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.
