Impact of invasion of pine wood nematode on the growth of dominant shrub Pleioblastus amarus in Pinus massoniana communities

摘要: When pine trees are invaded by wilt diseases, the severely infected will die and fall down, or they be removed when found to damaged disease. It gives rise invasion of other species in these empty niches originally occupied trees, i.e., competing surrounding understory shrubs invade during following years. As a result, spatial distribution pattern main tree forest change, niche variety population occur. In end, direction succession restoration ecosystem affected. our study, Pinus massoniana with dominant shrub, Pleioblastus amarus, was wood nematode clear cut. Selecting this community as research object, we studied effect on growth P. forest. Our results show that, after attacked were removed, amarus shrubs, which benefited its climax. Growth at climax stage greater compared unhealthy control group.
