玉米C型胞质雄性不育与可溶性糖、可溶性蛋白、游离脯氨酸含量的关系
Relationship between contents of soluble sugar,soluble protein and free proline and C-cytoplasmic male sterility in maize
摘要
Abstract
In order to make further study on the biochemical mechanism of C-cytoplasmic male sterility of maize,C478,478 and H01,the cytoplasmic male sterility line and its maintainer and restorer line of maize were used as the raw material to comparatively analyze the contents of soluble sugar,soluble protein and free proline in their tassel florets.The results showed that soluble sugar content in the male sterility line was significantly higher than its maintainer and restorer in every stages except the elongation of leaves.The soluble protein contents had little difference among three lines. Free proline content in the male sterility line was significantly higher than its maintainer and restorer line in every stage except the tasseling of leaves. As the tassel developed,soluble sugar in the maintainer line was significantly higher than the male sterility line in stage Ⅱand stage Ⅲ.Soluble protein content in the male strerility line was lower than that of its maintainer and restorer line in every stage of florets development,and the difference was obvious in stage Ⅱand stage Ⅲ. Free proline content in the male sterility line was significantly lower than that of its maintainer and restorer line in every stage of florets development.关键词
