Abstract
The data has been collected during 1919 and 1920 in different region of Finland. The studied peatlands varied from fuscum pine swamps to pine swamps and partly to better sedge pine swamps.
The study presents five different forms of root systems. The root growth of pine on peatlands seems to vary strongly from the root form on mineral soils. On the peatlands, where the ground water near to soil cover is, can the roots grow only near the soil surface where the conditions are suitable. For the pine typical tap root is in most cases absent or grows along the soil surface. Also the frost heaving, snow and characteristics of peat affect the root system.
