Research Abstract	We studied the ability of ectomycorrhizal fungi to absorb cesium (Cs) for clarifying the effects of mycorrhizal fungi on absorption of Cs into trees. Nutrition of Cs by ectomycorrhizal fungi was different depending on the strain used and type of N source in the culture medium. Rock weathering ability, which is related with the release of Cs from clay mineral, is also variable in the strains used.
