| Abstract: | The allelopathic influence of water extraction of invasive plant Erigeron canadensis L.was investigated.The water extraction was applied to Oryza sativa L.and Brassica campestris L.to test the number of the germinated seedings and the length of the root of the receptors.The results showed that the invasive plant.Canadensis L.inhibit the receptor's seedlings germination and length of root,and delayed the germinations. |
