wood defects - Opis:
- Knots are remnants of branches left on the stem or visible in the side of the tree. They affect wood quality and its final utilisation. The rate of self−pruning depends on many factors, including tree species. The balance of assimilation and disassimilation to a considerable degree determines natural clearance of branches. The aim of the study was to determine the dynamics of natural clearance of branches in European larch (Larix decidua Mill.) varying in breast height diameter and height. Analyses were conducted in stands of different age classes. After mean sample trees were felled (selected according to Urich I) macroscopic observations were conducted, classifying individual zones of the stem into separate classes according to the rate of self−pruning. Analysed traits were found to vary considerably. A strong relationship was shown between breast height diameter, tree height and the length of the knot−free zone. The crown of the analysed forest−forming species retains similar relative length throughout the life of a tree.
