Characterization of wood of four forest species

This study aimed to characterize the microscopic anatomy and physical properties of wood from four different forest species. The wood has been studied from the following species: Cedrela fissilis, Crossbreed clone Eucalyptus urophylla × Eucalyptus grandis, Hovenia dulcis and Gallesia integrifolia. To determine the shrinkage it was used the standard of MB26/40 of ABNT (1940), the linear dimensions were obtained with palmer, accuracy of 0.001mm. The study of wood anatomy followed the recommendations of standard procedure in studies of anatomy of wood, COPANT (1974) and also the IAWA (1989). The anatomical characters evaluated were: tangential diameter (µm) and frequency of vessels (nomm-2), fiber length (µm), diameter of lumen (µm) and wall thickness of fiber (µm), height (µm), width (µm) and frequency of rays (nomm-1). The anisotropic factor values were of 1.17, 1.83, 1.89 and 1.90 for C. fissilis, H. dulcis, Crossbreed clone and G. integrifolia, respectively, showing that the C. fissilis wood has high stability dimensional and wood other acceptable values for this coefficient.
