Resumo: The aim of this work was to assess the influence of different section lengths on the determination of eucalyptus tree stem (with bark) volumes and its implications in forest inventory procedures. The 40 Eucalyptus grandis trees used, all from the municipality of Viçosa, Minas Gerais state, were 77 months old. The volume of the stems (with bark), whose maximum diameter was 3,0 cm, was obtained through the Smalian formula, with sections 1.0, 2.0 and 3.0 m long. Longer sections lead to overestimations of the volume of the trees’ basal part and, consequently, of their total volume. Different statistical tests led to different conclusions regarding the similar volume estimates resulting from experiments using different section lengths4. Volumetric equations adjusted with longer sections may introduce bias errors in forest inventory procedures.

Para isso, foram utilizados dados de 40 árvores de Eucalyptus grandis, com 77 meses de idade, obtidos no município de Viçosa, Minas Gerais. Os volumes dos fustes com casca até um diâmetro limite igual a 3,0 cm foram obtidos utilizando-se a fórmula de Smalian, considerando seções de 1, 2 e 3 metros de comprimento. O aumento do comprimento das seções causa superestimativas dos volumes na parte basal das árvores e, consequentemente, dos volumes totais das árvores. Testes estatísticos distintos resultaram em conclusões diferentes quanto à igualdade das estimativas dos volumes obtidos com diferentes comprimentos de seções. Equações volumétricas ajustadas com seções de comprimentos maiores podem introduzir erros de tendência nos procedimentos de inventário florestal.CERNE2015-05-152017-08-01T20:14:23Z2017-08-01T20:14:23Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttp://www.cerne.ufla.br/site/index.php/CERNE/article/view/151SOARES, C.
