Resumo: The aim of this study was to analyze the basic density of tree species of Cerradão phytophysiognomy in Cerrado domain in the state of Tocantins, and establish the relationship between the wood basic density of stems and branches. Samples of 80 trees were collected from stems (base, middle and top) and branches (thick branch, medium branch, and twig). The species had an average 0,650 g cm-3 of wood basic density. The basic density for most species (58%) decreased from the bottom to the top of the stem. The basic wood density between axial positions of the stem and the basic density of branches with different diameters showed significant relationship. According to proposed models to estimate stem density using branches density, the medium branch density showed the best adjust in the equation. The developed equations are adequate to estimate biomass and carbon stock of trees from Cerradão physiognomy, without destructive sampling.

Amostras de 80 indivíduos foram coletadas no tronco (base, meio e topo) e galhos (galho grosso, galho médio e galho fino) para determinação da densidade básica. As espécies apresentaram valor médio de 0,650 g cm-3, sendo que para a maioria das espécies (58%) decresceu da base para o topo do tronco. A densidade básica da madeira entre posições axiais do tronco e a densidade básica entre galhos de diferentes diâmetros apresentaram relação significativa. De acordo com os modelos propostos para estimar a densidade do tronco em função da densidade de galhos, a variável densidade do galho médio apresentou o melhor ajuste na equação. As equações desenvolvidas neste trabalho são adequadas para estimativas de biomassa e estoque de carbono de espécies arbóreas da fitofisionomia Cerradão, sem amostragem destrutiva de indivíduos arbóreos.Embrapa Florestas2015-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/82210.4336/2015.pfb.35.82.822Pesquisa Florestal Brasileira; v. 35 n. 82 (2015): abr./jun.; 63-75Pesquisa Florestal Brasileira; Vol. 35 No. 82 (2015): abr./jun.; 63-751983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/822/416Copyright (c) 2015 Carlos José da Silva, Ailton Teixeira do Vale, Eder Pereira Miguelhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSilva, Carlos José daVale, Ailton Teixeira doMiguel, Eder Pereira2017-04-28T12:44:45Zoai:pfb.cnpf.embrapa.br/pfb:article/822Revistahttps://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:2017-04-28T12:44:45Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
