摘　　要：为研究不同生长时期东北红豆杉(Taxus cuspidata Sieb.et Zucc.)针叶内防御蛋白的变化,分别对5、7、9月份的东北红豆杉雌、雄株针叶内防御蛋白PPO、PAL、POD、CAT、TI和CI活性进行了分析。结果表明:不同生长时期东北红豆杉防御蛋白的活性差异显著(P<0.05),除POD活性在9月份达到最高值外,PPO、PAL、CAT、TI和CI的活性均在7月份达到最高值;不同生长时期雌、雄株防御蛋白活性的变化趋势基本一致。We measured the activities of PPO, PAL, POD, CAT, TI and CI in the leaves of female and male Taxus cuspidate Sieb. et Zucc. in May, July and September to investigate the seasonal variations of defense protein activities in leaves. The activities of defense proteins were all significantly different among the different months （P〈0.05）. The activities of PPO, PAL, CAT, TI and CI all peaked in July, and the activity of POD peaked in September. The female and male tree leaves were in the same trend.
