Resumo: | This work aimed to evaluate different taper models in the estimate of the merchantable height and volume and along the bole volumes of Eucalyptus sp., to the obtention of multiproducts. Considering the data of rigorous scaling of trees of Eucalyptus sp. with 16 years-old, it was appraised the models of taper of Demaerschalk (1972), Ormerod (1973), Schöepfer (1966), Hradetzky (1976), Garay (1979) and Biging (1984). Based on graphical analysis of the residues and on the statistics bias (B), average of the differences (MD) and deviation pattern of the differences (DPD), it could be verified that, in the estimate of the merchantable height and volume of the models, Biging, Schöepfer and Hradetzky presented the best results, followed by the models of Garay, which have also shown good results. In general, considering the treatment of the volumes of the logs, the Biging model presented the best resuts. |

Este trabalho teve como objetivo avaliar diferentes modelos de afilamento na estimativa da altura comercial, volume comercial e volumes ao longo do fuste de Eucalyptus sp. para a obtenção de multiprodutos. Com base em dados de cubagem rigorosa de árvores-amostras com idade de 16 anos, foram avaliados os modelos de afilamento de Demaerschalk (1972), Ormerod (1973), Schöepfer (1966), Hradetzky (1976), Garay (1979) e Biging (1984). Baseado na análise gráfica dos resíduos e nas estatísticas bias (B), média das diferenças (MD) e desvio-padrão das diferenças (DPD), verificou-se que, para estimativa da altura comercial e do volume comercial os modelos de Biging, Schöepfer e Hradetzky apresentaram os melhores resultados, acompanhados do modelo de Garay que apresentou melhora considerável para o volume comercial. De forma geral, nas condições estudadas, o modelo de Biging apresentou maior estabilidade na estimativa dos volumes ao longo do fuste.Universidade Federal de Santa Maria2008-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/45010.5902/19805098450Ciência Florestal; Vol. 18 No. 3 (2008); 387-399Ciência Florestal; v. 18 n. 3 (2008); 387-3991980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/450/346Souza, Carlos Alberto Martinelli deSilva, Gilson Fernandes daXavier, Alexandre CândidoMendonça, Adriano Ribeiro deAlmeida, André Quintão deinfo:eu-repo/semantics/openAccess2017-05-09T13:48:58Zoai:ojs.pkp.sfu.ca:article/450Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-09T13:48:58Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
