility).

Improved Success in Establishing the Legume,
Aeschynomene.
Aeschynomene is the major summer legume used by
ranchers in south-central Florida. It is an annual, and once
initially seeded, it will usually regenerate from seed in
subsequent years. Ranchers can assist in this re-establish-
ment process by grazing sod close (2 to 3") in the spring,
followed by light disking. Limited rain is the major reason
for legume failure. It costs about $88/A to initially seed
and grow the crop and about $58/A to disk (regenerate)
and grow it in subsequent years. We looked at ways to
improve the chance of success so that we could make the
investment less of a gamble. Over a 5 yr period at the Ona
AREC, we studied 17 seedings of aeschynomene and
believe we can obtain 80% success if the following
conditions are met: 1) have at least 0.9" rain in the 8-d
period before seeding, and 2) soil water potential (at 3"


depth) on the day of seeding less than 150 bars tension
(-15 kPa). Soil water potential is a measure of just how
tightly the soil holds the water, and is easily measured with
an instrument called a tensiometer.

Legume Contributions to Bahiagrass Pastures.
Potential benefits of legumes in grass pastures include
improvements in performance of grazing livestock, due to
superior forage quality of pasture legumes, and addition of
nitrogen through biological nitrogen fixation. Even the
most persistent legumes often comprise only small propor-
tions of the forage available in bahiagrass pasture. It has
been more difficult to determine whether benefits were
obtained from only small proportions of legumes in
pastures (as is often the case a year or two after planting
many legumes). Management decisions such as when to
graze, how heavy to graze, and when and how much
nitrogen fertilizer to apply could be altered to optimize
benefits of sparse legume stands, if they are of benefit.
Recent research has shown growth responses by yearling
cattle when aeschynomene and phasey bean comprised as
little as 3.5% of the available forage. Cattle selectively
grazed these legumes, with diets containing much higher
proportions of legume than found in the pasture. Carpon
desmodium contributed to animal performance when
approximately 8% of the pasture forage consisted of the
legume. However, carpon desmodium was consumed in
similar proportions to those found in the pasture. Manage-
ment of legumes, comprising only small proportions of the
forage in pastures could return substantial benefits.
Management costs are not necessarily high when fencing
exists to allow controlled grazing, and may even include
the decision not to apply nitrogen fertilizer in some
situations.

Seed Priming Improves Germination and
Growth of Annuals.
Recommendations have been developed for the successful
priming of salvia, dusty miller and pansy seeds. Seed
priming consists of imbibing seeds in an osmotic solution
at a concentration that allows seeds to imbibe limited
quantities of water and go through the first steps of
germination, but does not permit radicle protrusion
through the seed coat. To successfully prime seed, the
correct priming osmoticum, amount of available water,
duration of treatment, temperature, aeration, and seed
drying and storage procedures must be determined.
Priming seeds in aerated polyethylene glycol (PEG 8000)
solutions at -0.8 to -1.0 MPa concentrations at 15 degrees









1990 Selected Research Accomplishments 17


C temperature for 7 to 10 days was found best for the
bedding plants on trial. Specific PEG 8000 concentrations
and priming durations were required for each species.
Primed seed had increased total germination, more uniform
germination, and seedlings of more uniform size. Many
bedding plant species require germination temperatures
that can not be maintained consistently in commercial
greenhouses, and frequently the species optimum tempera-
ture range is very limited. Since priming permits seed
germination above the normal temperature range for the
species, it eliminates a major problem for Florida's
producers.

Prostrate Spurge Control with Metsulfuron.
Prostrate spurge (Chamaesyce maculata) is one of the most
common summer weeds in golf courses due to its prostrate
growth habit, hard-to-kill nature with currently available
herbicides, and tendency to thrive in nematode infested
soil. Control currently involves combination ofphenoxy
and benzoic herbicides repeated every 10 to 14 days, often
resulting in undesirable bermudagrass damage. Research
was performed to investigate turf tolerance and weed
control of several recently introduced herbicides.
Metsulfuron-methyl, a substituted area, at 0.016, 0.023,
and 0.047 Ib ai per acre provide excellent (> 95%) control
without any visible damage to the Tifway bermudagrass.
Traditional treatment, 2,4-D (1.0 lb ai/A) plus dicamba
(0.5 lb ai/A), provided fair (>75%) control while
imazaquin (0.38 and 0.5 lb ai/A) provided poor (>40%)
control and also resulted in discolored turf. Metsulfuron
shows promise of excellent spurge control at ultra-low rates
without serious discoloration to bermudagrass.

Effective Growth Regulators on Cycads.
After many years of experimentation branching of cycads
was enhanced, thus forcing the plants to produce numerous
lateral shoots making their vegetative propagation possible
and permitting nurseries to grow rather than illegally
collect these ancient plants from their natural habitats, as
is currently the case. The results of this research are both
of commercial and conservation value. All cycads,
including the Florida Coontie (Zamia floridana) are
endangered and under international protection. They are,
however, much in demand by collectors and the landscape
industry. Seeds of most species are not available and their
germination is often difficult. Moreover, despite repeated
attempts by several laboratories, their tissue culture is as
yet not feasible.

Molecular Responses to Drought and Cold
Stress.
Current work is addressing the adjustment of plant
metabolism and changes in freezing tolerance during
exposure to low temperature. One of the proteins
(CAP79) synthesized at an elevated rate at 5-C with
respect to synthesis at 25~C in spinach leaf tissue has been
experimentally identified as a member of 70 kDa heat
shock gene family. This assignment is based on protein
sequence analysis of cyanogen bromide cleavage frag-
ments. Further evidence to support the assignment of
spinach CAP79 as a member of the HSP70 protein family
includes Western blot analysis using polyvalent mouse
antiserum produced with partially purified CAP79, and a
rat monoclonal (7.10) raised against the Drosophila
HSP70. Both the mouse antiserum and the rat
monoclonal antibody recognize a 79 kDa protein in
nonacclimated and cold acclimated spinach leaf tissue.
Partially purified CAP79 from cold acclimated hypocotyl
tissue crossreacts with the Drosophila monoclonal and
CAP79 antisera on one- and two-dimensional Western
blots. In hardy plant species, the other major function of
cold acclimation is the induction and maintenance of
increased freezing tolerance. To this extent, some of the
alterations in gene expression observed during cold
acclimation are considered to be decidedly linked to the
adjustments related to freezing tolerance mechanisms.
We have produced monoclonal antibodies to two other
proteins, CAPs 160 and 85. These antibodies have
allowed us to further explore the quantitative relationships
between cold acclimation, freezing tolerance and the
abundance of CAPs 160 and 85. We have measured the
response of spinach leaf and other tissues during cold
acclimation, deacclimation, and controlled desiccation
at warm temperature. These studies have shown that
nonacclimated leaf tissue contains each of these proteins,
and that they are accumulated in cold acclimated tissue
at low temperature. Preliminary experiments with
deacclimated tissue show the proteins begin to decline
upon return to warm temperature. While synthesis of
CAPs 160 and 85 is rapidly curtailed during the early
stages of deacclimation, recent Western analyses indicate
the proteins do not decline as rapidly as indicated by in
vivo labeling. With the monoclonal antibodies, we have
also been able to show that CAPs 160 and 85 are actively
accumulated in leaf tissue during desiccation. In fact, the
accumulation of these two proteins is greater during a 72
hour desiccation treatment than a seven day low tempera-
ture exposure. Turnover of drought induced CAP 160 and
85 is much slower than the accumulation, with the
turnover of these proteins being at least 96 hours. Most
exciting is that these experiments, for the first time, show a
direct molecular linkage, at the protein level, of a relation-
ship between desiccation, cold acclimation, and freezing
tolerance. Our studies of cold stress proteins indicate that
we have accidently found proteins that may play an
important role in drought tolerance responses of plants.

If this holds true, then our work may lead to information
that is extremely important in reducing crop losses to the
two most significant causes of yield reductions, drought
and low temperature.

Dry Matter Production and Perennation of
Penisetum sp. in Central Florida.
'Tifleaf II" pearl millet, a high quality, warm-season annual
forage, was compared to its perennial relative "Mott" dwarf
elephantgrass and an interspecific hybrid of pearl millet
and elephantgrass (Tift 23A N14, N23, N74) for
seasonal and total forage production, winter survival and
forage quality (protein and digestibility) under central
Florida conditions. Total forage production of the pearl
millet and the hybrid were similar in 1986 (5.5 and 6 T/A,
respectively), but the hybrid produced 15% more forage in
the late summer and fall than did the pearl millet. The
vegetatively planted dwarf elephantgrass only produced 3
T/A in 1986. Both the hybrid and the dwarf elephantgrass
survived several light freezes (min. temp. 32 deg F). Forage
production of the overwintered hybrid material and
elephantgrass were similar in 1987 (6.7 and 8 T/A,
respectively), and higher than 1987 planted, seedling
hybrid material (4 T/A). The seedling hybrid material
produced 25-30% less forage in 1987 than 1986 due to
moisture stress. In 1987 the forage quality of the
elephantgrass and the seedling hybrid material was superior
to that of the overwintered hybrid material. This was
thought to be due to higher leaf content of the
elephantgrass and seedling hybrid compared to the
overwintered hybrid.

Young Citrus Tree Fertilizer Response in
Southwest Florida.
Large areas of former pasture or range land have been
converted to citrus groves in southwest Florida. Fertilizer
rates used on the young trees have generally been higher
than the present guidelines in the literature. This study
was undertaken to evaluate current IFAS recommenda-
tions under the longer growing period of the region.
Standard water-soluble and slow-release mixed fertilizers
were applied to newly-planted 'Hamlin'/Carrizo rootstock
trees at five rates, with the lowest rate set at zero applied
fertilizer and highest at the current guideline rate for the
first year of growth. Tree growth at 1 year expressed in
terms of canopy cross-sectional area, trunk cross sectional
area, and tree height was maximum at 0.24 lbs of nitrogen
fertilizer per tree, which is slightly less than the currently-


recommended rate. Tree growth and canopy expansion
was exceptional for 1-year-old trees.

Impact of Forage Cover Crops on Tomato
Production.
The establishment of forage cover crops prior to planting
tomatoes offers many potential agricultural and ecological
benefits to the vegetable grower. Potential benefits from
using cover crops includes weed control (less herbicide),
nitrogen from mulch and roots (less fertilizer), organic
matter (OM) to enrich the soil, reduction in nematode and
insect populations, and ground cover to reduce wind
erosion (soil). Income from the sale of forages as hay or as
a seed crop may provide a secondary income to the
vegetable grower, or the forage crop could be mob grazed to
provide supplemental forage of good quality to livestock.
Efforts are in progress to determine the effect of forage
cover crops on seepage irrigated tomato production and on
emitter spacing on tomatoes grown with drip irrigation.
Soil enrichment (OM, nutrient release) from forage grasses
and legumes, nematode and insect populations.

Meristem Culture, Somatic Embryogenesis, and
Regeneration of Plantlets of Ophiopogon
japonicus.
Meristems of lily turf, 0. japonicus (Liliaceae) were grown
on a tissue culture medium without auxins or cytokinins.
Plantlets were easily regenerated from low percentages of
meristems. A large proportion of meristems developed into
plantlets or produced callus and additional plantlets if they
were transferred briefly (30 days) to medium containing a 5
uM a-napthalene acetic acid then returned to basal
medium. When calli were grown in liquid shake culture
without auxins or cytokinins, somatic embryos were
produced. Somatic embryos developed into normal
plantlets. Plantlets regenerated from somatic embryos were
freed of a potyvirus that infects most sources of lily turf.
Only 20% of plantlets regenerated from meristems were
free of the virus. Virus-free lily turf plants are now
available that grow faster and have a better appearance
than virus- infected plants. The procedures developed
appear applicable to other ornamental plants in the
Liliaceae such as Liriope and Lily.

Water Needed for Cold Protection Reduced by
Almost 60%.
Leatherleaf fern, the most valuable floricultural crop
produced in Florida, is easily cold damaged if temperatures
fall below freezing. This crop is almost exclusively pro-
tected from cold using overhead irrigation. Due to interest
in maintaining water availability and quality, research has
been conducted to reduce the amount of water necessary
to cold protect this crop. Results during a radiation freeze
with a low temperature of 23xF showed that by using a
combination of shadehouse icing ('igloo effect'),
nonporous sidewalls and frost protection sprinklers
(approximately 3 rpm) water application rates could be
reduced 60% (from the recommended 0.35"/hr rate to
0.14"/hr) without cold damage or loss of frond vase life.
During a severe advective freeze (15-20 mph winds with
low temperatures of 18xF), mature fronds were not
damaged at the reduced water application rates. However,
a majority of immature fronds were damaged as is typical
under such severe cold even using conventional applica-
tion rates. Frond color, vase life and yield were not
reduced by any treatment. These results indicate that
considerable reductions in water withdrawals for cold
protection of leatherleaf fern can be made without sacrific-
ing cold protection capabilities or crop yield and quality.

Potential of Biocides to Control Diseases and
Pests of Tomato.
Sulfhydrl proteinases have great potential as a biodegrad-
able pesticide to control bacterial and fungal diseases of
tomato. Laboratory, growth chamber, greenhouse and field
experiments have shown that papain and other sulfhydryl
proteinases are able to significantly reduce bacterial leaf
spot (caused by Xanthomonas campestris pv vesicatoria) in
tomato. when compared with copper and mancozeb
treatments, there was increased yield in biocide-treated
plots. In addition, fungi such as Fusarium and Verticillium
are effectively controlled by sulfhydryl proteinases.
Studies are currently underway to test the potential of
biocides to control nematodes and other insect pests.

Milk Production/Consumption.
Given that Florida milk production is less than milk
consumption on an annual basis, reducing the cost of the
additional milk needed is of high priority. Marketing
research has determined that the cost of obtaining addi-
tional milk supplies for Florida may be reduced by the use


of reverse osmosis, a membrane technology that removes
water from milk. The concentrated product can then be
transported from distant sources and recombined at plants
in Florida. A model of U.S. milk markets which incorpo-
rates a network flow algorithm to solve for least-cost
interregional movements of milk was developed to analyze
the reverse osmosis technology.

World Trade in Orange Juice.
A mathematical model of the world orange juice market
was completed. A stochastic simulation model which
encompassed production in Florida and Brazil, with
demand represented by the United States, Canada,
Western Europe, and Japan was developed. The model was
used to analyze the impact of reduced U.S. tariffs for frozen
concentrated orange juice, reduced duty by the European
Economic Community for imported frozen orange juice
concentrate, exchange rates, and other factors dealing with
the structure of production in Florida and Brazil.

Rural Land Values.
The annual Florida Land Value Survey involves the
estimation of the value of different types of agricultural and
rural land in the various geographic regions of the state.
For 1990, the survey revealed the agricultural land values
increased 7 to 9 percent in the Northern areas of the state
over the past year. In the South, where freeze damage was
less than in the Central areas, bearing orange groveland
increased over 12 percent and grapefruit groveland about
17 percent. The market for transition land, i.e., land
moving into nonagricultural uses, was strong in the
Northwest with increases averaging 10 percent but was
stable in other areas. Numerous concerns about the
potential effects of government regulations on land values
were reflected respondents comments.
