Abstract: The dynamic changes of the indole acetic acid (IAA),gibberellin (GA3),zeatin (ZT) and abscisic acid (ABA) contents in flower buds of tobacco cytoplasmic male sterility (CMS) and homolog maintainer lines were determined by high_performance liquid chromatogram.The results showed that from small bud y middle bud y big bud,the content of IAA and ZT incMS buds were higher than in maintainer line buds.While the content of GA3 and ABA incMS buds were lower than in maintainer line buds.It was suggested that the changes of endogenous hormone contents were closely related with the occurrence of cytoplasmic male sterility.

Key words: Tobacco, Cytoplasmic male sterility, Development of flower bud, Endogenous hormone
