| 摘 要： | 通过对4个烟草雄性不育系及其保持系不同大小花蕾的SOD、POD和CAT活性的测定,研究烟草雄性不育性与花蕾中SOD、POD和CAT活性的关系。结果表明:4个不育系的小、中、大花蕾SOD活性都比其相应的保持系更高;除MS云烟85的小花蕾POD活性低于其保持系外,各不育系不同大小花蕾的POD活性都比其相应的保持系高;4个不育系的小、中、大花蕾的CAT活性都不同程度地低于其保持系。

| Abstract: | Activities of superoxide dismutase(SOD),peroxidase(POD),and catalase(CAT) in different size flower buds were detected with 4 tobacco cytoplasmic male sterile(CMS) and their homolog maintainer lines.Results showed that activities of SOD in small,medium and large flower buds of 4 CMS lines were higher than those in their corresponding maintainer lines.Activities of POD in all CMS lines' flower buds were higher than those in maintainer lines except the small buds of MS Yunyan 85.Activities of CAT in different ... |
