Radial Variation of basic density of the wood of Eucalyptus grandis W. Hill ex Maiden

Abstract

This study was undertaken to determine the radial variation of basic density of the wood of 14 years old Eucalyptus grandis W. Hill ex Maiden stands, located in the northern coast of Rio Grande do Sul. Thirty two trees were selected on the basis of the dominant and average diameter, and after cutting down, one disk was taken at breast height (DBH), for basic density determination in the radial direction. The results indicated that the basic density, both for dominant and average trees, presented lower values at the pith region (0,37g/cm³) increasing until the more peripheral region of the trunk (0,43g/cm³). No differences in basic density between dominant and average diameter trees were observed.
