Abstract

The aim of this study was to compare the accuracy of volume estimative along the stem of Tectona grandis L. f obtained by adjustment of non-segmented and segmented polynomial models, for a forest stand in South-Central region of Mato Grosso State, Brazil. Data from rigorous tree scaling of Tectona grandis, using One hundred and fourtheen trees were measured by Hohenadl method, using 16 sections. The non-segmented models tested were the fifth-degree proposed by Schöepfer in 1966 and the Haradetzky from 1976 model. The segmented models tested were the Max and Burkhart from 1976 and the Clark et al. from 1991. The models accuracy along the stem were evaluated by the deviation, the standard deviations of differences, sum of squares of relative residues and percentage of residues The fifth-degree equation is the most accurate to estimate the volumes along the stem of Tectona grandis, and Max and Burkhart equation accurately estimated the volumes of the stem basis.
