The objective of this study was to investigate the
altitudinal variation within and between Scots pine (Pinus
sylvestris L.) populations in Turkey using 23
morphological characters. Seeds were collected from 149
open-pollinated parents (trees) from five populations
sampled from different altitudes in the natural distribution
range of the species in northern Turkey and raised in a
nursery along the coast. The populations were compared based
on phenotypic variation of cones, seeds, seed-wings,
juvenile seedlings and seedlings morphology, to study the
pattern of natural variation of the species. ANOVA and
Duncan test showed that the morphological characters
differed by populations. Also, the cluster modeling
performed on the morphological characters suggested that
altitude was a major factor to differentiate the groups.
This study showed that there were significant differences
within and between the populations in P. sylvestris
for the morphologic characters studied.
