Biochemical Characteristics of the Anthers and Leaves of Cytoplasmic Male Sterility Line and Its Maintainer in Cabbage

The contents of anther hormones,free amino acids and chlorophyll in CMS158,a cytoplasmic male sterility line,and its maintainer,were comparatively examined.It was shown that the KT and IAA content in the anthers of the male sterility line were significantly lower than those in the anthers of the maintainer and there existed no obvious difference between the GA contents in the anthers of the male sterility line and its maintainer.The content of free amino acids in the anthers of the male sterility line was extremely higher than that in the anther of the maintainer,the contents of proline and cystine contents in the anthers of the male sterility line were extremely lower than those in the anthers of the maintainer,there was no significant differences between the lysine contents of the male sterility line and its maintainer;threonine were not detected in the male sterility line and its maintainer and the contents of the other amino acids were higher in the male sterility line than in the maintainer;the highest serine content appeared in the anthers of the male sterility line and the highest proline appeared in the anthers of the maintainer and the aspartic acid and proline contents in the anthers of the male sterility line and its maintainer.The anthers of the male sterility line did not significantly differed from those of the maintainer in chlorophyll content.
