杜鹃花类菌根研究进展

Research advances on ericoid mycorrhiza.

杜鹃花类菌根是指杜鹃花科几个属植物上形成的一种特殊类型的菌根共生体,它可以帮助植物缓解环境的胁迫,使其在逆境下生存。为了发掘和利用菌根的潜能,满足生态建设和园艺生产的需要,杜鹃花类菌根的研究在国外受到广泛关注。该文从菌根的解剖结构、菌根真菌的物种多样性、菌根效应等方面对杜鹃花类菌根的研究现状进行了综述,并探讨了该研究存在的问题和发展前景。

Most members of family Ericaceae have a distinctive form of the symbiosis referred to as ericoid mycorrhiza,which appear to be able to alleviate certain environmental stresses and so facilitate the establishment and survival of Ericaceae.In order to understand and utilize the mycorrhizal potentials,and satisfy the requirement of ecological construction and horticulture production,ericoid mycorrhiza has attracted abroad attention in overseas.This paper summarizes the research advances on the structure of Ericaceous root,the diversity of ericoid mycorrhizal fungi and the effects of inoculation on host plants.The insufficiency and prospect of the mycorrhizal research are also discussed.
