Abstract: Taking leaf allelochemical of Jatropha curcas Linn.as donor,Ageratina adenophora(Sprengel)as receptor,the effects of the aqueous leaf extract,the aqueous leaf volatile substance solution and decomposed leaf liquids of Jatropha curcas on biological activity of Eupatorium adenophorum were studied by using pot experiment.The results showed that the content of malondialdehyde(MDA),and soluble protein,activities of superoxide dismutase(SOD)and peroxidase(POD)were changed differently with allelopathic effects of Jatropha curcas.Under different concentrations,the contents of MDA and soluble protein,the activities of POD and SOD increased in the early phase,decreased in the late phase.The order of allelopathic effects fromJ.curcas was decomposed leaf liquids>the aqueous leaf extract>the aqueous leaf volatile substance solution.Those results suggested that J.curcas allelopathy could use for E.adenophorumcontrol.
