Average bloom dates for low-chill peaches of various chilling groups a
t Gainesville, Fla., depends on the amount of chilling and heat units
received. Full bloom dates for the 4 standard cultivars 'Okinawa', 'Su
nred', 'Early Amber', and 'Sunlite', (representing 150, 250, 350 and 4
50 chill units, respectively) averaged about 10 days apart over the 35
years. The order of bloom from low to high chilling groups has no rev
ersals in the last 35 years indicating the order of bloom is dependent
upon chilling requirement. However, the dates of full bloom and the d
ays separating full bloom of the standard genotype for each chill unit
group vary each year.
