The highest slenderness coefficient values were noted for trees growing in the widest spacing variants. In the untended stands, the initial density affected tree height and crown length. 40, both in the tended and untended stands. The study pointed to a significant impact of initial density on stem diameter of pines aged c. Initial densities from 4,630 seedlings/ha to 15,625 seedlings/ha were subject to analysis. The study focuses on the effect of initial density on the development of untended stands and of those in which improvement cuttings were applied. The objective of this study is to determine the effect of initial density of Scots pine trees on their growth parameters, silvicultural value and stability, as well as to evaluate the possibility of breeding selection in pine stands varying in initial densities.
