English title: On the seasonal changes of root system of a pine stands on the peatlands.
Original keywords: Kiefer; Moor; Wurzelverhältnis; Jahreszeit

The seasonal changes of the roots systems of a pine stand on the peatlands have been studied with samples collected during summers 1952-1954 and winter 1955. There are altogether seven sample areas that are located in the district of Korkeakoski.  

The amount of roots is at the smallest in the spring, increasing then rapidly and peaking at the end of July. After that the amount of roots decreases again against the winter to the same size than in the spring. Variations seem to be similar in every year and also similar to other studies on mineral soils.

The PDF contains a summary in Finnish.

English title: Variations of the root systems of a pine stand during the growing period.

The article presents the results of the studies about the horizontal root systems of pine. The results have been obtained with the method developed by the author.

The size of the root system varies very strongly during the growing period. The amount of roots is at the smallest in the spring, increasing then rapidly and peaking at the end of July. After that the amount of roots decreases again against the winter to the same size than in the spring. The differences are due the changes in the amount of the smallest roots. There seem to be no big differences in the amount of roots between stand of different ages.

After the thinning there is a drop in the amount of roots on the stand level, but after two growing periods then standing trees have taken over the unused land. However after selection felling the less vital trees are not capable of utilizing the vacant resource as effectively.
