SUMMARY:
This study aimed to evaluate the wood quality of fourteen genetic materials (nine species, including native and exotic, and five clones of Eucalyptus), cultivated under two regimes of post-planting irrigation in the Brazilian semi-arid region. For each genotype, six trees were selected, submitted to two initial irrigation regimes (up to 12 months; up to 36 months), both after planting at an age of approximately 11 years. For the analysis, discs were taken from different heights of the stem: 0% (base), breast height (DBH), 20%, 40%, 60%, 80% and 100%. Disc subsamples in the radial positions close to the pith, intermediate and close to the bark were also collected and saturated in water to perform the density determination, established by the water displacement method. The irrigation systems caused changes in the pattern of radial and longitudinal variation in the clones regarding the proportion of woody material in the stem. The values of the basic densities in the trees ranged from 0.35 to 0.85 g.cm-3. There was good adaptation of native and exotic species and clones to the planting area in the semiarid region.
