Genetic polymorphism in Siberian stone pine (Pinus sibirica Du Tour) populations from Ural and Altai-Sayan mountains

open access: yesПроблемы ботаники южной сибири и монголии, 2020
The article presents the results of analysis of the variability of 23 allozyme loci in 10 populations of Siberian Stone pine. Populations from South Siberia mountain regions had higher percentage of polymorphic loci in averageand mean number of alleles per loci (P99% = 44,57 %, NA = 1,543 ± 0,014) compared to Ural populations (P99%=29,57%,NA = 1,348 ...

Genetic variation in Siberian stone pine (Pinus sibirica Du Tour) group and individuals seedlings from the south of Western Siberia forest zone

open access: yesПроблемы ботаники Южной Сибири и Монголии, 2022
In forests with the participation of Siberian stone pine, you can often find group seedlings - young plants grow in groups, closely adjacent to each other. The reason for this is the zoochoric method of spreading Siberian stone pine seeds - group seedlings appear from seeds hidden by nutcracker in the ground cover.

Cyclic Variation of Residual (CO2 + H2O) and Total Pressure in Conifer Stem and Woody Root Tree Rings [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2018
Tree-ring chronologies of stem discs and core samples have been widely used to reconstruct the climatic conditions of tree growth. However, insufficient attention has been given to the fact that root and stem wood accumulate biogenic gases, whose ...

Influence of weather factors on seed cone formation of Siberian stone pine Pinus sibirica Du Tour (Pinaceae Lindl.)

open access: yesПроблемы ботаники Южной Сибири и Монголии, 2023
Nowadays, when studying the fruiting of tree species, it is of great interest to understand the influence of weather factors on the inter-annual variability of fruit and seed yield. Siberian stone pine covers a large part of the Asian part of Russia and is valued primarily for its seeds.
