| Abstract | ||
| Simple regression was used to obtain a mathematical equations for estimating the total stemwood density in three species of forest tree, namely: Pinus brutia Ten, Casuarina equestifolia, and Eualyptus Camaldulensis Dehn; by connecting the total stemwood density in its orginal form as dependent variable with the density values at breast height. A sample of 44 Pine trees, 34 Casuarina and 32 eucalyptes were used in this study. An equation was obtained for each type of wood characterized by having a very high R2 and a low S.E.% which confirmed the high accuracy of the obtained equations, the equation are: | ||
