- The paper analyses the variability of selected adaptive, growth and morphological parameters of 16 Scots pine provenances from Poland. Their silvicultural value and usefulness under the growth conditions in Central Poland were assessed. The empirical part was carried out on the experimental plot established in spring 1966 in Lipce Reymontowskie Forest Range, Rogów Forest Experimental Station. In subsequent surveys, the following characteristics were determined for each tree: diameter at the breast height, height, height of crown base and diameter of branches. All trees were also classified into 4 quality classes related to the stem straightness. The following analyses were performed: survival rate, course of height growth and diameter increment over age, variation of volume at single trees and whole stands level, diameter of branches, stem straightness, selected genetics and silvicultural properties. The assessment of silvicultural values pointed out that the best provenances include Dłużek, Karsko, Bolewice and Rychtal. Local provenances from Rogów and Spała are classified as the weak ones. Therefore in local Scots pine stands there is a need to improve quality, stability and yield. Obtained results deepen an existing knowledge on variability of Scots pine stands and demonstrate possibilities for verification of seed regionalization principles in Poland.
