英文摘要Laboratory bioassays were conducted to investigate the allelopathic effects of seed aqueous extracts of four wetland species (Sagittaria trifolia, S. lancifolia, Polygonum hydropiper and Monochoria korsakowii) on seed germination and seedling growth of one crop species (Brassica rapa spp. pekinensis) and two wild wetland species (Oryza rufipogon and M. korsakowii). All cover seed extracts resulted in a significant initial delay in germination of B. rapa spp. pekinensis and O. rufipogon. But, four days after first germination, only the inhibition with 3.75% extract was significant on B. rapa spp. pekinensis; and seven days after first germination, 1.25%, 2.50% and 3.75% extracts had statistically similar accumulative germination with the control on O. rufipogon. Among the extracts, only S. trifolia extracts performed a significant promotion of M. korsakowii germination. Both inhibitory and stimulatory responses of root and shoot growth were observed. Root growth of B. rapa spp. pekinensis and shoot growth of M. korsakowii were significantly inhibited by 3.75% extracts of all cover species, while root growth of O. rufipogon. was significantly promoted by all cover seed extracts. The results suggest that the seed-to-seed allelopathic effect may have significant implications on the organization of plant communities.
