This study was conducted to evaluate the performance of Sugi lamina impregnated with low-molecular weight phenolic (LMWP) resin using the full cell process followed by curing at high temperature. In this study, penetration of LMWP resin into finger-jointed lamina was examined. Physical and mechanical properties, such as surface hardness, dimensional(More)
The mechanism of differentiation of tracheid (earlywood or latewood) should be elucidated to improve the wood properties of sugi trees (Cryptomeria japonica). Water deficit affects tracheid differentiation in conifers. However, the signals, which transmit the information of water contents in the soil to the differentiating tracheid, remain unknown.

In this study, we examined past growth traits of hinoki (Chamaecyparis obtusa) trees by stem analysis, as well as growth traits in the years when the rings at breast height were formed. We tried to clarify the effects of growth traits in the ring-formed years on the wood properties of the rings from juvenile to mature wood. Height to diameter ratio (H/D)(More)
