Aboveground biomass and net production rates in a young persimmon (Albizzia julibrissin) plantation (age after planting: 6 years) were studied with the litter trap method during a growth period in 1999 and by the clear-cutting method at the end of this period. The production rates of flowers, pollen, fruits, and flower and fruit stems were measured. Judging from the comparison of dry-matter production among young deciduous broadleaf and shade-intolerant tree communities, no striking characteristics of the A. julibrissin community were found. The permission showed features suggestive of invasion of shade- tolerant trees into pioneer tree communities, including low biomass density of aboveground parts (0.58 kg/m3), small leaf-mass (2.31 t/ha in dry matter and approximately 2.5 ha/ha in leaf area, at the end of October), and high relative light intensity on the ground (19%, on 25 October).
