Outline Activities
Research

1. Relationship of Wood Anatomical Features to Permeability and Fxation of Preservatives.
Impregnation and Fixation of preservatives are closely related to wood anatomical features. In this study, flow paths using CLSM and micro-distribution of preservatives using SEM-EDXA are visuallized and relationship among permeability, fixation and wood anatomy are studied.

2. Black heartwood formation of Cryptomeria japonica.
Variation of heartwood color in Cryptomeria japonica is large and black color restricts use of heartwood for decorative purposes. Because of high geen moisture content, drying and transport costs are high. In this study, distribution of potassium that related to blakening in heartwood is clarified and mechanism of black heartwood formation is studied.

3. Evaluation of Wood Quality and Cultivation of Fast Growing Trees for Sustainable Wood Utilization"
Cultivation of fast growing trees with high ability of carbon stock and evaluation of wood quality is important for creation of sustainable resources. We are studying about Melia azedarach. Variation of wood properties is clarified and possibilities of use and tree breeding for wood quaility are studied.

4. Shrinkage and Anisotropy of Tracheid Cells with Desorption using CLSM or LV-SEM.
As for checking during drying, visualization of shrinkage of wood cells with time is important for high quality dried wood. In this study, 4-dimensional changes of wood cell with desorption are visualized and shrinkage and anisotropy are studied.

5. Formation and Properties of Root Wood.
Cambial activity of root, root wood formation and propterties are unknown. In this study, seasonal change of root cambium, elongation from fusiform initial to wood fiber and microfibril angle are studied in relation to cambial age and environmental factor.
