休息完成的日期很少用于确定落叶果树的冷冻单位和生长度小时要求。一个统计过程已被开发，允许这些常数被确定从温度数据和盛开的日期。开花日期计算模型使用的统计推导出的常数比较有利的观察日期的盛开。
Dates of rest completion are rarely available for determining the chill unit and growing degree hour requirements of deciduous fruit trees. A statistical process has been developed which permits these constants to be determined from temperature data and dates of full bloom. Bloom dates calculated from the model using the statistically derived constants compare favorably with observed dates of full bloom.
