Allocation of Wood Density in European Oak (Quercus robur L.) Trees Grown under a Canopy of Scots Pine

The allocation of wood density in trees depends on many factors, but mainly the tree species. A great number studies have analysed dominant or codominant trees, only a few focused grown under canopy. We examined basic and fresh natural origin oaks growing canopy artificially planted Scots pine. major purpose work was to study different parts such as trunk branches. From total 80 we selected eight model measured biometric features their trunks crowns. Wood samples from crown were collected after felled. observed significant differences between average (595 kg·m?3) (1031 kg·m?3). central part heartwood shows much higher than outer sapwood, which corresponds ring-porous trees. Both types (basic fresh) also branches differed two zones: A1, closer had density; A2, farther away with lower density. positive correlation length not width, more connected diameter at breast height. found value slenderness reported by other authors without is associated potential mechanical load.
