English title: Development of mire originated Scots pine on mineral soil

Abstract

Scots pine (Pinus sylvestris) transplants (2+1+1 or 1+2 years old), the seeds of which had been collected from mire pines in different localities of South Finland, were planted in the early 1930s in a sandy Vaccinium site type at Tuusula (60°22´ N; 25°00´ E), north of Helsinki. The sample plots have been measured several times. At the time of the latest inventory the stands were about 50 years old. The stand development (standing volume, volume increment, dominant height, stem form) has been compared with the local mineral soil stands. The results show that seeds originated from mire pines produce offspring with form and growth (phenotypes) similar to those of pines originating from mineral soil.
