The study is an attempt to determine the relationship between selected biometric traits of Scots pine trees (Pinus sylvestris L.) grown in conditions of forest and former farmland and macrostructural elements of their wood. The obtained results confirm that there is a strong correlation between these traits. This strong correlation allows, on the basis of biometric traits, especially of the breast height diameter, to draw conclusions about the proportion of sapwood and heartwood in the stems of Scots pine trees. The undertaken problem does not explain all correlations that exist between wood macrostructure and wood biometric traits and fails to answer a number of questions associated with the quality of wood raw material derived from land formerly utilised as arable land. It is, therefore, desirable to continue investigations in this area.
