- Influence of section lengths on volume determination in eucalyptus trees Carlos Pedro Boechat Soares Gilson Fernandes da Silva Fabrina Bolzan Martins Agrociencias Smalian formula Eucalyptus grandis Volumetric equations 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. 2010 artículo científico 0104-7760 https://www.redalyc.org/articulo.oa?id=74421665005 en http://www.redalyc.org/revista.oa?id=744 CERNE application/pdf Universidade Federal de Lavras CERNE (Brasil) Num.2 Vol.16
