Abstract

Tension wood when kilndried is likely to deform hugely which is probably caused by a gelatinous layer of the gelatinous fiber To elucidate the mechanism behind the deformation of tension wood during kilndrying the strains experienced by tension wood during a hygrothermal treatment that is akin to an early stage of kilndrying were investigated Normal wood elongated along the longitudinal axis after the first treatment and leveled off with repetitive treatments During the first treatment tension wood contracted significantly along the longitudinal axis followed by small subsequent contractions which occurred during successive treatments This characteristic hygrothermal behavior of tension wood correlated with the areal ratio of the gelatinous layer One of the possible reasons why tension wood behaves differently was thought to be particular behavior of gelatinous layer This finding will contribute to the development of appropriate seasoning method for tension wood by clarifying the mechanism behind the deformation of the gelatinous layerWe are much obliged to the staffs of Northern Agriculture and Forestry Research Center in Laos Aichi Forestry Research Institute in Japan and the experimental forest of Nagoya university for their cooperation during our field work We are thankful to Dr Joseph Gril of CNRS University of Montpellier France for his valuable advice during manuscript preparation
