Abstract. Analyses were conducted on wood of Scots pines collected from timber stands growing on post-agricultural land and forest land in the fresh coniferous (Bśw) and fresh mixed coniferous (BMśw) forest habitats located in the territory of the Miastko Forest District.
The wood of pines growing on post-agricultural land in the BMśw habitat conditions had the highest basic density and lowest compression strength along the grain among the tested sample groups. The arrangement of wood properties was not typical with regard to the social position of trees in a stand. The obtained results have shown the lack of a direct relationship between wood basic density and compression strength along the grain. The analyses performed pointed to differences in the properties of wood tissues between pines growing on post-agricultural land and pines growing on typical forest soils.

Key words: wood quality, basic density of wood, compression along the grain, desorption strengthening.
