The study objectives included: i) determination of the mass and green density of pulpwood (wood+bark) and ii) comparison of the changes in these parameters during 14−day−long storage period. The experiment was conducted between 15 and 28 July 2014 and the material was taken from the 67 year−old Scots pine stand (Tuchola Forest District, northern Poland). Using the Urich method, 30 model trees were...
Research was carried out in Scots pine (Pinus sylvestris L.) stands damaged by strong wind in six locations in Poland. The aim of this study was to analyse the radial variation of compressive strength parallel to grain in the wind−broken trees and neighbouring survivors. Strength tests were conducted in moisture above saturation fibre point. There were no significant differences in the radial distribution...
The aim of the study was to determine the effect of selected tree stability indices described by individual biometric characteristics on the formation of their wind resistance. The analysis of tree stability was based on easily measurable tree traits, such as height, breast height diameter, crown parameters as well as the centre of gravity and slenderness factor. Investigations were conducted in wind−damaged...
We assumed that wood of trees undamaged by wind will be characterized by higher basic density than wood of damaged specimens. It was stated that wood of windthrow had lower basic density, but differences were not statistically significant. Two parts of wood: (compressed and tensioned zones) were analyzed separately. Higher density was found in tensioned zone of windthrow and in compressed zone in...
