Abstract: Changes of contents of IAA,ABA,GA3and ZR in anther at different development stage in Cytoplasmic Male Sterility (CMS)line and its maintainer of Chinese cabbage were investigated by ELISA (enzyme-linked immunosorbent assay).It is observed that changes of contents of IAA,ABA,GA3and ZR in anther of CytoplamicMale Sterility line were different to its maintainer.At the third stage (the length of flora bud was 2.0-3.0 mm),the contents of IAA,GA3and ZR incMS and the value of ZR/ABA were remarkably lower than its maintainer.However,the contents of ABA incMS were significantly higher than its maintainer.The microspores have just started to be sterile at this stage.It is concluded that the deficiency of IAA,GA3and ZR and over product of ABA and breaking of hormonal equilibrium induced male sterility in Chinese cabbage.
