Interpopulation genetic-ecological variation of Scots pine (Pinus sylvestris L.) in Serbia

The genetic-ecological variation of Scots pine (Pinus sylvestris L.) in Serbia was studied in the populations at five localities in western and south-western Serbia. Three groups of Scots pine (Pinus sylvestris L.) populations were differentiated based on genetic research (seed protein analysis) and plant community research. The first group consists of Scots pine populations on Sargan (FMU ?Sargan?) and on Tara (FMU ?Kaluderske Bare?), where the forests belong to the community of Scots pine and Austrian pine (Pinetum sylvestris-nigrae Pavlovic 1951). The second group covers the localities Stolovi (FMU ?Radocelo-Crepuljnik?) and Zlatar (FMU ?Zlatar I?), where the forests belong to the community of Scots pine and spruce (Piceo abietis-Pinetum sylvestris Stefanovic 1960). The third group comprises the Scots pine population on Pester (FMU ?Dubocica-Bare?) which belongs to the community of Scots pine with erica (Erico-Pinetum sylvestris Stefanovic 1963). Cluster analysis was performed on the basis of seed protein data and showed that there are three groups of Scots pine populations. The three populations coincide with plant communities. The community of Scots pine with erica (Erico-Pinetum sylvestris Stefanovic 1963) recorded on Pester at the locality ?Dubocica- Bare? in the area of FE ?Golija? Ivanjica, is a special Scots pine population displayed at the greatest distance from all other populations in the cluster analysis dendrogram.
