摘要
研究表明,转基因抗虫棉及其受体整个生育期内功能叶片MDA、脯氨酸、叶绿素和内源激素ABA含量变化趋势较一致,因年际间气候环境的影响而有所波动。双价基因抗虫棉内源激素IAA含量苗期低,中后期功能叶含量增高。SOD酶活性表现为苗期较低,而随生育进程均在8月8～9日出现峰值而后下降。
In insectresistant transgenic cotton varieties (G. hirsutum L.)harbouring doublegene(Bt+CpTI) and their receptor varieties, the trends MDA, proline, chlorophyll and endogenous ABA contents in the main functional leaves in the whole growth period are similar, and there is still fluctuations among years because of the climate conditions. The content of endogenous IAA is low in seedling period and increases in latter periods. The activity of SOD is consistent among years, lower in seedling period, up to the high peak on 8th and 9th August, and descending afterwards.
