The study of pollen viability in trees and shrubs under conditions of introduction is one of the determining factors in the adaptation of a plant to new conditions. In 2018-2019, the vitality and germination of pollen was studied in 9 species of&nbsp;<em>Berberis</em>&nbsp;L.&nbsp;in the collection area of the Institute of Dendrology. For this purpose, the phenology of these species was studied and appropriate methods were applied.&nbsp;The results of the study showed that according to the viability, the pollen of the studied species is divided into 3 groups: highly viable pollen, moderately viable pollen, poorly viable pollen. Meridional and equatorial diameter of pollen of&nbsp;<em>Berberis&nbsp;</em><em>vulgaris</em>&nbsp;and&nbsp;<em>Berberis densifolia</em>&nbsp;species from natural flora, as well as the dimensions of the pollen tubes was large compared to the introduced species.
