Differences in the water adsorption properties of moso bamboo (Phyllostachys pubescens) were examined by analyzing the isotherms. Hygroscopicity decreased from the bottom to the top of the culm, and this tendency was marked above about 80% relative humidity. Results of alkali extraction and the analysis of bundle sheath distribution revealed that the distribution of hygroscopic saccharides, for example, hemicelluloses and less-hygroscopic vascular bundles, affects the hygroscopicity, which varies depending on the position of the internode.
