Abstract:
By indoor bioassaying distilled water,the water extract of root,stem and leaf(0.01,0.05,0.10 g/mL) were applied to testing their effect on seed germination and seedling growth,The germination rate,germination index,root length,seedling height,and other indicators of allelopathic effect index were figured out and measured.In order to study the water extracts of Andrographis paniculata(Burm.F.)Nees on seed germination and seedling growth.The results showed that,various concentrations of Andrographis paniculata(Burm.F.)Nees stem and leaf aqueous extracts significantly inhibited the germination rate,root length and shoot growth of Andrographis paniculata(Burm.F.)Nees seed germination,all of them had reached a significant level;with the concentration of the water extracts of Andrographis paniculata(Burm.F.)Nees stem leaves increasing,its germination rate,root and stem elongation of Andrographis paniculata(Burm.F.)Nees seed inhibition would enhance.Andrographis paniculata(Burm.F.)Nees root aqueous extract various concentrations inhibited the growth of Andrographis paniculata(Burm.F.)Nees seed germination rate and root,and this inhibition effect increase with the concentration increasing,but they promoted the growth of stem.Andrographis paniculata(Burm.F.)Nees vegetative had the effect of allelopathic autotoxicity.
