Abstract
The possibility of biomass production was studied in an experimental trial stand with four clones of Eastern cottonwood Populus deltoides Bartr. ex Marsh. cl.457, cl.450, cl.618 and cl. 55/65 and three stand densities a) 1.2 × 1.0 m (8330 plants·ha–1), b) 1.2 × 0.75 m (11110 plants·ha–1) and c) 1.2 × 0.5 m (16600 plants·ha–1). Field trials were conducted on sandy-loamy form of fluvisol.
Total determined volume of trunk, bark, and branches in the first two-year cycle for the used Eastern cottonwood ranged from 27.391 m3·ha–1 in clone 450 at planting distance of 1.2 × 1.0 m, subtreatment (a) to 42.006 m3·ha–1 in clone 618, subtreatment (c) at planting distance of 1.2 × 0.5 m. After renovation of stand using the regeneration force of shoots from the tree stumps the produced wood mass in the second two-year cycle ranged from 54.664 m3·ha–1 in clone 55/65, subtreatment (a) to 79.235 m3·ha–1 in clone 450, subtreatment (b).
In additon to clone selection a significant influence on biomass yeald was also exerted by stand density (number of plants·ha–1).
The largest amount of heat energy would be obtained in subtreatment (c) at density of 1.20 × 0.5 m by combustion of biomass of above ground part of clone 55/65: 364.02 GJ·ha–1 in the first cycle, and 659.83 GJ·ha–1 in the second, or a total of 1023.85 GJ·ha–1.
