Abstract
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.
