| Abstract: | In order to reveal the allelopathy of Flaveria bidentis grown in Hengshui Lake on Brassica napus and Lactuca sativa,it was studied that allelopathic effects of aqueous extracts from root and stem+leaf crumbs of F.bidentis on the seed germination and seedling growth of B.napus and L.sativa.The study indicated that the aqueous extracts of F.bidentis had significantly depressed seed germination and germination speed index of L.sativa,but did not affect that of B.napus.The aqueous extracts of F.bidentis also si... |
