Abstract:

In the experiment , Allelopathy of Medicago sativa on Dactylis glomerata L was studied through stem leaf water extract in seedling stage. It turned out that allelopathy of Medicago sativa on Dactylis glomerata L was evident. Eurek and Baralfa obviously inhibited germination and seeding growth ,but promoted leaf dry weight. Sanditi and Sadie was not significant on seeding length of Dactylis glomerata L.,but it can inhibited seeding length.Moreover, The results also show that the allelopathic inhibition rate increased with intense concentration of the water extracts.
