以离体油菜子叶为材料,研究了营养胁迫诱导的子叶衰老过程中吲哚乙酸氧化酶(iaa氧化酶)和细胞分裂素氧化酶活性的变化。
the activity of iaa oxidase and cytokinin oxidase was significantly higher in cms anther, but the activity of tryptophan synthetase was lower than in fertile anther.
iaa氧化酶和细胞分裂素氧化酶活性表现为不育系高于其相应的可育系,色氨酸合成酶则是不育系低于其可育系。
changes of the activity of iaa oxidase, tryptophan synthetase and cytokinin oxidase in sterile anther, leaf and ovule were similar to those of phytohormones.
棉花细胞质雄性不育花药、叶片和胚珠中,iaa氧化酶、色氨酸合成酶和细胞分裂素氧化酶活性的变化与内源激素含量的变化基本一致。
