| 摘 要： | 以大白菜作为受体,研究了黑松根、叶、枝条、树皮以及林下凋落物和表土浸提液对大白菜种子萌发及幼苗生长的化感作用。结果表明:各浸提液均可显著降低大白菜种子的发芽率、胚根长度及生物量,对平均发芽速率及胚轴长度则无显著影响;叶浸提液和凋落物浸提液在浓度为0.1 g/ml时可显著降低其发芽势,随浓度降低,影响则不显著,其余各浸提液则对发芽势无显著影响;在实验室条件下,叶浸提液对发芽率的影响最大,树皮浸提液对胚根生长抑制作用最强,而根浸提液在最终的生物量上抑制效果最为显著。 |

| Abstract: | The allelopathy of water extract from Pinus thunbergii root,leaf,branch,bark,litterfall and the beneath topsoil on the seed germination and seedling growth of Chinese cabbage were measured.The results indicated that all the water extracts could reduce the germination rate,radical length and biomass significantly,but had no significant effect on the average germination rate and hypocotyl length.The water extracts from leaf and litter could reduce the germination energy at the concentration of 0.1 g/ml significantly,and the inhibitions were no longer remarkable when the concentration decreased.Under laboratory conditions,the water extracts from leaf,bark and root had the most significant inhibitory effect on the germination rate,radicle length and biomass,respectively |
