Brassidium hybrid orchid leaves were sent to the University of Florida Plant Disease Clinic in the summer of 2002. Symptoms on leaves were a spreading, cottony, white mass of mycelium with necrotic centers 3 to 5 × 5 to 9 mm. Approximately 1% of leaves submitted were affected. Sclerotium rolfsii Sacc. was isolated from the affected leaves using acid potato dextrose agar (APDA) (1). Two plastic boxes were lined with wet paper towels and 6 uninoculated leaves were placed in each. Three leaves in each box were treated as controls and received 3 mm2 of APDA, while the other three leaves in each box received 3 mm2 of S. rolfsii culture on APDA. All leaves were misted with water and enclosed to maintain humidity. Twenty-four hours later, infection was visible on two treated leaves. Within 72 h, significant infection was visible on three of the six inoculated leaves. All control leaves remained uninfected. S. rolfsii was consistently reisolated from the inoculated leaves, fulfilling Koch's postulates. Over the past 12 months, S. rolfsii has been detected in 30% of commercial orchid nurseries as well as homeowner orchid collections in Miami-Dade County, Florida. No resistance to this disease in orchids has been reported. To our knowledge, this is the first report of S. rolfsii on this orchid hybrid. Reference: (1) J. Tuite.

During the past 10 years, the Florida strawberry growers, through the Florida Strawberry Growers Association, have made a serious commitment to fund university research on strawberries. They have purchased equipment and donated monies for facilities at Dover. They have also helped support a new faculty position in breeding and genetics. During this same period, the University of Florida has made an equally strong commitment to support strawberry research and extension. These commitments are beginning to pay significant dividends for industry and the University. Cultural and pest management information has been generated that is saving the industy money, and the breeding program is developing new cultivars that will keep the industry competitive in the marketplace. The University has benefitted through the acquisition of new facilities, equipment, and faculty and graduate student support.

Red LaSoda is the red-skinned fresh-market potato standard for Florida. It was observed in 1949 as a deep red mutant of LaSoda in the Louisiana potato breeding program. It has been in trials over many seasons and at many locations in Florida including university and grower sites. Production and quality results provided in this 4-page fact sheet are summarized from the red-skinned fresh-market trials conducted by the University of Florida over the past 14 seasons. Written by Lincoln Zotarelli, Doug Gergela, Chad M. Hutchinson, David Dinkins, and Edsel Redden, and published by the UF Department of Horticultural Sciences, August 2013. http://edis.ifas.ufl.edu/hs323

Good Agreement

Over the past two decades, selections that produce crisp-textured blueberries have been noted by breeders. Research was conducted to determine how these selections differ from standard cultivars. Four blueberry clones with crisp texture were compared, using firmness, with 94 advanced selections from the University of Florida blueberry breeding program. The clones, tested for berry firmness with an Instron machine, produced a normal distribution. The crisp clones were at the high end of the distribution, but were not qualitatively different from other firm-fruited selections. Firmness was tested during final stages of berry development to determine if crisp clones softened more slowly than standard cultivars. In both 2003 and 2004, firmness decreased greatly from the white to pink stages of development, with slower loss of firmness thereafter. Crisp and commercial clones were similar in the timing of firmness loss. Berries from six crisp clones and four firm commercial cultivars were subjected to shear cell tests to see if the two groups could be distinguished. Shear cell tests from early and late harvests in the same year showed good agreement. Three of the four crisp clones were much higher in shear force than the other clones tested. A consumer sensory panel was conducted to determine if the average person could distinguish between the berries of crisp and standard cultivars. Ninety-five subjects were given two samples each of crisp and non-crisp blueberries, and asked to designate the one sample they thought the most crisp. Seventy-five subjects chose one of the two crisp clones and 20 chose one of the standard clones. This research indicates that crisp texture in blueberry exists and is recognizable and repeatable, but is difficult to objectively define.

Plant Sap

Seventy-five percent (75%) of U.S. produced winter snap beans are grown on limestone soils in southern Dade County, Florida Since this crop requires 60-70 days from planting to harvest, growers need information to make changes in fertilizer practices on an almost instantaneous basis. As part of a study to calibrate soil tests with yield responses to different levels of applied fertilizers, plant sap quick tests are being calibrated with laboratory analyses of whole leaf samples. Beans were grown at two locations -- in a grower's field and at the University of Florida Tropical Research & Education Center (TREC). Samples were taken simultaneously for both plant sap quick tests using petioles and for whole leaf tissue analyses. Results and how these have been extended to local growers will be presented.

Low Dispersion

During the past several years, a systematic search for novae in the Magellanic Clouds has been carried out at Cerro Tololo Inter-American Observatory. The Curtis Schmidt telescope, on loan to CTIO from the University of Michigan is used to obtain plates every two weeks during the observing season. An objective prism is used on the telescope. This provides additional low-dispersion spectroscopic information when a nova is discovered. The plates cover an area of 5°x5°. One plate is sufficient to cover the Small Magellanic Cloud and four are taken of the Large Magellanic Cloud with an overlap so that the central bar is included on each plate. The methods used in the search have been described by Graham and Araya (1971). In the CTIO survey, 8 novae have been discovered in the Large Cloud but none in the Small Cloud. The survey was not carried out in 1974 or 1976. During 1974, one nova was discovered in the Small Cloud by MacConnell and Sanduleak (1974).

Support Facility

The University of Iowa Central Electron Microscopy Research Facility(CEMRF) was established in 1981 to support all faculty, staff and students needing this technology. Initially the CEMRF was operated with one TEM, one SEM, three staff members and supported about 30 projects a year. During the past twelve years, the facility has replaced all instrumentation pre-dating 1981, and now includes 2 TEM's, 2 SEM's, 2 EDS systems, cryo-transfer specimen holders for both TEM and SEM, 2 parafin microtomes, 4 ultamicrotomes including cryoultramicrotomy, a Laser Scanning Confocal microscope, a research grade light microscope, an Ion Mill, film and print processing equipment, a rapid cryo-freezer, freeze substitution apparatus, a freeze-fracture/etching system, vacuum evaporators, sputter coaters, a plasma asher, and is currently evaluating scanning probe microscopes for acquisition. The facility presently consists of 10 staff members and supports over 150 projects annually from 44 departments in 5 Colleges and 10 industrial laboratories. One of the unique strengths of the CEMRF is that both Biomedical and Physical scientists use the facility.

The University of Florida / IFAS South Florida Beef Forage Program (SFBFP) is composed of county Extension faculty and state specialists.  The members, in conjunction with the UF/IFAS Program Evaluation and Organizational Development unit, created a survey in 1982, which is used to evaluate ranch management practices.  The survey is updated and distributed every 5 years to ranchers in 14 South Florida counties: Charlotte, Collier, DeSoto, Glades, Hardee, Hendry, Highlands, Hillsborough, Lee, Manatee, Martin, Okeechobee, Polk, and Sarasota.  The responses are anonymous.
