摘　　要：以10个东北大面积推广的大豆品种(北豆18、绥农10、丰豆3、黑农28、东豆339、中黄13、合丰55、垦鉴豆35、黑农44和垦丰16)为材料,采用盆栽试验探索大豆在不同生育时期(V1、V3、V5、R2和R4)的根际土、根、茎和叶的甲醇提取液对瓜列当种子萌发的刺激效果。结果表明:不同大豆品种的甲醇提取液对瓜列当的诱导效果存在显著差异;中黄13的根际土对瓜列当的刺激作用显著高于其它品种;大豆V3和V5期的植株提取液对瓜列当的诱导作用最强;大豆的根、茎和叶对瓜列当的诱导效果为根>茎>叶。在瓜列当危害区,大豆可以作为瓜列当的"诱捕"作物。Methanolic extracts of rhizosphere soils and plant tissues（roots,stems and leaves）from ten soybean varieties（Beidou 18,Suinong 10,Fengdou 3,Heinong 28,Dongdou 339,Zhonghuang 13,Hefeng 55,Kenjiandou 35,Heinong 44 and Kenfeng 16）were collected to research their allelopathic potential on stimulating O.aegyptiaca seeds germination at different growth stages（V1,V3,V5,R2 and R4）under pot experimental condition.The results displayed that there was a significant difference among soybean varieties on inducing O.aegyptiaca seeds germination.Rhizosphere soils of Zhonghuang 13 induced significantly higher germination rates of O.aegyptiaca than the other varieties.The soybean samples collected at V3 and V5 induced higher germination than the other stages.Seeds germination rates induced by methanolic extracts of roots were higher than that of stems and leaves.In conclusion,soybean could be used as a trap crop for O.aegyptiaca in the infected field.
