Abstract

Biomass, energy content and fuel-wood properties of certain clones of Populus deltoides were studied. Out of 15 clones tried, the performance of St.-148, D-121, S7C15, St-163, G3 and G48 was reasonably good in terms of growth, basal area and survival percentage. Stand biomass, estimated from two forms of regression equations indicated that the allometric equation with dbh as ‘x’ variable was equally good to that of linear equation with d2h as ‘x’ which requires an additional measurement of plants height. There was no significant variation in r2 when the sample size increased from 21 to 161 plants to develop an allometric equation. Total biomass of the above promising clones varied from 23.7 (G48) to 42.8 (St-148) t ha in 2 years which constituted 600 to 1056 Gjha1 energy content in their standing stock. The usable energy content which includes the stem, branch and twigs, consisted of 79 to 86% of the total energy storage in the plants. The fuel-wood properties of St-163 clone showed the lowest moisture content (42%) and highest wood density (0.48 g/cm3) and carbon content (36%) among the clones studied. However, G3 clone showed highest energy value (28.7 kJg-1). The concentrations of ash, silica and nitrogen were lowest for S7C15 clone which is generally preferred for a good duel-wood quality. The fuel value index > 100 for the said promising clones confirms their suitability for energy plantation programmes in the present habitat.
