The rychtal pine is one of the most valuable ecotypes of Scots pine (Pinus sylvestris L.) approved for the breeding purposes in Poland. However, it occupies stands typical for oaks and beeches as shown by the compatibility analysis of species composition in relation to the habitat type in which they occur. Such result raises some doubts in terms of the naturalness of the rychtal pine and calls its...
In forestry management, artificially produced planting material is mainly used for renewal the tree population. Seedlings are cultivated in two systems: in the ground (the bare−root seedlings) and in controlled conditions (container seedlings). The aim of the study was to analyse the microsatellite markers of nuclear and chloroplast DNA, in terms of the number and frequency of rare, private, low frequency...
The production of forest tree species in forest nurseries is performed via two main breeding systems: i) the traditional (conventional) way with the seedlings grown in soil, and ii) plants cultivated in the containers. The aim of the study was to assess the level of genetic variability in the populations of the mother stands and the progeny populations of Scots pine cultured with traditional way (in...
We looked at the patterns of differentiation at a set of phenotypic traits of Scots pine populations derived from different environmental conditions of the species distribution range in Poland. The growth traits were tested over 47 years at the provenance trial experiment in the Carpathians. The phenotypic differentiation of the populations was compared to diversity estimates at a set of ten nuclear...
Adaptation to local environmental gradients is one of main characteristics of living organisms. Scots pine (Pinus sylvestris L.) is the most widely distributed conifer in the world and main forest forming component in Europe. Based on genetic, morphological and growth performance traits, several local ecotypes of the species were distinguished across the species distribution range. The existence of...
