| Abstract:
Bloom and maturity dates of 17 peach cultivars were recorded during four different seasons. The elapsed time between these two dates, the accumulated head units for this period over 10°C, Linsser's constant and the correlation between early growing season temperature and elapsed period between bloom and maturity were worked out. It was found that the number of days required to mature peach cultivars during different years was very close to their mean, indicating that a tentative date of picking can be predicted if the date of full bloom is recorded. The Linsser's ratio was found to be within a close range for different seasonal temperatures and the elapsed period between bloom and maturity for certain cultivars, suggesting that warm weather following bloom shortened this period and vice versa in such cultivars. | |
