Conteúdo: | This study aimed to verify the influence of plant spacing and cutting age to estimate the dry mass of wood without bark, carbon mass and energy per hectare, compared to the average annual increment of a hybrid of Eucalyptus grandis x Eucalyptus camaldulensis. The experiment was installed in December 2002 and were evaluated five different spacings, 3,0 x 0,.5; 3,0 x 1,0; 3,0 x 1,5; 3,0 x 2,0 and 3,0 x 3,0 meters. Measurements were carried out at 4, 5, 6 and 7 years old. For each tree were removed discs at the base, 25, 50, 75 and 100% of the commercial trunk height. The amount of energy per hectare was calculated on the basis of the values of the IMA, basic density, calorific value of wood and the carbon mass. The results show that for the production of charcoal and energy optimal crop age is 5 years spaced by 3,0 x 0,5 meters, which shows that the use of high planting density and short rotation, for this order, based on the properties of the produced timber, was satisfactory.
