Abstract

Several kinds of seeds were used as the receptor to study the allelopathy of Coreopsis lanceolata L.in different aqueous extracts.The results showed that The finally germination of Coreopsis lanceolata L.was restrained obviously,but cabbage,carrot,Hollyhock,Coreopsis lanceolata L.Influence of aqueous extracts from Coreopsis lanceolata L.on the cabbage、carrot、Coreopsis lanceolata L.germination rates was obvious,Different concentration extracts restrained the growth of cabbage and carrot in some extends,except that the 1% accelerated the growth of cabbage's seeding height.The concentration of Coreopsis lanceolata L.exhibited allelopathic promotion at low concentration and allelopathic inhibition at high concentration on the Wf of carrot,at the same of the Wf,Wt,RWC of cabbage;Wd of cabbage was restrained in extends.
