The aim of this work was to analyze the tree−ring width, the share of the latewood as well as the density of wood of trees growing in commercial and degraded stands. The research was carried out in the Brynek Forest District (southern Poland) in 3 commercial stands and in 4 degraded stands. For every study plot fifteen spruces were chosen and increment cores were sampled using the Pressler borer....
The aim of the study was to compare the tree−ring width, latewood share and density of spruce wood from the mature stands occupying different forest habitats. 12 study plots were located in the north−eastern Norway spruce range in Poland (lowlands), whereas 16 in the south−western one (mountains). On the lowlands we chose stands growing on fresh mixed coniferous, humid mixed coniferous, fresh mixed...
The paper compares the properties of Norway spruce (Picea abies (L.) Karst.) wood from stands growing in the lower and upper subalpine forest zone in terms of the tree−ring width, the share of latewood and the wood density. The investigation concerned material originating from plots established within the boundaries of the south−western incidence of spruce in Poland. Plots were located in the Sudety...
