| 摘 要： | 通过分光光度法，对油菜细胞质雄性不育系09A和保持系09B不同发育时期花蕾中POD、CAT、SOD、APX的活性和MDA、游离Pro含量进行了测定，并讨论分析了与雄性不育之间的关系。结果表明：不育系09A不同发育阶段花蕾中CAT、SOD、APX三种酶活性均低于09B；POD活性在不育系花蕾发育早期低于09B，但随着花蕾的发育，09B的POD活性逐渐下降，而09A的POD活性则逐渐升高；不育系09A的MDA含量在整个花蕾发育过程中均高于09B，而Pro含量则低于09B。

| Abstract: | The enzyme activities of the rapeseed cytoplasmic male sterile lines of 09A and fertile lines of 09B,including peroxidase(POD),catalase(CAT),superoxide dismutase(SOD) and ascorbic acid peroxidase(APX) of different development stages of bud,were assayed by using spectrophotometry,the relationship between four kinds of protective enzyme activity and cytoplasmic infertility were investigated in this paper.At the same time,the content of malondialdehyde(MDA) and free proline were also assayed by spectrophotomet... |
