| 摘 要： | 不同抗枯萎类型棉花品种（系），在病害胁迫时，叶片组分内ＳＯＤ、ＰＯＤ活性呈明显规律性变化。研究结果表明，抗病品种ＳＯＤ和ＰＯＤ活性弱，可溶性蛋白质含量高；不抗病的品种则表现趋势相反，膜脂过氧化水平、ＳＯＤ和ＰＯＤ活性都较高，可溶性蛋白质含量较低，差异达极显著水平。同时发现ＳＯＤ和ＰＯＤ活性与田间发病指数呈明显的正相关。

| Abstract: | Various Fusarium wilt tolerant cotton cultivars,changes of enzyme activities inblades were studied under disease infection. The disease-resistant cultivars displayed weakSOD and POD activities and high soluble protein content,but the susceptable cultivars were onthe contrary. Within one cultivar, the membrane lipid peroxidation and enzyme activities of in-fected plants were significantly higher than that of non-infected plants,and the soluble pro-tein of infected plants was significantly lower than that of non-infected plants. In addition,SOD and POD activity was found to positively correlated with the field disease index. |
