| 摘 要： | 研究了商陆、落葵、毛叶子花和配伍植物(板蓝根等20种植物混合)的水提取液对感染TMV烟叶中自由基含量和TMV增殖的影响,并探讨了其防治TMV的效果。结果表明,不论在接种TMV毒液之前施用,还是接毒后施用上述植物提取液都能使O2·-和.OH含量降低,且对TMV增殖有较好的抑制作用,其中配伍植物提取液对TMV的防治效果优于单一植物提取液,并且预防效果大于治疗效果。

| Abstract: | The inhibitory effects of plant extracts on free radicals and multiplication of TMV were studied.The results showed that the single plant extracts and mixture extracts of many plants had strong inhibitory effects on free radicals and multiplication of TMV either before or afterinoculation by TMV.The mixture extract had better effects than any single extract in controlling TMV.The defending effect was greater than curing effect. |
