Abstract:
The allelopathy of two kinds of  Chromolaena odorata blade aqueous extracts on seeds germination of Festuca rubra,Medicago sativa,Lolium perenne and Brassica oleracea were investigated by means of petri dishes and filter papers.One of those two kinds  Chromolaena odorata comes from original country (Mexico) and the other comes from invaded area (Sipsongpanna).The results showed that the allelopathy of blade aqueous extracts were different among those tested plants,with Medicago sativa being the most effected,Festuca rubra being more effected than Lolium perenne and Brassica oleracea being the least effected.It also showed that the concentrations of aqueous extracts were proportional to the strength of allelopathy.By comparing the allelopathy of original with invasion,it found that there was no significant difference between those two kinds Chromolaena odorata,which indicated that the allelopathy wouldn’t play an important role in fragrant eupatorium herb’s invasion.
