Abstract: Onion ( Allium cepa L. ) buds of cytoplasmic male-sterile( CMS) line and its maintainer line at different developmental stages were employed as experimental materials to reveal relationships between CMS and changes of endogenous hormone and prolin contents by measuring IAA, GA3 , ZR, ABA and free prolin contents. The results showed that in course of abortion, sterile buds were lower significantly in IAA, GA3 , ZR and free prolin contents, while higher in ABA contents. In anthers development stages, the difference happenned mainly in the mainpollen abortion stage( monokaryophase) . It is suggested that the contents of IAA, GA3 , ZR, ABA , and free prolinmay be related with the occurrence of male-sterile onion.

Key words: Onion, Male sterile, Endogenous hormone, Prolin
