摘要:
以三叶草(Oxalis corymbosa DC)为供体植物，以其根、茎和叶的水提液为化感物质，以三叶鬼针草(Bidens pilosa L.)种子为受体，采用培养皿滤纸法进行化感试验，测定了三叶草的根、茎和叶的水提液对三叶鬼针草的幼苗根长、苗高和鲜重的化感作用。结果表明：三叶草不同部位的水提液对三叶鬼针草种子的萌发及其幼苗生长有明显的化感作用，且不同浓度（0.05、0.10、0.20 g/mL）水提液对三叶鬼针草的影响存在差异，浓度为0.20 g/mL时抑制作用最强。
Abstract:
Taking Oxalis corymbosa DC as the donor plant,its root,stem and leaf water extract as allelochemicals,Bidens pilosa L.seed as the receptor,using the petri dishes with filter paper method to test allelopathy,the impact of the root,stem and leaf of Oxalis corymbosa DC water extraction liquid on root length,shoot height,fresh weight of Bidens pilosa L.seedling were determined.The results showed that the different parts and different concentrations water extraction of Oxalis corymbosa DC had obvious allelopathy on Bidens pilosa L.seed germination and seedling growth,and the effect of different concentrations（0.05,0.10,0.20 g/mL）on Bidens pilosa L.had differences,and when the concentration was 0.20 g/mL,the inhibition was the strongest.
