Wood macrostructure of Norway spruce (Picea abies [L.] Karst) coming from an experimental site in the Siemianice Forest Experimental Station. The paper presents results of studies concerning the effect of provenance on the share of latewood in annual rings. Analyses were conducted on seven provenances grown on an experimental site located in the Siemianice Forest Experimental Station. It was established which of the investigated provenances have the greatest share of latewood in annual rings. It was also investigated which of the provenances differ significantly in terms of the analysed trait. Measurements were taken on discs collected from breast height of mean sample trees.
