Structure of the hybrid zone between Siberian stone pine and Siberian dwarf pine
Проблемы ботаники южной сибири и монголии, 2020 Siberian stone pine (Pinus sibirica) and Siberian dwarf pine (P. pumila) are widespread in northern Asiafive-needle pines from subgenus Strobus. The natural hybridization occurs in many regions where the species growtogether. Traditional hybrid zone model was considered in the paper and, based on the accumulated data, it is determinedwhich one ...

Проблемы ботаники Южной Сибири и Монголии, 2022 For the first time, a comparative analysis of crown morphogenesis in Siberian stone pine (Pinus sibirica), Siberian dwarf pine (P. pumila), their hybrids and backcrosses was carried out using the example of 10-year-old seed offspring from the Northern Baikal natural population. The goal is to “decompose” the life form phenomenon into elementary traits,

Ecological and morphological studies in the hybrid zone between Pinus sibirica and Pinus pumila [PDF]
Annals of Forest Research, 2008 In the Baikal Region, there is no phenological isolation between Siberian stone pine (P. sibirica Du Tour) and Siberian dwarf stone pine (P. pumila (Pall.)Regel) since the timing of their 'flowering' coincides.

Diversity in the morphology of clones of witches’ broom in Siberian stone pine
Проблемы ботаники Южной Сибири и Монголии, 2023 Mutational witches’ broom (WB) is a fragment of a tree crown with abnormally dense branching and slow shoot growth compared with those of a normal crown. All WBs have thicker and denser crown compared to the normal crown part of their parental tree, but the crown density differs significantly among WBs.
