【 摘 要 】

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.
