This research aim to evaluate the wood and charcoal quality of three Eucalyptus clones planted at different places and to verify the existent functional relations between the basic density and the depth of penetration of the Pilodyn pin. Three Eucalyptus clones were evaluated and four trees were sample for each clone and place. It was determined the depth of penetration of a Pilodyn pin at 1.30 m of height of the soil (DBH), average basic density (DBm), the basic density at DBH, the calorific value, lignin, total extractive, ashes and holocellulose contents and elemental chemical analysis (C, H, N and O). The wood was carbonized and the charcoal produced was evaluated quantitatively and qualitatively. In the evaluation of the wood characteristics a completely randomized design disposed in a factorial scheme 3 x 2 was used. A linear model was adjusted between DBm and the depth of penetration of the Pilodyn pin. It was possible to conclude that the clones present potential to be used for energy. The charcoal produced may be used in siderurgy. The linear model adjusted between DBm and the penetration of the Pilodyn pin was satisfactory.doi: 10.4336/2011.pfb.31.68.319
