The wood anatomy of 7 species from the Brazilian Amazon forest was studied to evaluate them for energy production (charcoal and alcohol) and for paper production. Transverse. For paper production, the wood was qualified according to the coefficient of rigidity and flexibility, density, Runkel index, the percent of fibers, vessel, axial parenchyma and percent of area occupied by rays. For energy production, wall fraction in relation to the area occupied by cells (%), percent of fibers, vessel, and both axial and ray parenchyma, as well as wall density were considered. The study was based on 3 areas of the cross section of the trunk, from the center towards the sapwood. On the basis of anatomy and density, Bellucia grossularioides, Cecropia palmata, Duguetia cauliflora, Eschweilera matamata and Parkia multijuga can be used for pulp for paper production, and Myrocarpus frondosus, Sloanea grandis can be used for charcoal production.
