Resumo: This work had as objective the characterization of the anatomical structure of the wood of two clones of Eucalyptus grandis x Eucalyptus urophylla, with approximately six years old that grown in two regions of the Minas Gerais state, with each region presenting two topographical combinations; plain and inclining. The behavior of clones was evaluated in the radial direction (variation pith to bark) and in the distinct conditions of growth. In the characterization of the wood it was determined specific gravity and dry density, the anatomical properties and fiber morphology. The results allow to observe that all the evaluated parameters had suffered variations between the conditions from plantation between clones and still variations in the radial direction. The results allow detailed characterization of the clones among topographya and regions, in which: (i) can be observed qualitative variations of the density, wood anatomical elements and fiber morphology between topographies, regions and clones; (ii) the radial variation of the density and the anatomical elements followed expected behavior for the specie where some parameters increase and others decrease in the pith to bark sense; (iii) the pattern of radial variation of density and quantitative parameters of the anatomical elements of wood, not presented significant differences among topographies, regions and clones. These results allow to understand the anatomical and physical behavior of the specie to the diverse conditions of growth and thus supplying subsidies to the pulp wood companies about consolidation of genetic material and its behavior in different conditions of growth to attend the wood quality requirement
