Study on mutual allelopathy between invasive plant Galinsoga parviflora and Trifolium repen
Year: 2015
Type: article
Abstract: By using seed germination method in culture dish,different concentrations(0.625,1.250,2.500,5.000,10.000 g/L)of water extracts form the upper part of Trifolium repen and Galinsoga parviflora were prepared,the mutual allelopathy between T.repen and G.parviflora was studied,to determine whether T.repen could replace G.parviflora in the similarity habitat,and to provide scientific basis for the biological control of G.parviflora and the development of new weed killer.The results showed that,water extracts of G.parviflora had certain inhibitory effect on seed germination,radicle length,ratio of root and stem of T.repen,with the increase of concentration,these traits decreased gradually.The extracts of T.repen exhibited inhibitory effect on seed germination,radicle length,ratio of root and stem of G.parviflora at 10.000 g/L,and had apromotion effect at low concentrations.Within the limits of concentration in the test,the comprehensive effect of G.Parviflora on T.repen was less than 0,it exhibited inhibitory effect,and the extracts of G.parviflora had the greatest inhibitory effect at 10.000 g/L.While T.repen exhibited inhibitory effect,and the comprehensive effect of T.repen on G.parviflora was less than 0 at 10.000 g/L;T.repen had apromotion effect on G.parviflora at other concentrations.The conclusion suggested that T.repen to replace G.parviflora under the same habitat should be careful.
