English title: Morphological study of Scots pine root system.

The root systems of 192 Scots pine (Pinus sylvestris L.) sample trees were dug out and measured in Säyneinen, Rautavaara and Pielijsäjvi in the Central Finland and Orivesi, Teisko and Hämeenkyrö in the Southern Finland. The volume of root system of Scots pine was always smaller than the stem, varying from 15% to 94% of the stem volume. The ratio is smaller in dense stands. The type of soil of the site affects how the central root system (tap root and the inner vertical roots) develop. This reflect the adaptability of the root system to different growth conditions. The root system may, for instance, substitute the tap root with stronger inner roots.
