摘　　要：该试验研究了艳光、大久保和仓方3个桃品种分别在-10℃、0℃、10℃和20℃条件下贮藏时,随着贮藏时间的延长对其花粉生活力的影响。结果表明:不同温度下贮藏的花粉生活力随着贮藏时间的延长均呈下降的趋势,0℃贮藏下的花粉生活力下降最为缓慢,20℃贮藏条件下花粉生活力下降最为迅速。刚开始贮藏时不同品种之间的花粉生活力也存在明显的差异,艳光的花粉生活力最强,为89.2%;仓方的花粉生活力最低,仅为78.6%。并且不同品种花粉的耐贮性也不相同,大久保花粉的耐贮藏性最好,艳光和仓方花粉的耐贮性相差不大。In this experiment, pollen viability of ＇Yanguang＇, ＇Dajiubao＇, and ＇Cangfang＇peach varieties storing at -10℃, 0℃, 10℃and 20℃ for different time was determined. Results indicated that the stored pollen viability decreased with the time of storing, and it decreased the slowest at 0℃ and the fastest at 20℃. The pollen viability was different among varieties at the beginning of storage, ＇Yanguang＇was the most of 89.2%, while ＇Cangfang＇ the least of 78.6%. The storability of pollen of different varieties was different, ＇ Dajiubao＇was the best, ＇ Yanguang＇ and＇ C angfang＇ was the same.
