Resumo: The precise estimate of the volume of a forest stand become important as forest enterprises integrate vertically their activities and the residue of the manufacture of a product becomes the raw material for the manufacture of other. The accomplished studies aimed to evaluate the accuracy of the polynomial models proposed by Schöepfer (1966), Hradetzky (1976) and Goulding & Murray (1976) in the estimate of the diameters and volumes along the bole of Tectona grandis L.f from four stands situated in the Baixo Rio Acre micro region and further, to test the identity of the best polynomial model by evaluating the adequacy of maintaining the grouped areas or segregate them into smaller groups or singly. The data base was made up of 159 trees scaled rigorously. In the evaluation of the accuracy of the models, the statistics of average deviation, standard deviation of differences, square summation of relative residue and percent residue. The Goulding & Murray (1976) model was generated the best estimates of diameters and volume along the bole, followed by the models of Hradetzky (1976) and Schöepfer (1966). The model identity test proved more adequate to perform independent fit for areas 1 and 4 and for subgroup 2 and 3.
