内容記述（抄録等）
The production structure of 6 plots of MAATE selection forest was investigated from 1967 to 1969.
1. Dry weight of stem, of branch and of foliage has a correlation to its trunk size given by D^2H.
2. Dry weight of growing stock, of branch and of foliage per ha varied 66.3-154.5, 12.5-27.8, 11.8-24.9 ton respectively.
3. Ratio between the weight of foliage(ton) and stem volume increment(m^3) in each plot ranged from 0.52-1.15, and same ratio of felled trees for mensuration in each plot decreased from 0.86-1.05 to 0.52-0.89 as the upper storied crown to the under stroried one.
