| Outline of Final Research Achievements |
We investigated whether or not ectomycorrhizal fungal infection resources with broadleaf tree species (Fagaceae, Betulaceae) exist in arbuscular mycorrhizal cypress artificial forest. In the boundary area between the cypress plantation and secondary forests, ectomycorrhizal communities were similar to broadleaf tree side observed up to 5 m on cypress side, which is thought to be the effect of extraradical mycelium. Soil propagule bank communities were detected in samples up to 10 m from the boundary, but both infection resources are considered to be difficult ectomycorrhizal formation such as places far from the boundary.
Planted broad-leaved saplings which had no mycorrhizal formation were small in growth, and almost seedlings have died, that indicates whether or not ectomycorrhizal formation is important affects the growth and survival. Also, it was suggested that the colonization of ectomycorrhizal fungi may influence the diversity of the rhizosphere bacterial community.
