Tree-ring widths and wood density variability of non-native species: a case study of Douglas-fir growing in central Europe

Popis výsledku v původním jazyce

The aim of the present study was to analyze the wood density variations along the stem radius of non-native Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) growing in Central Europe. Sample logs (0.5 m; breast height) were obtained from five Douglas-fir trees growing in the Czech Republic, to analyse the tree-ring widths (TRW) and the oven-dry wood density intra-species variability. The first 15 tree rings (close to the pith) were found to be 5.14 +- 1.68 mm wide, while the average TRW gradually decreased. The average oven-dry density of wood produced by non-native Douglas fir growing in the Czech forest was 542.9 +- 66.3 kg m-3, which is notably higher than the home-grown Douglas-fir wood. Along the stem radius, from pith to bark, oven-dry wood density showed an upward trend.
