- Abstract
The distribution of pith, heartwood, and bark in timbers of four different Eucalyptus materials of seven years old, planted in three different spacings in the Midwest region of Brazil, were analyzed. Three trees were used for each of the three spacings (1058, 546, and 404 trees.ha-1) and for each of the four clones (three genetic materials of Eucalyptus urophylla x Eucalyptus grandis and one of Eucalyptus saligna), totaling 32 trees. Five discs extracted from each tree were analyzed to determine bark thickness, heartwood diameter, and pith displacement. Clones A and B (both from E. urophylla x E. grandis) showed the highest heartwood percentage and the thinnest bark, followed by genetic material D (E. saligna), which had the thickest bark, and C (E. urophylla x E. grandis), with the lowest heartwood percentage. Higher planting densities resulted in higher percentages, as well as thicker bark, with the exception of clone C of E. urophylla x E. grandis, which did not show higher amounts of heartwood regardless of planting density. The amount of heartwood up to 25% height remained constant for all clones, while bark thickness decreased from base to top. Regardless of genetic material, spacing between trees, and longitudinal position in the stem, there were no significant changes in pith eccentricity.
