Pinus sibirica Du Tour RESPONSE TO CLIMATE CHANGE IN THE FORESTS OF THE KUZNETSK ALATAU MOUNTAINS

open access: yesСибирский лесной журнал, 2019
Climate change has a direct impact on the forest ecosystems of the boreal zone. Temperature increase has a stimulating effect on the advancement of a tree line along the elevation gradient, increase of tree radial increment and stand density. The object of the study was the stands formed by the Siberian pine growing in the forest-tundra ecotone of ...

Allozyme evidence for polyzygotic polyembryony in Siberian stone pine (Pinus sibirica Du Tour)

open access: yesTheoretical and Applied Genetics, 1995
Approximately 4000 mature seeds from 350 trees in nine populations (12-75 trees per population) of Siberian stone pine were investigated for multiple embryos (polyembryony). Haploid megagametophytes and embryos were genotyped for eight allozyme loci. Eight-yone seeds (2.11%) had more than 1 embryo.
