desorption strengthening - Opis:
- Analyses were conducted on wood from twelve Scots pines from northern Poland, aged 102 to 110 years, growing on former farmland and on forest grounds. The study was an attempt to determine basic density of wood, compressive strength along the grain, bending strength of absolutely dry wood and wood with moisture content above saturation point. Desorption strengthening was determined for analyzed strength properties of wood. Wood properties were determined in terms of juvenile and mature wood zones. Generally pines growing on former farmlands were characterized by wood with higher density and slightly lower strength than pines growing on typical forest soils. Conducted investigations indicate varied structure and properties of wood tissue formed in pines growing on former farmlands, which is different from that of typical forest soils.
