Abstract
Influence of the environmental pollution degree on the chemical composition of wood and bark of Scots pine (Pinus sylvestris L.). Nine cca. 80-year old stems of Scots pine (Pinus sylvestris L.) were analyzed. They were gained from pine stems gained from the Ist, IInd and IIIrd zone of industrial damages (tree degradation). Disks of about 300 mm thick were cut from butt-end section, half height and top part of a stem. Samples from following zones were collected: sapwood, heartwood adjacent sapwood and heartwood. Measurements of annual rings width and late wood participation had been performed before samples for chemical analysis were collected. The results prove that the environmental pollution influence these quantities. It also impacts on the extractives content (decrease in bark from butt-end section), content (increase in bark) and distribution of 1% NaOH soluble substances (changes both on cross- and longitudinal sections), and lignin distribution on stems cross-section.
