摘　　要：运用CH2Cl2提取水培35d鹰咀豆的根系分泌物,并通过气相色谱和质谱联用技术(GC MS)进行分离鉴定,对典型分泌物苯甲醛的生物学效应通过发芽试验进行了测试。结果表明,鹰咀豆的根分泌物主要包括有机酸、酚、烃类、酯、酮类、醇、酰胺、苯、醛和噻唑等;苯甲醛是一种他感作用强于自毒作用的化感物质,对2种幼苗组成的复合系统的负效应小于对单作系统的负效应。Root exudation of Cicer arietinum seedling was extracted and identified by gas chromatography-mass spectrometry (GC-MS) by CH_2Cl_2,35days after hydro-culturing, and the biological effect of the typical exudation benzaldhyde was tested by the way of germination experiments in this study. It indicated that the component of the exudation mainly include organic acid, phenol, hydrocarbon, grease, ketone, mellow, amide, benzene, aldehyde and thiazole et al. Typical exudation benzaldhyde was a kind of allelochemical showed stronger allelopathic effect on other crops than on Cicer arietinum itself, and the negative effect of benzaldhyde on multiple systems composed by two kinds of seedlings was weaker than on mono system.
