Abstract

The induction of the enzymes by heat shock was in the following order: cytochrome oxidase, acid phosphatase, amylase, and esterase, It indicated that different enzymes had different functions in affecting male sterility. The zymogram of seedlings differed from that of ears. It showed that the isozyme composition of the enzymes changed with plant development. When the temperature increased to 40-DEGREES-C, the bands C5 and C8 were similar to those of the maintainer line and disappeared with further increase of temperature. Those isozyme bands C5 and C8 which appeared concomittantly with male fertility may have close relation with male sterility.
