studied with Dr.
Marcela holds a

influence of nucleotides and their possible
role as flavor enhancers in citrus juice.
Citrus Canker Update
CREC employees are reminded that there
are state regulations on citrus canker
decontamination and disinfection of
personnel, clothing, equipment and vehicles
when working with citrus, or entering a grove
or greenhouse with citrus. There are also
restrictions on the movement of plants and
fruit off-Center. Speak with your supervisor
if you have questions on the use and type
of decontamination chemicals; there is an
approved chemical list for personnel/
clothing, and another approved chemical list
for equipment/vehicles. Website links are
Statewide, there is concern that the
summer's hurricanes have helped spread the
disease. In October, one of the state's largest
citrus canker outbreaks was found in
commerical trees in Charlotte County. In
recent weeks, 21 infected residential trees
infected were found in Port St. Lucie, located
in Florida's largest citrus producing county.
In December, there was an infected
residential tree in Palm Beach county

Since the canker outbreak in 1995, the
state has destroyed more than 2.4 million
trees in commercial groves and 650,000 trees
in residential areas.

Tables, blues This year's holiday festivities at CREC featured a Table Decorating Contest. Creativity and color dominated the
competition. Winners, who were selected by a vote of CREC personnel at the Centerwide meeting on Dec. 17, were treated to lunch. "Best
Holiday Theme" winners were Jill Dunlop and Rhonda Schumann for their grand fruit centerpiece pictured below (handmade with real fruit
dipped in sugar). In a close contest, Dennis, Monica and son Andrew Lewandowski were awarded "Most Original" for their hurricane-
ravaged gingerbread village with blue "tarp-covered" roofs and a devastated citrus grove (made of greenery and Trix cereal). Second place
went to Gretchen Baut and George Brinkley (Photolab) with a table centerpiece of snowmen, made out of oranges, gazing at a Christmas tree.
All of the tables, featured here, were beautiful and creative. Thanks to all of participated, and to Gretchen Baut, Jill McDonald and Alta
Church for coordinating the contest! Photos by Gretchen Baut and Monica Lewandowski.

Happy Holidays -
A record 250 people attended the CREC
holiday party on December 17 at BHG.
The Administrative Infrastructure and
friends, a small army of people, prepared
and hosted the holiday events, including
the end-of-year Centerwide meeting. In
addition, CRE s grove, packinghouse
and facilities crews harvested, washed
bagged and delivered citrus fruit for
CREC, and fresh citrus was delivered to
the UF campus in Gainesville. Shelby
Graham headed up a hard-working food
committee, and Troy Gainey solicited
funds and donations from faculty to
supplement the budget. Thank you to
all who donated extra money towards
the party, it was appreciated by all!
