The work was focused on problematics of annual-rings width according to position within the tree stem. Annual-ring widths, ratio of late wood and early wood by spruce with compression wood were investigated. Statistically significant differencies of individual zones in tree were occured. Zone of compression wood showed bigger width of annual-rings, common occurence of late wood and higher percentual ratio of late wood. Obtained results agree with common results in literature. Variability of annual-ring width according to position within the tree stem was confirmed. Width of annual-ring was changed mainly according to radius of stem. In height position within the stem no more significant variability of annual-ring width was observed.
