华南地区严重危害入侵植物薇甘菊和五爪金龙入侵机制研究

Invasion Mechanisms of the Exotic and Noxious Invasive Plants Mikania Micrantha and Ipomoea Cairica in South China

薇甘菊(Mikania micrantha H.B.K.)和五爪金龙(Ipomoea cairica(L.)Sweet)是近年来在华南地区造成严重入侵危害的2种恶性杂草.该文综述了它们与入侵性相关的生理生态特征以及化感作用.同时,根据2种植物在入侵机理方面的研究现状,分析和展望了后续研究中值得关注的研究方向.

Many areas in South China nowadays are seriously suffering from invasion by the alien invasive plant Mi- kania micrantha H. B. K. and lpornoea cairica （L.） Sweet. In this article, the research progresses on the invasion mechanisms of these two noxious species, including their invasive ecological and physiological characteristics, and allelopathic effects are illustrated. Based on the current research status on the invasion mechanisms of these two in- vasive species, further research fields that need focus are also analyzed.
