为了研究草木樨的化感作用对其他植物发芽率、生长情况的影响,试验采用草木樨植物根部、茎部及草木樨植物种子的水浸提液对稗子草的作用,来判断草木樨植物对稗子草的化感作用。结果表明:不同处理间草木樨植物的水浸提液对稗子草种子萌发和幼苗生长的化感作用具有明显的差异。草木樨根与茎的浸提液对稗子草种子发芽率有一定影响,而种子的浸提液浓度为80 mg/m L时抑制效果明显,发芽率较对照降低84.69%。综合效应指数(SE)分析可知,草木樨植物水浸提液浓度效应比较明显,即随浓度的升高化感抑制效应增强,其中根部水浸提液抑制潜力最大,根部水浸提液浓度综合效应指数由低到高分别为-0.147 3,-0.176 7,-0.464 7。
In order to study the allelopathic effect of the herbaceous plant on the germination rate and growth of other plants, the effect of plant extracts from the plant roots, stems, Allelopathy of the weeds. The results showed that there was a significant difference in the allelopathic effects of aqueous extracts from plants of different plants on the seed germination and seedling growth of. The extract of roots and stems had some effects on the seed germination rate of T. triticale. However, the seed germination rate of 80 mg / m L was significantly lower than that of the control, and the germination rate was 84.69% lower than that of the control. The results of comprehensive effect index (SE) showed that the concentration effect of plant extract was more obvious, that is, the allelopathic inhibitory effect was enhanced with the increase of concentration, of which the root inhibitory potential of water extract was the highest, the concentration of root extract The effect index from low to high were -0.147 3, -0.176 7, -0.464 7 respectively.
