Abstract:

Rhododendron  is one of traditional flowers in China, and it has excellent ornamental and application values. Survival of rhododendron under severe natural environment is intimately related with ericoid mycorrhiza.  To carry out studies on ericoid mycorrhiza is not only of important value for rhododendron garden application, but also of great significance for species diversity conservation. This paper expounds the biodiversity of ericoid mycorrhizal fungi and its function in rhododendrons growth and development. This study will surely lay a solid foundation for further utilization and mechanism exploitation of ericoid mycorrhizal fungi.

Key words: ericoid mycorrhiza, biodiversity; , heavy metal tolerance; , mechanism of action
