Abstract : Wood is a very versatile material due to the variations of your intrinsic characteristics. Several use forms can be attributed to the wood that depending on your quality. Quality is a term that should be always associated to the use of the wood and it depends on your properties. In the studies of evaluation of the wood quality, they are usually certain the most important characteristics to have given use. This study aimed to evaluate the wood quality of Eucalyptus sp. clones to your bioenergy use. For this research four clones of Eucalyptus sp. were used. The clones were selected in a commercial planting with spacing 3.5 m x 2.5 m and 78 month years old, located in the State of Minas Gerais, Brazil. Wood characteristics as the basic density, elementary chemical analysis (CHN-O), extractive, Klason lignin (soluble, insoluble and total), ash content and calorific value (gross, inferior and net) were measurement. The used sampling was in obtained disks in five relative longitudinal positions (2%, 10%, 30%, 50% and 70%) of the commercial height of the tree, considered until a diameter of 5 cm. All the disks had about 2.5 cm of thickness. The chemical analyses and to gross calorific value was accomplished with a composed sample considering all the longitudinal positions. The results indicate that differentiates significant among the available genetic materials. All the clones present potential for bioenergy production. The clone 3281 presented higher ash content, lower basic density, lignin content and volumetric caloric value. The gross calorific value didn't differ significantly among the genetic materials.
