The purpose of this study was to investigate variabilities in green moisture content, specific gravity and shrinkage in the stems of a Larch(Larix leptolepis) to provide fundamental information for technical processes. There were significant differences in green moisture contents, specific gravity and shrinkage between heratwood and sapwood. The green moisture content was correlated negatively with the height in the sapwood. On the other hands, in the heratwood, there was a positive correlation between moisture content and the height. There were no significant differences in specific gravity between south-bound and north-bound directions in both heartwood and sapwood. There were no significant differences in specific gravity due to the height in sapwood, but significant differences were foundin heartwood. There were no significant differences in shrinkage between south-bound and north-bound directions, and due to the height in most of heartwood and sapwood. However, shrinkage in north-bound direction was higher than that of in the south-bound direction in some sapwoods.
