摘　　要：在10 g/L的浓度下,乌桕不同器官粉末对生菜和小麦幼苗的生长均有较高的抑制活性,且以叶器官活性最高,果实最低。而叶在0.1～10.0 g/L的不同浓度下对夏至草、反枝苋、生菜、荠菜、小麦和黄瓜幼苗的生长具有不同程度的抑制作用,且抑制活性随浓度的增加而提高,其中以夏至草的敏感性最高,而黄瓜最低。Inhibition activety of different organs of Sapium sebiferum on seedlings growth of Lactuca sativa and Triticum aestivum is much higher at the concentration of 10 g/L,and the leaves and fruits show the highest and lowest inhibition activity respectively.Moreover,the leaves of S.sebiferum present different inhibition effects on seedling growth of Lagopsis supina,Amaranthus retroflexus,L.sativa,Capsella bursa-pastoris,T.aestivum and Cucumis sativus respectively at the concentration of 0.1~10.0 g/L,and the inhibition activety increases as the treat concentrations increase.Among all the receiver plants,L.supine seedlings present the highest sensitivity and C.sativus seedlings present the lowest sensitivity to the leaves of S.sebiferum.
