| 摘 要： | 用枯落物浸提液生物鉴定的方法，研究马尾松林下常见草本、灌木种对其幼苗生理活性的化感作用。结果表明：两供体对受体光合色素含量和质膜相对透性的影响，总体表现为促进作用；对受体光合速率和蒸腾速率的影响，基本表现为抑制效应。对氮吸收的影响草本表现出微弱的抑制效应，灌木表现出高促低抑的作用规律；对磷吸收的影响两供体表现出相反的作用趋势，而对受体钾元素的吸收，两者均表现出一定的促进效应。

| Abstract: | The allelopathy effects of the common herbs and shrubs （ donor plants） under forest on the physiological activities of Pinus massoniana seedlings （receptor plants） were studied by means of biological identification of the litter extract solution. The results showed that chlorophyll content and cell membrane permeability of the receptor plant were generally increased with different treatments of the two donor plants, but the photosynthetic rate and transpiration rate of the receptor plants were basically reduced with the same treatments. The nitrogen absorption of P. massoniana seedlings was slightly inhibited by herbaceous plants＇ solution and by lower concentration of shrub plants＇ solution, while it was promoted by high concentration of shrub plants＇ solution. And the allelopathy effect of the donor plants on phosphorus absorption of the P. massoniana seedlings was in the opposite trend. Both the donor plants solutions had promotion effect on potassium absorption of P. massoniana seedlings. |
