<description lang=en>Few studies have investigated the influence of environmental conditions on the within-treevariation in Eucalyptus wood traits. The genotype and environment effects and their interactionsinfluence the wood properties. Their evaluations are crucial to estimate the genotype values andto select with efficiency. Thus, the aim of this study was to better understand the effect ofground slope and wind speed on the spatial variation of basic density (ρ), stiffness (MOE) andmicrofibril angle (MFA) of Eucalyptus wood. Wood discs cut along the trunk were sampledfrom 150 six-year-old Eucalyptus grandis x E. urophylla hybrids growing in 3 contrastinggrowing conditions influenced by ground slope and wind regime. Near Infrared (NIR)calibrations previously developed for ρ, MOE and MFA were used to predict in our discs. 2-Dplots presenting the spatial variation of predicted wood traits were compared. The higher theground slope, the greater the magnitude of radial variation in ρ, principally in the medium zoneof the trunk. The spatial variation of wood stiffness seems to be sensitive to two environmentalconditions. The MFA radial decreases were more pronounced where the wind speed was higher.At the base and top of the trees, however, there was no significant effect of growing conditionson the radial variation of the wood properties considered here.</description>
