The purpose of this report is to clear the wood qualities of Sugi (Cryptomeria japonica) and Hinoki (Chamaecyparis obtusa) of underplanting trees in two-storied forest compared with single-storied forest.When underplanting trees are grown up under suitable light conditions, no difference in length of tarcheids and rings from the pith of boundary of juvenile wood region between the underplanting and single-storied trees is recognized. Boundary of juvenile wood, whereas, for underplanting trees grown under poor light condition was larger than that of sutable light condition.The specific gravity of underplanting Sugi trees slightly higher than that of the single-storied ones. The same tendency is recognized in underplanting Hinoki trees under poor light condition.There is, however, no distinct difference between underplanting Hinoki trees under suitable light condition and single-storied ones.There is no significant difference in compressive strength for both species between underplanting and single-storied trees.

本研究旨在明确二层林和单层林下栽树的材性。在适宜的光照条件下，两层林下栽树与单层林相比，在幼龄林区果肉长度和年轮长度上无明显差异。幼林边界，而弱光条件下栽植的树大于适光条件下的树，杉木林的比重略高于单层树。在弱光照条件下栽植Hinoki树也有相同的趋势，但在适宜光照条件下栽植Hinoki树与单层栽植Hinoki树没有显著差异，两种树种的抗压强度在栽植后与单层树木之间也没有显著差异。
