Variability Properties of Pinus sylvestris L. Wood in Growing Stock under Technogenic Impact

Journal Title: Lesnoy Zhurnal (Russian Forestry Journal) - Year 2020, Vol 10, Issue 4

Abstract

The issues of variability of pinewood (Pinus sylvestris L.) properties in growing stock located in the vicinity of operating industrial facilities is still relevant. The paper aims to assess the technogenic impact on the radial increment as well as the physical and mechanical properties of pinewood in the conditions of Northern Taiga. The impact of the distance from the source of emissions on variability of the radial increment and the volume and technical properties of wood were determined. Distribution maps of the conventional wood density and its compressive strength along the fibers inside the trunk were formed. It is found that with a decrease in the distance from the source of emissions, the average value of the radial increment of trees occurs. It is revealed that there is a decrease in wood density from the butt to the top, and from the pith to the sapwood. Also, it is determined that wood density increases as the distance to the source of emissions decreases. However, there were obtained no valid differences of the indicator of wood resistance to compression along the fibers at various distances from to the source of emissions.
