1983年,对自然分布区域内13个国家24个种源的苏格兰松(Pinus sylvestris L.)种子进行了播种。在苗圃的前3年中,测量和评估了一些性状,如高度生长和最上面轮生的小枝数。1986年春,在德国西南部本斯海姆林区进行了田间试验(3.3公顷)。在过去的几年中,测量和评估了以下性状:几个植被期后的高度生长,胸高直径,分支,茎形,甲虫的危害和死亡率。在这些性状方面,种源表现出相当大的差异,可分为至少6个主要群(群)。
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).
