Abstract

Size, biomass and spatial distribution patterns of belowground woody organs ofPinus pumila trees were investigated. Dry weight estimates of five sample trees were between 14 and 36 kg tree−1. Belowground stems accounted for about 32% of the total tree weight. However, the belowground stems had extensive barkless portions, indicating that the decomposition of dead belowground stems was an important source of organic matter in the soil. The, basal diameters of adventitious roots tended to become smaller as their orginating positions neared the ground surface. It was suggested thatP. pumila trees regenerate by successively producing adventitious roots from their buried stems and moving down the slope.
