Aim. Study of DNA polymorphism of 7 coenopopulations of Siberian stone pine (Pinus sibirica) growing in theKuznetsk Alatau. Methods. Nuclear microsatellite loci developed for P. sibirica were used as genetic markers. Results. 44 allelic variants were identified from 11 nuclear microsatellite loci, which significantly differ in the composition and frequency of occurrence of the studied P. sibirica coenopopulations. The highest level of allelic diversity is found in loci Ps_80612 and Ps_1502048, where 8 and 7 alleles were identified, respectively. The calculation of the main parameters of genetic diversity showed a relatively low level of polymorphism in the studied samples (NA = 3.078; NE = 1.877; HE = 0.445; HO = 0.401). The assessment of the degree of genetic differences between populations using the Nei genetic distance (DN) showed that, despite the low genetic differentiation (DN varies from 0.019 to 0.061), the differences between them can be traced quite clearly. Conclusions. Differences in the level of genetic polymorphism of P. sibirica is defined by the presence of orographic and phytocoenotic barriers between coenopopulations, as well as a high degree of ecological and anthropogenic extremity of individual growth sites. Keywords: Pinus sibirica, Kuznetsk Alatau, microsatellites, genetic diversity, heterozygosity.

Abstract The total of 257 trees from the ten natural Siberian stone pine populations of West Siberian Plain, Ural Mountains and Kuznetsk Alatau were studied with the eight nuclear microsatellite loci. Differentiation of population groups indicates the possible existence of separate refugia in the past in the Urals and Kuznetsk Alatau. The northern populations of Western Siberia were characterized by a reduced level of genetic diversity, which could be a consequence of the founder effect in the process of P. sibirica migration from the southern regions of Western Siberia and the Urals since the end of the last glacial maximum. The genetic variability distribution among populations shows the uneven dynamics of Siberian stone pine migration from the zones of supposed refugia. The map of the proposed ways of Siberian stone pine migration from the zones of possible refugia was constructed, and it is in a good agreement with the results of palynological investigations.

Background and aims – Siberian stone pine is a keystone species for Siberia, and numerous studies have analyzed Siberian stone pine seeding dynamics in connection with the dynamics of weather conditions. However, all studies were based on observations before 1990. The aim of the study was to expand our knowledge about the balance of weather and climatic factors in the regulation of cone production to enable conclusions about the current reproductive function in Siberian stone pine.Material and methods – We monitored Siberian stone pine cone production in the southeastern region of the Western Siberian Plain, in association with climatic factors, over a period of 30 years. To analyze the relationship with weather conditions, we used the trait mature cone number per tree and weather data obtained from the weather station in Tomsk.Key results – During this period, cone production decreased by about one-third, mainly caused by the complete absence of high yields. The main factor negatively affecting cone production was late spring frost: severe frost occurring with a large accumulated sum of effective temperatures resulted in full cone loss, and light frost substantially reduced cone number. A less important but significant climatic factor was September temperature: as the temperature increased, the cone number decreased in the following year. Over the last 30 years, the sum of the effective temperatures at which the last spring frost occurs, as well as the average September temperature, increased considerably, resulting in reduced cone production.Conclusion – If the current climatic trend is maintained, and especially if it is strengthened, Siberian stone pine cone production in the southern boreal forest zone on the Western Siberian Plane is unlikely to provide for the effective renewal of the species.

Hybrid Forms

Siberian stone pine (Pinus sibirica) and Siberian dwarf pine (P. pumila) are Russian five-needle pines withdifferent life forms, namely upright tree and prostrate tree, respectively. Hybridization of the species was considered in thepaper from the point of view of the habitus of their natural hybrids. In early studies, it was always noted that the hybridswere intermediate in comparison with the parental species. Crown structure in hybrids are largely determined by twomain factors. These are deflection of the tree stem from the vertical axis and the selectivity of apical dominance. Hybridsgrowing in open places under full lighting conditions are characterized by strictly intermediate growth form. In a forestwhere there is no enough light, hybrid reaches for sun but gradually deviates to the side, which ultimately leads to a branchbreak or even the roots of the entire tree being upturned from the soil. In the mountains, hybrids can form uniform trunkbranches, forming a cup-shaped crown, similar to how it happens in Siberian dwarf pine. Thus, the previously notedintermediate morphology of hybrids represents a series of forms, from almost vertical multi-stemmed trees to pumila-likeones with a cup-shaped crown.
