Abstract

This paper presents the results of the adjustment of equations for estimating biomass of aerial compartments of Eucalyptus benthamii trees. The percentile allocation of biomass, in the compartments wood, bark, leaves and branches is also presented. The trees of Eucalyptus benthamii were sampled from stands of 12, 24, 36 and 48 months of age, planted at the spacing 3 m x 2 m, in the region of Guarapuava-PR. For the compartments considered, the generalized logarithmic model gave better indices of adjustment for branches and, together with logarithmic combined variable, the minor error for bark variable. Leaves and wood had minor error with model lnY=b0 +b1*lnDBH and logarithmic combined variable, respectively. The allocation of biomass in the different compartments was differentiated for each age. In the age of 12 months the greater percentile of biomass was in the leaves. However in the age of 48 months, wood had the greater percentage of biomass. The biomass allocation had the following ratios, respectively, for wood, bark, branches and leaves, 33, 3, 29 and 35% for the age of 24 months, 51, 5, 25 and 19% for the age of 24 months, 63, 5, 18 and 14% for the age of 36 months and 71, 7, 15 and 7% for the age of 48 months.
