摘要(Abstract)：

以9a生红灯甜樱桃(Prunus avium L.)为试材,对其果实不同发育时期果肉及种子中内源激素含量的变化动态进行了测定分析,结果表明,甜樱桃果肉及种子中内源激素含量与其果实的生长发育有密切关系。果实发育第Ⅰ速长期(盛花后5～15d),果肉中生长促进型激素(ZRS、IAA和GAS)含量均较高,进入硬核期(盛花后15～25d)均呈下降趋势,其中IAA和GAS均降到最低值,随果实的第Ⅱ次速长果肉中ZRS、IAA和GAS含量均迅速增加且分别出现最大值;与之相反,种子中ZRS、IAA和GAS含量在第Ⅰ、Ⅱ速长期较低,在硬核期含量最高,这与甜樱桃果实及种子的生长规律相吻合。果肉中ABA含量分别在盛花后5、15和35d出现高峰,与甜樱桃的落果(花)时期基本一致。
