The biomass of above- and under-ground parts were studied in stands of bamboo grass, Sasa kurilensis and Sasa senanensis, with different stand heights to compare their plastic variation of mass allocation between organs depending on the culm height. The mean stand heights were 59-261 cm in S. kurilensis plots, and 30-107 cm in S. senanensis plots. Mean stand height reduced distinctly toward the upper part of hillside. The stand height of bamboo grass might be affected by stress such as high wind or thin snow. The above-ground biomass decreased, and culms, branches and leaves became smaller where mean culm height was limited. Whereas culm density, branching pattern, mean life span of culm and the number of leaves per centiare did not change as much in both species. S. senanensis showed small changes in the C/F ratio and T/R ratio with culm height, and its mass allocation between organs was rather stable irrespective of culm height. S. kurilensis showed obvious changes in organ allocation with a reduction of culm height. In S. kurilensis, the mass of culm and branch decreased significantly and rhizome mass increased relatively in under-ground parts because the culm base mass had reduced with decreased culm height
