Results of the IUFRO 1982 Scots pine (Pinus sylvestris L.) provenance experiment in southwestern Germany
1996
Stephan, B.R. | Liesebach, M.
Seed of 24 provenances of Scots pine (Pinus sylvestris L.) from 13 countries within the area of natural distribution was sown in 1983. During the first 3 years in the nursery several traits were measured and assessed, e.g. height growth and the number of twigs in the uppermost whorl. In spring 1986 a field trial (3.3 ha) has been established in forest district of Bensheim, southwestern Germany. During the last years the following traits were measured and assessed: height growth after several vegetation periods, diameter at breast height, branching, stem form, damage by the beetle Brachyderes incanus and mortality. Regarding these characters the provenances show a considerable variation and can be divided into at least 6 main groups (clusters).
