Abstract

The objective of this work was to evaluate environmental effect on growth, wood basic density and anatomical characteristics of Eucalyptus grandis × Eucalyptus urophylla clones for pulp production. The studied clones were from 6.5-year-old plantations of Fibria Celulose company, located in two places: Nova Almeida (ES) and Posto da Mata (BA). The total and commercial heights, diameter at breast height (DBH), wood and bark volume (dendrometric characteristics), heartwood and sapwood percentages, wood basic density and wood fibers and vessels were evaluated. The heartwood and sapwood percentage and vessel frequency were the only characteristics not influenced by the growth site among the studied parameters. On the other hand, tree height (total and commercial) was considered the most influenced by the environment.
