All data were collected from Jaervselja and Kastre forest district. All model trees were divided into sections and experimental structures of the body were cut from each section. Research was carried out into 3 different growth classes (I-dominant, II-dominant and III-intermediate trees) and various heights of tree trunks (height 1,3m and the height of half the length of a stem). Spruce wood density was different in the case of all growth classes. It was highest in trees from the first growth class and the I and II growth classes were of lower density. Wood density was higher at the height of 1,3m and it reduced towards the bole
