poland - Opis:
- The aim of the study was to determine the relationship between the quality of habitat and the quality of Scots pine wood. We focused on the wood from mature stands growing on poor habitats on inland dunes in the Notecka Forest and on former farmlands (central and western Poland). We selected 12 trees, from which we took wood samples for tree ring investigation. We determined the age of trees, width of increments, share of late− and hardwood, and the moisture and density of the wood. Samples were weighed with 0.001 g accuracy and their volume was determined with hydrostatic method. Next, samples were dried and their mass was determined again. The obtained results were used to calculate: initial and conventional wood density as well as moisture content of each sample. Properties of the examined wood derived both from Notecka Forest as well as from farmlands were advantageous from the point of view of its technical quality. Mean width of annual increments, both near−pith and near−circumferential, ranged from 1.70 to 1.99 mm and qualified analysed wood as the narrow−ringed. The examined wood characterised high proportion of latewood, close to the upper limit given in literature for standard conifer wood and by high density. Mean share of latewood in the near−pith increments ranged from 18.9 to 30.6%, while in near−circumferential increments – from 34.3 to 45.7%. The highest average conventional density amounted to 507 kg/m³, whereas the lowest – to 466 kg/m³. The obtained results revealed that the wood from the Notecka Forest had favorable properties in terms of technical quality. It had the characteristics of slow−grown wood and was characterized by a high proportion of latewood in annual increments and a conventional density higher than the one reported in the literature.
