Abstract

This study was conducted to understand the biomass and the energy content of 36-year-old Pinus rigida stand planted in Mt. Taehwa, Gwangju-si, Gyeonggi-do, Korea. The total biomass of aboveground was 252.0 ton/ha (65.9% from stemwood, 8.9% from stembark, 20.6% from live branches, 1.5% from current leaves, 2.6% from previous leaves, and 0.5% from cones). Annual net production (ANP) of aboveground was 27.4 ton/ha/yr, and the ratio of stemwood, stembark, live branches, current leaves, and cones to ANP of aboveground total, 56.3%, 6.1%, 19.1%, 13.9%, and 4.6%, respectively. Energy content of aboveground was 5,434 GJ/ha, and annual energy accumulation was 597 GJ/ha/yr. Photosynthetic layer of P. rigida was shown at about 5.2 m in height, and maximum needle amount of crown at 11 to 13 m in height.
