Abstract:: Taking annual Tagetes patula L. as test material，the effect of Tagetes patula L.aqueous extract solution on seed germination of perennial ryegrass was studied，in order to understand the allelopathy of Tagetes patula L. on seed gemination of perennial ryegrass.The results showed that the aqueous extract solution from different parts of Tagetes patula L.all had obvious allelopathy on seed germination of ryegrass.The aqueous extract solution from root and stem of Tagetes patula L.under a concentration of 25% obvious accelerated the seed germination of ryegrass.The effect was better for aqueous extract solution of root than that of stem.However，the aqueous extract solutions under other treatments all inhibited the seed germination，with the order being flower>stem>leaf>root.These results preliminarily confirmed that Tagetes patula L.exists potentiality of allelopathy.
