Abstract: The male sterile plants were significan tly higher than male fertile plants during rosette and anthesis in recessive genic male sterile AB line in Chinese cabbage (Brassica campestris L．ssp． chinensis Makino)． Cyanide-ilsistant respiratory rate of buds in male fertile plants were significantly higher than that in male sterile plants．Buds of male sterile plants had deficient IAA an d surplus ZT．The bands of peroxidase isozyme of middle and big buds in male fertile plants were moil obvious than in male fertile plants．There were two tapes of cytochrome oxidase isozyme of little and mi ddle buds and moil obvious in male fertile plants．There were two specific tapes in soluble protein electrophoilsis in male fertile plan ts，and one in male sterile plants．

Key words: Chinese cabbage, Male sterility, Cyanide-resistant respiration, Hormones, Isozymes, Protein SDS-PAGE electrophoilsis
