The differences among four Sasa communities were investigated on both above ground biomass and nutrient concentrations. The largest diameter and height of culms were observed in Sasa kurilensis communities. The amount of leaves increased with the increase of culm biomass, with the maximum of 500-600 g/m^2 in all Sasa communities of open plots. Among open plots, the amount of above ground biomass was closely related to the number of culms in each species, and these relations showed segregation among the species. In under canopy plots, both the amount of above ground biomass and the number of culms were controlled by the shading due to overstory. There were three different tendencies on the seasonal change of the nutrient concentrations. The nutrient concentrations in culms and leaves increased with leaf-layer ascending. Among four species, nutrient concentrations of culms in Sasa Veitchii and S. senanensis, and of leaves in S. kurilensis and Sasamorpha borealis were higher than in other two species in both open plots and under canopy plots.
