Abstract

Above-ground and below-ground biomass allocation in important fuelwood trees from arid north-western India.

Abstract

Above-ground and below-ground biomass and its allocation pattern were studied in 6-yr-old trees of nine species, Acacia catechu, A. nilotica subsp. indica, Albizia lebbeck, Azadirachta indica, Dalbergia sissoo, Melia azedarach, Morus alba, Prosopis cineraria and Ziziphus mauritiana from arid NW India. Above-ground biomass (kg/tree) varied from 11.6 in Z. mauritiana to 37.5 in Melia azedarach. Maximum biomass (39-65%) was allocated to boles and a lesser amount to branches (22-40%) and roots (9-29%). Root biomass (kg/tree) ranged from 2.2 in A. catechu to 8.7 in Albizia lebbeck. Annual net primary production was 0.98 to 9.33 kg/tree across the species.
