%X By means of bioassay in laboratory and field,this paper studied the allelopathy of 18 kinds of plants in Gansu Province on the seedlings of wheat,cucumber and radish.The results showed that the aqueous extract of the stems and leaves of Artemisia annua,Solanum nigrum and Datura stramonium had the strongest allelopathy on test receptor plants,and their synthetic inhibitory effect (SE) was 47.66%,32.89% and 26.63%,respectively.The SE of Xanthium sibiricum,Portulaca oleraca,Cephalanoplos segetum,and Chenopodium album was 21.71%,20.93%,20.83% and 20.2%,respectively,while Vicia amoena (SE 3.5%),Setaria viridis (SE 2.2%),and Cymamchum chinense (SE 1.97%) had a weaker allelopathy.Chenopodium ambrosioides (SE -1.03%),Polygonum caespitosum (SE -1.63%) and Avena fatua (SE 5.33%) had no evident allelopathy,but Artemisia annua affected the seedling height and fresh weight of radish,cucumber,wheat and maize,with the SE being 54.07%,38.46%,33.35% and 20.88%,respectively.Artemisia annua had a 44.70% of SE on wheat growth,and thus,had a certain value to develop and use.
