Outline of Final Research Achievements

Aboveground net primary production of Cryptomeria japonica and Chamaecyparis obtusa plantations were estimated by measuring the biomass, growth and litterfall in the Kyushu Island. Effects of environmental conditions, plantation age, cultivar and forestry operations on the production were investigated. The relationship among above mentioned variables were also analysed. The aboveground net primary production of 140-year-old C. japonica plantation was comparable to that of an adjacent secondary forest, though the production was affected by previous thinning. A strong thinning affected the production of C. japonica plantation, though there was no difference in the production between medium and light thinning. There were more than 30% differences in tree height and growth of C. japonica among cultivars. A correlation was observed between tree growth and leaf nitrogen concentration among the cultivars.
