| 摘 要： | 为探讨水稻穗部内源激素含量随穗分化进程的变化动态及其与穗部性状的关系,本研究以2个直立穗型粳稻品种为试材,分析了正常生长及在不同发育时期喷施赤霉素(GA3)时,幼穗内源生长素(IAA)、玉米素核苷(ZR)、脱落酸(ABA)与赤霉素含量的变化动态及其与穗部性状的关系.结果表明:随穗分化进程,穗部GA3含量呈现先降后增的"...

| Abstract: | In order to explore the dynamic change of endogenous hormones in developing panicle and its relationship with the characteristics of panicle two erect panicle japonica rice varieties were selected and the dynamic changes of IAA(Indoleacetic acid),ZR(Zeatin nucleo-tide),ABA(Abscisic acid) and GA3 levels in young panicle were analyzed under both normal and exogenous GA3-treated conditions.The results are as follows: during young panicle differentiation,endogenous GA3 content presented a reverse-L type i.e.,th... |
