| 摘 要： | 比较和研究了我国新疆棉区及黄河长江流域棉区98个不同棉花品种和品系的抗早衰特性及早衰发生的动态消长规律。结果发现，不同棉花品种抗早衰特性存在着明显的差异，抗早衰、中抗早衰、感早衰、极感早衰品种分别占所试品种3.06%、18.37%、60.20%和18.37%。该结果大致反映了目前我国各棉区大多主栽品种抗早衰遗传基础差。早衰发生的动态消长规律研究结果显示棉花早衰具有普发、暴发和不可逆的特点。基于早衰对我国目前棉花生产危害状况，就有关防治策略和措施进行了探讨。

| Abstract: | The characteristics of anti-premature aging and dynamic development process of the premature aging for 98 different cotton varieties planted in Yellow River,Yangtze River and in Xinjiang cotton region were studi-ed.The results showed that the characteristics of different cotton varieties were significantly different in resistance to premature aging.The varieties resistant,moderately resistant,or sensitive,or extremely sensitive to premature aging accounted for 3.06%,18.37%,60.20% and 18.37% of the tested va... |
