Spruce timber quality in trees with different thickness from the Beskidy Mts

Abstract An advancing process of ageing of stands in Poland and Europe allows for predicting and increasing in the supply of large-dimension timber. The research compares selected qualitative characteristics of the timber of trees with large breast-height diameters (equal to or larger than 40 cm) with those of thinner trees on the example of Norway spruce from the region of the Beskidy Mts. A group of thicker spruce trees was characterized by a higher overall share of trees with wood defects, including visible knots and symptoms of overgrown knots as well as a smaller share of trees with injuries, rot and curvatures in comparison with the thinner ones. The absolute size of rot on the cross-section of the stem was larger in thicker trees. They were also characterized by a smaller average width of annual rings. The groups compared did not differ significantly as to the height of location of defects situated as first from the stem base.
Keywords: spruce timber, thicker and thinner trees, timber defects
