摘要
以亚洲百合为供体,一串红、金鱼草、雏菊、石竹为受体,通过种子发芽试验和幼苗生长试验,初步研究了百合不同器官水浸液对几种观赏植物的化感效应。结果表明,百合鳞茎水浸液对4种观赏植物的种子发芽和幼苗的生长表现出双效性,即高浓度抑制、低浓度促进,茎叶水浸提液总体呈现出抑制作用。初步得出结论,金鱼草、一串红、石竹、雏菊4种植物的种子发芽及幼苗生长都受到百合不同部位水浸液的影响,同等情况下,茎叶水浸液的化感作用更为明显。
The paper taking Lilium Asiatic as the donor, taking Splendens, Snapdragon, Daisy, Pink as the receptor, by studying the effects of organ immersion of lily on seed germination, seedling growth and other indicators of the four receptors plant, studied on al- lelopathy effect of aqueous extraction from different organs of lily on several of ornamental plants. The results showed that water extracts of lily bulb growth of four ornamental plants seed germination and seedling showed double-effect, that was a high concentration inhibition and low concentration promoted, the aqueous extracts of stems and leaves overall showed inhibition. The preliminary conclusions are as follows： Snapdragons, Splendens, Pink, Daisy four plants seed germination and seedling growth have been affected by aqueous extraction from different parts of the lily, under the same circumstances, allelopathy leaf aqueous extracts is more obviously.
