- Abstract
The objective of this study was to determine the capacity of the aboveground biomass of forest species: Acacia mearnsii De Wild, Eucalyptus grandis W. Hill ex Maiden, Mimosa scabrella Benth and Ateleia glazioviana Baill distributed in different spacing in planting: 2.0 x 1.0 m, 2.0 x 1.5 m, 3.0 x 1.0 m and 3.0 x 1.5 m, at ages of 1 and 3 years. This work was performed in an experiment using a randomized complete block design characterized by a 4x4x2 factorial in three replicates, conducted in the city of Frederico Westphalen-RS. The determination of the biomass consisted of cutting and weighing the different compartments of the trees. For the wood and bark were removed discs 2.0 cm in thickness in the stem positions: 0% (base), 25%, 50%, 75% and 100% of the total height. As for branch and leaf biomass, stratified samples were taken and determined its final weight. Increased planting density showed a direct relationship with the biomass production per unit area in different years of assessment. The highest biomass production was observed in the narrower spacing plant and concentrated mainly on the trunk and branches of trees. The species that stood out were Eucalyptus grandis and Acacia mearnsii. Already Ateleia glazioviana had the lowest biomass production per unit area. [ABSTRACT FROM AUTHOR]
