不结球白菜雄性不育新种质不育系与保持系的生理生化分析
Physiological and biochemical analysis between a new germplasm CMS and its maintainer line of nonheading Chinese cabbage
摘要
Abstract
The leaves,buds,and flowers of the newly-bred sterile germplasm of nonheading Chinese cabbage and its maintainer line at different stages were determined in terms of soluble protein, soluble sugar, proline, O-2·, malondialdehyde and three protective enzymes: superoxide dismutase (SOD),peroxidase(POD),catalase(CAT). The results showed that the male sterile line at vegetative growth phase was near to its maintainer line in leaves' soluble protein content,but significantly lower than its maintainer line in soluble sugar and proline contents;The male sterile line at full bloom stage was higher than its maintainer line in leaves' soluble protein,soluble sugar and proline contents. The male sterile line was lower than its maintainer line in soluble protein, soluble sugar and proline contents of buds and flowers,but higher than its maintainer line in O-2·and MDA contents.关键词
