ABSTRACT



The experiments were carried out on pine trees (Pinus sylvetris L.) growing in a seedlings seed orchard. Pine trees were pruned at the following terms: 25th April 1995, 14th July 1995 and 1st March 1996. Each time, trees were pruned (4 whorls of branches were removed) using the four different types of saws. Whereas wounds left after the removal of branches were treated with: emulsion paint, lack-balsam and Funaben and some wounds were left untreated for control purposes (zero treatment).

Key words: Scots pine, pruning, knot, wound cicatrisation, increment..
