Resumo: | This study aimed to adjust volumetric models to tropical pines, in pure stand, in the municipality of Vilhena, Rondonia State.  The data came from 20 felled trees of Pinus caribaea var.  hondurensis and 10 Pinus tecunumanii trees with discs collected at fixed positions of 0.20 m, 0.70 m, 1.30 m and in distances of one meter along the stem, for later counting and measurement of the growth rings at ages from 4 to 12 years. Eight volumetric models were adjusted. The selection criteria used were: standard error of estimate, adjusted coefficient of  determination, F test, significance of regression coefficients,  mean deviation, standard deviation of the differences, sum of square of the relative residual, percentage of the residuals and graphic analysis of residuals. The models from Näslund  modified and from Spurr presented, respectively, best fit to estimate the volume for Pinus caribaea var. hondurensis submitted to the first thinning and for Pinus tecunumanii, with  ages between 4 and 12 years, in Vilhena, Rondonia State, Brazil.doi: 10.4336/2011.pfb.31.67.173
