摘要
银杏雌花芽形态分化前的５月初，ＺＴ（玉米素）、ＡＢＡ（脱落酸）处于高峰，ｉＰＡｓ（异戊烯腺嘌呤类）的高峰晚２０ｄ出现；６月份，随着形态分化开始，ＺＴ、ｉＰＡｓ和ＡＢＡ的含量下降并维持低水平；１１月开始落叶时ＡＢＡ含量迅速上升。ＩＡＡ（吲哚乙酸）在５月中旬出现峰值，进入６月形态分化开始后则在略低水平上波动，９月底开始缓慢下降。
The variation in contents of ZT,iPAs,IAA,and ABA during the differentiation of female flower bud of Ginkgo were measured with ELISA.Results showed that the contents of ZT,iPAs,and ABA had a crest value before the differentiation of female flower bud,and it was low in June.The contents of IAA had several crest value during the differentiation of female flower bud.
