The Decrease in Basic Density of Spruce (Picea abies /L./ Karst.) in the Past Thirty Years

Popis výsledku v původním jazyce

One of the most significant properties of wood is its density, which fundamentally affects its physical and mechanical properties. The most appropriate quantity for practical calculations in the forestry and wood processing industry is basic density, which allows a stock of wet wood to be converted to dry mass and vice versa. For the purposes of this research, thirteen spruce stands at the felling age were chosen in the Orlicke hory Mts. and the Slezske Beskydy Mts. (Silesian Beskids). In each stand, heartwood cores were extracted from 20 trees by means of the Pressler increment borer and their basic density was established. The cores were also used for the dendrochronological analysis of tree-ring width series. The resulting values of the basic density and tree-ring width were statistically processed and compared with the results of spruce basic density obtained in the research conducted in the 1970s. The comparison shows that the basic density of spruce, measured in the same altitudi
