CELERY BOLTING TRIAL/

J. M. White and E. A. Wolf of f


Nine lines or cultivars of celery were evaluated for bolting (premature
development of the seed stalk) in the Lake Jem area. Seeds were planted in
bed in the area and plants transplanted on February 5, 1980. There were more
hours of cold weather during the seedbed growing period than normal and
freezes occurred February 26 and 27. The cold weather was such that this test
for bolting would be a good test. Bolting results as determined by counting
four replications of 25 plants each are presented in Table 1. Counts were
made 79 days after transplanting when the field was ready for harvest.

In another bolting and yield trial, three lines and one cultivar were
evaluated. This test was conducted in the Oviedo area. Seeds of the 3 lines
were grown on ground beds in the Oviedo area and transplanted on February 15,
1980. Florida 2-14 plants were grown in the Belle Glade area. The harvest
results of April 30, 1980, (85 days after transplanting) are in Tables 2-4.
Florida 2-14, the check used in this test,was observed to be a slightly shorted
plant, but the length of the longest outer petiole to the first node (Table 2)
was longer, but not significantly, than the 3 lines tested. Florida 2-14 did
not produce as many large (size 1 1/2 or greater) plants as the 3 lines;
therefore, Florida 2-14 did not have as high a total weight as the 3 lines
(Table 2).
