Resumo: This study was carried out aiming to fit a volumetric model and a growth function, as well to comparethe growth of teak (Tectona grandis) in a stand located at Iracema (RR) with the growth of teak stands located at different areas in Brazil and Central America. To fit volumetric models 122 sample-trees were used and to fit a growth function to estimate DBH, medium and dominant height, and total volume without bark 18 sampletrees were used. The Chapman-Richards function was used and the data were obtained by stem analysis. The Schumacher-Hall model was selected to estimate total volume with bark of Tectona grandis trees. Chapman-Richards is a suitable function for determination of the growth curves for DBH, medium height, dominant height and total volume without bark. Comparison among dominant height growth curves on different sites indicated that the stand located in Roraima did not present good performance probably due to low soil fertility levels.

Para o ajuste dos modelos volumétricos, foram utilizadas 122 árvores-amostra, e para o ajuste da função de crescimento, 18. Os dados foram obtidos mediante a análise de tronco, e a função utilizada para estimar o crescimento em DAP, altura média, altura dominante e volume total sem casca foi a de Chapman-Richards. Como resultado, observou-se que o modelo de Schumacher-Hall foi o mais preciso para estimar o volume total com casca para árvores de T. grandis. A curva de crescimento em diâmetro, altura média, altura dominante e volume total sem casca foi determinada de forma satisfatória com o emprego da função de Chapman-Richards. A comparação entre curvas de crescimento em altura dominante em diferentes regiões indicou que o plantio localizado em Roraima não apresentou bom desempenho, provavelmente em virtude da baixa fertilidade do solo no local.Embrapa Florestas2010-02-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1110.4336/2009.pfb.59.05Pesquisa Florestal Brasileira; n. 59 (2009): jul./dez.; 05Pesquisa Florestal Brasileira; No. 59 (2009): jul./dez.; 051983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/11/39Copyright (c) 2010 Helio Tonini, Mirian Cristina Gomes Costa, Luiz Augusto Mello Scwengberhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessTonini, HelioCosta, Mirian Cristina GomesScwengber, Luiz Augusto Mello2017-04-28T14:06:04Zoai:pfb.cnpf.embrapa.br/pfb:article/11Revistahttps://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:2017-04-28T14:06:04Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
