Abstract
The form of dead bark in Scots pine (Pinus sylvestris L.) and selected biometric features and indicators. The paper attempts to define a relation between the values of some selected biometric features and indicators and the forms of dead bark in trees. Material for the study came from pure pine stands aged from 89 to 91 years, located in the Northern Poland. The analysis covered the following biometric features: diameter at breast height (DBH), area of sapwood (Sa) and heartwood (Ha) on the cross section of bolts at breast height, area of early wood (Eas) and late wood (Las) in the sapwood zone, mass of fresh needles (MFN), mass of fresh twigs with needles (MFT) and the following indicators: quotient of the sapwood and heartwood area, quotient of the early to late wood area in the sapwood zone and in the section of bolts at breast height. The obtained results show variations of the analyzed biometric features and indicators, not all of them being statistically significant.
