摘要
科学判断种子适宜收获时间对于优质种质资源的保存、利用与开发以及提高种子品质与产量等农业生产实际问题均具有重要意义。本文综述了几种可以科学判断种子最佳收获时间的方法:根据种子形态变化(颜色、粒重)及成熟状态(生育期、种子成熟后损失情况如落料与裂荚等)、根据种子内部生理指标变化(含水量、浸出液电导率、发芽指标、内含物以及抗逆性)以及一些其它指标(积温与综合判断指标);并进行了研究展望,提出了今后此类研究的方向及应该注意的问题。
Judgment of seed optimum harvest time has important significance to high quality germplasm resource conservation, utilization and development. This study presented several methods that can judge the optimum seed harvest time according to the seed morphological changes （seed color and weight） and mature state （growth period and loss situation after seed maturation such as seed shedding and shatter- ing）, physiological changes within the seeds （water content, electric conductivity, germination index, inclusion and stress resistance） and some other index （growing degree days and synthetic judgment index）. Further studies in this fields and issues that might be occurred are also addressed in the paper.
