| 摘 要： | 对杉木自毒作用研究表明，杉木纯林中的土壤、枯落叶、半分解枯落叶和杉木鲜叶、枝条、树皮、树根的水浸液及其添加乙烯吡咯啉酮ｋ３０（ＰＶＰ） 的溶液对杉木种子、空心菜种子和萝卜种子的萌发均有影响．所有水浸液均表现出高浓度下抑制种子萌发，随着浓度降低，抑制作用减弱、消失，甚至转变为促进作用的规律；其中根和鲜叶水浸液抑制作用最强，但水浸液添加ＰＶＰ 后抑制作用明显减弱，且在低浓度时表现出促进作用．

| Abstract: | Studies on the autointoxication of Chinese fir show that the aqueous extracts of surface soil, leaf litter, half decaying leaf litter, fresh leaf, branch, bark and root in pure Chinese fir plantation and their polyvinyl pyrrolidone k30 (PVP) solutions affected the seed germination of Chinese fir, Raphanus sativous and water convolvulus. At high concentration of aqueous extracts, seed germination was significantly inhibited, while with decreasing concentration, the inhibitory effects got weaker, disappeared and even turned into stimulating effects. The aqueous extracts added PVP significantly weakened the inhibitory effect, and exhibited enhancement effect at low concentration. |
