- Аннотация: Background: Lapland pine (Pinus sylvestris ssp. lapponica Fr. ex Hartm) is the geographical andclimatic ecotype and subspecies of Scots pine. It is widespread in the north of Eurasia. Heightgrowth is interconnected with both climatic parameters and the state of the habitat of pine trees.Methods: Long-term data on height growth indices of Lapland pine (var. nana Pallas (1784)),growing in various humid biogeocenoses of three specially protected natural territories of the NorthEuropean part of Russia were studied. Also sixteen basic climatic parameters averaged over thegrowth period of the examined trees were calculated for these regions. The comparison of thevalues of both different climatic parameters and the height growth of pine stands of variousbiogeocenoses was made by the method of cluster analysis.Results: It was established that climatic parameters such as the mean daily average temperature inJanuary and the amount of precipitation in the spring and early summer periods had a primaryinfluence on the cluster similarity of the height growth of Lapland pine in the North EuropeanRussia. The proximity of soil and biocenotic conditions also influenced the similarity of heightgrowth indices of Lapland pine, but had a lower rank within the two main clusters, distinguished byclimatic values.Conclusion: Our studies showed that it is possible to identify the rank influence of the mostsignificant climatic factors and soil-biocenotic conditions on the height growth of the geographicalecotype Lapland pine subspecies with the cluster analysis.Keywords: Lapland pine, height growth, climatic factors, biocenoses, soil, cluster analysis, Russia.
