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.
