The paper deals with the variability of tree-ring width, with the density and swelling (volumetric swelling and swelling in individual anatomical directions) of wood from two different locations. Further, the variability of the explored properties along the stem radius is researched. The ring analyses show that the ring width decreases along the stem radius from the pith to the stem outer perimeter. Location 2 (a lower altitudinal vegetation zone) had on average wider rings (a statistically insignificant difference), higher density and higher volumetric swelling of wood in comparison with location 1 (a statistically significant difference). The relation between volumetric swelling and wood density has been confirmed. The results show that the wood density and its volumetric swelling change along the stem radius. With the increasing wood density the volumetric swelling also increases. The average density of beech wood from both locations is 752 kg/m3 with moisture content of 12%.
