摘要: 用入侵杂草一年蓬(Erigeron annuus)地上部分的水浸提液对几种经济作物种子进行萌发培养实验,分别测定种子的最终萌发率、根长以及苗高来研究一年蓬是否存在他感作用。结果表明:(1)一年蓬的化感作用是存在的;(2)一年蓬水浸提液在高浓度下对作物种子萌发、根长和苗高均有明显的抑制作用,而在低浓度下则对长梗白菜、番茄的苗高具有促进生长的作用。

Abstract: The extract from the organs above ground of Annual Fleabane(Erigeron annuus) was used to treat the seeds of some crop seeds, we determined the seeds germination, the length of root and seeding height of four crops.The results were as follows:(1) the allelopathic effects of Annual Fleabane does exist.(2) Higher concentration of the water extract of Annual Fleabane could restrain the seed germination and infancy developing, while lower concentration of the water extract could accelerate developing seed of Brassica chinensis var.communis and Lycoperiscum esculetum.

Key words: invasive plant, annual fleabane(Erigeron annuus), allelopathy, seeds germination
