Abstract: The present work aimed to evaluate the wood of fourteen genetic materials (nine species,
between native and exotic, and five clones of Eucalyptus) cultivated under two post-planting irrigation
regimes in the Brazilian semiarid region. For each genotype, six trees (11 years old) were selected
and subjected to two initial irrigation regimes (up to 12 months and up to 36 months) after planting.
Discs of different stem heights were taken: 0% (base), breast height (DBH), 20%, 40%, 60%, 80%, and
100%. Samples were extracted along the radial axis of each disk at three regions (the pith-adjacent
region, intermediate region, and bark-adjacent region). Samples were subsequently saturated in
water to determine their density via 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. Among the native species, Angico stood out with a high density and
little juvenile wood, and Pau d’arco, with a low density and a high rate of juvenile wood. Among the
exotic species, Nim presented a high density and a low rate of juvenile wood, and Chichá presented
a high rate of juvenile wood and a low density. In the Eucalyptus hybrids, VE38 stood out with a high
density. Overall, there was an influence from irrigation management, observed with greater intensity
in exotic species for Mahogany and Acacia and for the VE41 and AEC1528 clones of Eucalyptus. The
values of basic densities in the trees varied 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. MenosAbstract: The present work aimed to evaluate the wood of fourteen genetic materials (nine species,
