Пыльца представляет собой критический этап в жизненном цикле растений, поскольку жизнеспособность пыльцы имеет решающее значение для эффективного полового размножения растений. Качество пыльцы оценивается на основе ее жизнеспособности. В данном исследовании была изучена пыльца кедрового стланика (Pinus pumila) собранная с кустарников, произрастающих в условиях Крайнего Севера. Для проведения селекционных работ по получению новых перспективных сортов часто возникает необходимость сохранения жизнеспособной пыльцы. Для этих целей было проведено исследование по установлению наиболее оптимальных сроков хранения жизнеспособной пыльцы для дальнейшего использования. Было установлено, что пыльца кедрового стланика может сохранять свою жизнеспособность в течение длительного времени с незначительной потерей способности к прорастанию. Также были выявлены аномалии развития пыльцевых  зерен что указывает на экологическую обстановку мест где произрастает объект исследования. </p></abstract><trans-abstract xml:lang="en"><p>The viability and fertility of pollen play a key role in the development of the plant organism. Pollen represents a critical stage in the plant life cycle, as the viability of pollen is crucial for the effective sexual reproduction of plants. Pollen quality is assessed based on its viability. In this study, the pollen of Siberian dwarf pine (Pinus pumila) collected from shrubs growing in the Far North was studied. In order to carry out breeding work to obtain new promising varieties, it is often necessary to preserve viable pollen. For these purposes, a study was conducted to determine the most optimal shelf life of viable pollen for further use. It has been found that Siberian dwarf pine pollen can maintain its viability for a long time with a slight loss of germination ability. Anomalies in the development of pollen grains were also revealed, which indicates the ecological situation of the places where the object of research grows.  </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Pinus pumila</kwd><kwd>кедровый стланик</kwd><kwd>пыльца</kwd><kwd>хранение пыльцы</kwd><kwd>жизнеспособность</kwd><kwd>фертильность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Pinus pumila</kwd><kwd>Siberian dwarf pine</kwd><kwd>pollen</kwd><kwd>pollen storage</kwd><kwd>viability</kwd><kwd>fertility</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Бажина Е.
