摘　　要：以4种植物为受体,采用室内生测法研究橡胶(Hevea brasiliensis)根水浸提液对4种植物的化感作用。结果表明:橡胶根水浸提液对萝卜、白菜、绿豆和柱花草种子萌发及其幼苗生长有显著或极显著的影响,但影响各不相同;在0.05g/mL浓度浸提液处理下,4种受体植物的综合化感效应指数均为负值;化感抑制作用大小依次为萝卜>白菜>绿豆>柱花草。With 4 kinds of plants as receiver plants,indoor bioassay method was used to study the allelopathy of aqueous extracts of Hevea brasiliensis root.Hevea brasiliensis root extract had significant or remarked significant effects on seed germination and seedling growth of Raphanus sativus,Brassica rapa,Vigna radiata and Stylosanthes guianensis,but the effects were different.At the concentration of0.05 g/mL,the combined allelopathic index of the four receptor plants was negative.Integrated allelopathic effects of the average size were order to R.sativusB.rapaV.radiataS.guianensis.
