Anatomical studies were conducted,chemical, basic density and sapwood/heartwood relationship of wood.
The basic density of the wood is important for characterizing the material as it is directly related to its quality.
The characteristics evaluated in the wood were higher heating value, basic density and elemental and structural chemical composition.
The wood basic density values for each species obtained in the literature was multiplied by the volume to estimate wood biomass for each species.
The physical characteristics of the wood were analyzed using standard nbr 11941 and nbr 7190 for basic density and moisture, respectively.
The dendrometric parameters,anatomical parameters, the basic density and chemical composition of wood were influenced by the inclination of the trunk.
We also verified if the longitudinal diameter at breast(dbh)sampling may be used as a reference to estimate the average basic density of the tree.
The following wood properties were analyzed: basic density; extractive, ash, and carbohydrate(monomeric sugars, cellulose, hemicelluloses) contents; and uronic acids. the pulps w.
The independent variables also affected bleached pulp coarseness while wood basic density affected the fiber width and lumen diameter.
The aim this study was to estimate the average basic density of tree species from a sample of branches in order to maintain the integrity of the trunk and allowing estimation of dry biomass.
