THE PERFORMANCE OF ASSORTED FLOWERING ANNUALS
AT THE GULF COAST RESEARCH AND EDUCATION CENTER:
SPRING 1984

T. K. Howe and W. E. Waters


The usefulness of observing new cultivar releases under central Florida
conditions has been recognized by IFAS in the establishment of a variety
evaluation program at the Gulf Coast Research and Education Center in
Bradenton. Since the inception of the program, particular annual floral
crops have been selected for intensive study in consecutive trials such
that the fall and spring seasons could be compared. Marigold and zinnia
were evaluated in 1982, impatiens in 1983, and petunia in 1984.

However, it became apparent that observational trials would be appropriate
to observe numerous species in single, unreplicated plots. This was not
to replace the formal, replicated trials on single crop species but rather
to allow the program to keep abreast of the many new releases seed companies
make every year.

In the spring of 1984 the first observational trial of flowering annuals
was conducted and ninety cultivars from 21 genera were examined in single
plots as bedding plants. Seed was sown in vermiculite and germinated
under environmental conditions as required for each species. Seedlings
were transplanted to ToddS planter flats (1 x 1" cells, model 150) filled
with a peat:vermiculite medium (1:1) amended with superphosphate, micro-
nutrients and dolomite. The plants were fertilized with 20-20-20 (rates
and times varied) and were transplanted into field beds when large enough
to handle easily. The plants were set into unfumigated, raised,; plastic
mulched, 30"-wide beds in which Osmocote 18-6-12 was incorporated across
the top of the bed at the rate of 1740 lb/A (9.6 lb/100 ft of bed). Plants
were placed on 12 inch centers in three rows across the beds with 8 plants
per plot. Irrigation water was supplied by seepage from lateral ditches
spaced every 7 beds. The trial was conducted in full sun. Botrytis was a
problem after April 24th, and several fungicide sprays were applied.

Data was taken on the number of days to flowering from transplant date,
flower size and color, plant dimensions and miscellaneous observations. A
final subjective rating was given to each plot at the end of the season
when plants were generally past their prime to identify cultivars which
had good performance in hot, rainy weather. Observational results are
presented in the following Table.

Director, respectively.
