English title: Studies on annual variations of diameter growth of Scots pine in different parts of Finland.

Abstract

Discs were collected from sample trees of Scots pine (Pinus sylvestris L.) in different types of peatlands and mineral soil sites in Kajaani, Rovaniemi, Kuusamo; Suojärvi, Pielisjärvi, Evo and Lokalahti in Finland. The growth ring series of the different areas reach as far as in the 1600th century in some sample plots. The diameter growth shows patterns that repeat in cycles of 7, 11, 21, 35 and 70 years. However, the cycles are not exactly equally long. The average lengths of the cycles are relatively similar both in peatlands and in mineral soil sites.
