Don). The fast-grown trees have shorter tracheids. In the load-deflection type having the large plastic region, tracheid length is shorter and fibrils lie more flatly and bending modulus of elasticity is lower on the same specific gravity as in other two load-deflection types. The trees in this type, therefore, seem to be more juvenile. Moreover, much proportion of the trees in this type belongs to the fast-grown group. Then, by all meams, the precise information of wood quality is necessary for the utilization of fast-grown cultivars.
