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.

Para a coleta de dados, foram derrubadas 20  árvores de Pinus caribaea var. hondurensis e 10 de Pinus  tecunumanii, sendo coletados discos em posições fixas de 0,20  m; 0,70 m; 1,30 m e em distâncias de um metro ao longo do  fuste, para a posterior contagem e mensuração dos anéis de crescimento nas idades de 4 a 12 anos. Foram ajustados oito modelos volumétricos e o critério de seleção considerou os  resultados do erro padrão da estimativa, coeficiente de determinação ajustado, teste F, significância dos coeficientes de regressão, desvio médio, desvio-padrão das diferenças, soma de quadrados do resíduo relativo, resíduo percentual e a análise  ráfica dos resíduos. Os modelos de Näslund modificado e Spurr apresentaram, respectivamente, o melhor ajuste para a estimativa do volume nos povoamentos de Pinus caribaea var. hondurensis, submetido ao primeiro desbaste, e Pinus  tecunumanii, com idades entre 4 e 12 anos, em Vilhena, RO.Embrapa Florestas2011-08-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/27010.4336/2011.pfb.31.67.173Pesquisa Florestal Brasileira; v. 31 n. 67 (2011): jul./set.; 173Pesquisa Florestal Brasileira; Vol. 31 No. 67 (2011): jul./set.; 1731983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/270/1638Copyright (c) 2011 Allan Libanio Pelissari, Luciano Rodrigo Lanssanova, Ronaldo Drescherhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessPelissari, Allan LibanioLanssanova, Luciano RodrigoDrescher, Ronaldo2017-04-28T13:06:26Zoai:pfb.cnpf.embrapa.br/pfb:article/270Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T13:06:26Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
