    History and Accomplishments of the U.S. Horticultural Research Laboratory
    By Doris Stanley
    June 21,1997

    First established in 1892 at Eustis, Fla., the U.S. Horticultural Research Laboratory was originally created to study citrus blight and improve citrus varieties. Severe freezes in 1894-95 prompted scientists to add research on cold hardiness. The lab was relocated to Orlando in 1931.


    The lab now has about 80 employees, including 20 senior scientists, at the main site on Camden Road and three other locations—the 500-acre A.H. Whitmore Foundation farm near Leesburg and laboratories at Plymouth and Fort Pierce.


    In addition to researching all aspects of citrus growth, survival and production, researchers develop methods to control pests, diseases and postharvest problems of other subtropical fruit, vegetables and horticultural crops.


    Major milestones for the U.S. Horticultural Research Laboratory:


    1930 - Released the Orlando tangelo to Florida nurseries. Growers currently harvest tangelos valued at more than $10 million from more than a million Orlando trees.


    1945 - Established fresh fruit maturity standards for marketing oranges and, in 1953, for grapefruit.


    1972 - Introduced a family of microhymenoptera parasites to control scale insects and, in 1979, helped Florida state scientists (who had originally used a chemical control) identify a different family of the parasites that control citrus blackfly. Because of this work, neither scale nor blackfly is considered a threat to Florida citrus.


    1973 - Designed the fiberboard box now used for exporting all citrus fruit.


    1974 - Released Swingle citrumelo citrus rootstock to nurseries. Determined its resistance to citrus nematodes in 1981 and its tolerance to citrus blight in 1988. Swingle now makes up 51 percent of Florida's nursery stock.


    1979 - Helped the citrus industry design semirigid insulation wrap that protects young citrus trees from freezing. This wrap is now used extensively by citrus growers.


    1982 - Developed cold treatment for grapefruit that allowed export to Japan and other quarantine countries and states. In the same year, developed heat treatments to disinfest citrus nursery trees of nematodes and for specific nematode problems in 1985.


    1989 - After 26 years of breeding, introduced Ambersweet, the first cold-hardy orange. Growers have already planted about 5 million Ambersweet trees.


    1990 - Found three nematode species that biologically control citrus root weevil. Growers throughout Florida are now using the nematodes, which are being produced commercially.


    1990- Developed a test to rapidly diagnose citrus blight, a disease that kills about half a million citrus trees annually.


    1992 - Patented a practical, reliable test to differentiate strains of citrus tristeza, a virus that can kill trees.


    1993 - Successfully inserted a green fluorescent protein gene from a jellyfish into citrus plant cells, the first time this type of signal gene has been transferred into plant cells. This research should speed up the process of identifying genes responsible for traits such as improved fruit quality and resistance to disease, pests and environmental stresses like cold, drought and salinity.


    1994 - Found 20 different forms of plant defensive proteins—chitinases and chitosanases—in oranges and grapefruit. These compounds could help protect trees and fruit from pathogens, insects and harmful nematodes.


    1995 - Discovered that gibberellic acid helps maintain high levels of chitinase in grapefruit long after levels usually diminish, thereby extending the self-protection period. Also purified from grapefruit peel a protein inhibitor, polygalacturonase (PGIP), that is associated with fungal resistance. This could help protect grapefruit from fungal attack.


    1996 - Found that major commercial varieties of blueberries produced in the Southeastern United States tolerate low-dose irradiation without affecting quality. For blueberries, this is the only known feasible alternative to methyl bromide, the currently used fumigant that will be banned in 2001.


    1996 - Discovered that translucent polyethylene mulch films keep purple nutsedge from emerging, growing and reproducing in Florida's vegetable fields. Few chemicals other than methyl bromide, which is slated to be banned in 2001, are available to control nutsedge. Nutsedge is one of the 10 most troublesome weeds that plague Florida vegetable crops.
