Succession of ectomycorrhizal communities and mycorrhizal functioning for regeneration of pine seedlings in coastal pine forests.

日本沿海松林一直遭受松材枯萎病的侵袭，其防灾功能和景观功能可能都在下降。为了利用共生真菌的生物资源种植松苗，使沿海森林得以延续和维持，本项目采用形态学和遗传学的方法对林内的外生菌根群落进行了研究。外生菌根真菌的物种多样性低于内陆森林生态系统。不完全真菌中，在所有研究点松树的外生菌根中以新球菌（cenococum geophilum）为主。这些结果表明，外生菌根真菌群落比内陆森林简单。

Japanese coastal pine forests have been suffering from pine wilt disease, and thus both disaster preventional and scenery functions might be declining. For the continuity and maintenance of coastal forests by way of pine seedling planting with bio-resources of symbiotic fungi, the project was carried out ectomycorrhizal community in the forests with morphological and genetic methods. Species diversity of ectomycorrhizal fungi was less than that from inland forest ecosystems. Imperfect fungi, Cenococcum geophilum was dominated as ectomycorrhizal roots of pine trees in all of study sites. These result indicated that ectomycorrhizal fungal community is simpler than inland forests.
