Abstract The paper presents the results of investigations carried out on the experimental plot which was established in 1914 by professor Busse from Tharandt. The objective of the experiment was to determine the age of maternal trees on the growth and development of progeny stands. The study describes the course of investigations as well as the results obtained during the consecutive periods. The presented results refer to seven provenances of Scots pine derived from the stands of the following forest districts: Zielonka, Bolewice and Brójce. The experimental surface was established on the Trzciel Forest District in Poland. Busse’s principal methodological assumption was to employ in his experiment seeds of trees of different age (16 to 170 years old). The presented paper discussed the results obtained during the period from 1965 to 2006. Two provenance groups were identified on the basis of statistical differences and similarities: older maternal stands – more favourable characters of progeny growth and development: IV, V, VI (101-170 years of age) and younger maternal stands – less favourable characters of progeny growth and development: I, IIb, III (16-80 years of age).
