Resumo(s)
Ring width and wood density variation were studied from pith-to-bark and along the stem
in two naturally regenerated stands of Quercus faginea Lam. in Portugal. Ring width was significantly
different between sites, in both heartwood and sapwood rings, ranging from 1.83 mm to 2.52 mm and
from 0.77 mm to 2.11 mm, respectively. Wood density was significantly different between sites only
in the heartwood, i.e., 914 kg m3 and 1037 kg m3. Site effects were the main source of variation for
ring width and wood density within the heartwood as well as for sapwood ring width, while the
between-tree effects explained more the density variation within the sapwood. Wood density showed
within-tree uniformity that was not affected by site. The stand characteristics such as basal area
and tree age may override the environmental growth conditions. There was also a weak correlation
between wood density and ring width components therefore suggesting the possibility of forestry
management for both fast tree growth and high wood density
