Description
We estimated the role of mycorrhizal fungi quantitatively in a Japanese red pine (Pinus densiflora) forest. We directly estimated several parameters to calculate the amount of carbon consumed by mycorrhizal fungi, such as the biomass of fungi in ectomycorrhizal fine roots and fine root biomass, and drew other parameters from the literature. Our study site, a Japanese red pine forest, was characterized by a very small ectomycorrhizal fine root biomass (only 91.0gm-2) and small fungal content in ectomycorrhizal fine roots (2.2%) compared with the literature data. The ectomycorrhizal fine root biomass has a greater influence than the fungal content of ectomycorrhizal fine roots on the difference in fungal biomass in ectomycorrhizal fine roots among forests. The total biomass of ectomycorrhizal fungi in ectomycorrhizal fine roots and in soil was estimated to be only 10.0gm-2. However, the total amount of carbon consumed by the production-death decomposition cycle of ectomycorrhizal fungi was estimated to be 117.0g C m-2 year-1, which corresponds to about 24% of carbon release from soil as soil respiration. Our estimation reconfirmed the importance of ectomycorrhizal fungi in forest carbon cycling. The carbon consumed by ectomycorrhizal fungi is not negligible, even in a stand having a very small biomass of ectomycorrhizal fungi.
