以牛膝菊为受体，研究大叶芥菜水浸提液对牛膝菊的化感作用。结果显示，浓度分别为0．25000、0．12500、0．06250、0．03125 g／mL 的大叶芥菜水浸提液对牛膝菊种子的萌发抑制效应以0．25000 g／mL 最高，平均抑制率为56．03％；低浓度（0．03125 g／mL）处理对牛膝菊种子萌发基本上没有抑制作用。此外研究发现，大叶芥菜水浸提液对牛膝菊胚根、胚芽的萌发和鲜质量积累都有明显的抑制作用，对鲜质量平均抑制率分别为75．75％、35．82％、17．48％、18．81％；对牛膝菊种子萌发、胚根、胚芽、鲜质量的化感综合效应分别为60．36％、30．45％、14．23％、16．50％。结果表明，大叶芥菜对牛膝菊有很强的化感潜力，能为牛膝菊的绿色防控提供理论依据。

Galinsoga parviflora Cav.was used as a receptor to evaluate the allelopathic effects of water extracts of Brassica juncea var.foliosa L.H.Bailey.Of the concentrations tested (31.2,62.5,125 and 250 mg/mL),the highest one, 250 mg/mL was the most inhibitory (56%) of G.parviflora seed germination whereas the lowest concentration (31.2 mg/mL)did not affect germination.The water extracts of B.juncea var.foliosa inhibited growth of radicle and seedling,the inhibition rates were 76%,36%,17%,19%,respectively;the overall allelopathic effect on the seed germi-nation,growth of radicle and seedling,and fresh weight of G.parviflora were 60%,30%,14%,16%,respectively.In conclusion,B.juncea var.foliosa has strong allelopathic effects on G.parviflora,a property that can serve as the basis for the green control of this weed.
