摘　　要：运用组织培养技术,将三叶青的组培苗和驯化苗分别用于检测三叶青营养器官叶、茎和块根水提液的化感自毒作用。实验结果表明:三叶青各营养器官水提液均对受体植株的株高、根长和株鲜重产生不同程度的抑制作用。该抑制作用随水提液的浓度增加而增强且具有器官差异性。这些结果提示:三叶青存在化感自毒作用。The tissue culture plants and acclimation plants were applied separately on the test for allelopathic autotoxicity of Tetrastigma hemsleyanum Diels et Gilg＇s extracts from leafs, stems and roots by tissue culture technology. The results showed： all extracts separately down-regulated the value of height, length of root and weight of whole plant; moreover, the inhibition was dose-dependent in different organ. These preliminary data indicated that allelopathic autotoxicity exists in Tetrastigma hemsleyanum Diels et Gilg.
