摘要:

The effect of the temperature on floral induction and development in white sapote cv. 'Florida' was investigated under field, glasshouse and growth chamber conditions to identify the effective temperature for floral induction in order to grow the crop in the warm region of Okinawa. Floral induction was observed at a mean temperature below 20 deg C. Under 30-15, 30-20 and 30-25 deg C day-night temperature regimes, however, the trees did not produce panicles within 85 days of treatment indicating that the day temperature of 30 deg C might have inhibited floral induction. The emergence of panicles was obvious within 19, 23 and 30 days under the day night temperature conditions of 25-10, 20-10 and 15-10 deg C, respectively. Also, the cumulative temperatures, assuming 5 deg C as a base temperature, were 199, 198 and 197 degree-days, respectively. Moreover, it is likely that floral differentiation occurred within a short period of time under inductive conditions which usually prevailed from November to December, depending on the years in Okinawa.
