Resumo: | Essentially there are three methods for commercial volume estimation of single trees namely: the use of a form quotient, volume equations and taper functions,which produce different results in variable precision and must be used adequately for different objectives. The aim of this study was to compare these methods. So, trees of Eucalyptus grandis from a first thinning were measured. The use of volume equations of two independent variables was the most effective method for commercial volume estimation. The use of form quotient has shown to be restricted and, taper functions have proven to be efficient to determinate the multiple uses of a tree. |

A comparação entre estes três métodos foi o objetivo desta pesquisa e, para tanto, foram medidas árvores de Eucalyptus grandis provenientes de primeiro desbaste. A utilização de equação de dupla entrada foi o método mais eficiente para a determinação do volume. O uso do fator de forma se mostrou restrito e as funções de afilamento foram eficientes para elaboração de tabelas de sortimento.Embrapa Florestas2013-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/ziphttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/44610.4336/2013.pfb.33.73.446Pesquisa Florestal Brasileira; v. 33 n. 73 (2013): jan./mar.; 1-7Pesquisa Florestal Brasileira; Vol. 33 No. 73 (2013): jan./mar.; 1-71983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/446/pdf_32https://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/446/1131Schröder, ThomasHofiço, Noé Ananias dos SantosZimmermann, Anna Paula LoraPereira, Lílian DanielRocha Junior, Dilson SousaMeyer, Evandro AlcirFleig, Frederico Dimasinfo:eu-repo/semantics/openAccess2017-04-28T12:53:59Zoai:pfb.cnpf.embrapa.br/pfb:article/446Revistahttps://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:2017-04-28T12:53:59Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
