Resumo
The objective of this study was to determine the technological properties of the wood of Khaya ivorensis and Khaya senegasensis (African mahogany) in trees with 19 years old, from the Vale Nature Reserve, Espírito Santo. The characterization of African mahogany woods was by anatomic description, determination of physical and mechanical properties, analysis of extractives, evaluation of natural resistance of, wood decay organisms (white rot fungi, brown and soft and dry wood termites and subterranean termite) under laboratory conditions, studying the behavior of the accession of wood. On the anatomical description, there were differences between species. The timber of Khaya ivorensis was classified as a low density wood, and the wood of Khaya senegalensis was classified as medium density wood. Both species with medium dimensional stability. The timber of Khaya senegalensis was mechanically more resistant in all the tests. The wood of Khaya ivorensis was more resistance to attack by white rot fungi and wood of Khaya senegalensis was more resistant to fungal attack of brown and soft rot and dry wood termites and subterranean termite. Both species of African mahogany not obtained satisfactory results in the tests for accession.
