Abstract

The merchantable ratio for bamboo, Phyllostachys bambusoides Sieb. et Zucc, was calculated with the data from 200 felled culms collected at Mt. Toshima, in the eastern part of Kumamoto City, by assuming the merchantable diameter being 4-7 cm. Because of the difference in culm form, the merchantable ratio for P. bambusoides was higher than that for Phyllostachys pubescens Mazel ex Houz. The combination of the determined ratio and the one-way volume table constructed in a previous study enabled us to develop a one-way merchantable volume table for P. bambusoides. The volume table allowed to estimating the merchantable apparent culm volume, and will be effective when conducting the effective utilization of bamboo resources.
