VARIABILITY IN STATIC BENDING STRENGTH OF THE "TABÓRZ" SCOTS PINE WOOD (PINUS SYLVESTRIS L.).

The paper presents the results of research on variability in the static bending strength of the "Tabórz" Scots pine wood (Pinus sylvestris L). The wood samples for examination were obtained from the trunks of 260-year-old Scots pines felled in the "Sosny Taborskie " Nature Reserve. The mean value for all the tested wood samples amounted to 77.3 MPa, whereas for the individual trunks it reached 105.3 MPa, 66.4 MPa and 60.1 MPa, respectively. It is believed that the research results presented here are the first empirical data published concerning the mechanical properties of the wood of the "Tabórz" Scots pine, the trunks of which, due to their high quality, are considered in Europe to be extremely valuable timber.
