Density and compression strength of Scots pine wood in relation to site and silvicultural measures

Popis výsledku v původním jazyce

The paper presents the results of an experimental research performed with Scots pine wood (Pinus sylvestris L.) coming from different areas in the Czech Republic - Doksy region and Plasy region. Although pine is the second most important commercial softwood species in the Czech Republic, we know very little about factors influencing its wood properties. We chose two different regions and subsequently forest stands with different history of silvicultural management inside these areas. Sample trees were cut to evaluate wood density and compression strength following Czech national standards. Besides site conditions, the silvicultural measures and position within a stem were evaluated factors influencing the tested properties. The biggest density value of 0,488 g.cm-3 was obtained in a stand that was regenerated using the shelterwood method with long regeneration period in Doksy region, and the lowest density value of 0,451 g.cm-3 was obtained in a stand that was regenerated using the clear-cutting method in Plasy region. The biggest value of 49,3 MPa for compression strength was achieved in Doksy region in the stand that was regenerated using the shelterwood method. On the contrary, the lowest value of compression strength of 43,1 MPa was achieved in Plasy region in a stand that was managed by the clear-cutting method. A growing trend for wood density and compression strength was confirmed in direction from the stem centre to the bark. It could be concluded that silvicultural measures, site conditions and within-stem position are important factors influencing quality of pine wood.
