Research Abstract

The microcracks occurring during drying of wood were visualized in situ under confocal laser scanning microscopy (CLSM). Precise control of relative humidity and temperature in a specialized environment chamber made it possible to acquire sequential images of the woods of Cryptomeria japonica, Acacia hybrid (A.mangium×A.auriculiformis) and Melia azedarach during drying from the green condition. Our technique made it possible to discuss the relationship between moisture content and microcrack formation during drying and clarified relationship of wood structures to microcrack characteristics. We found the CLSM technique to be an effective method for visualizing microcrack propagation with time.
