The article discusses the morphological variability of pollen grains of European, Amur, Siberian and Sukachev larch. Two types of pollen grains are found in the studied populations: large ones, the length of which varies in the range of 50-100 µm, and very large ones, the length of which ranges from 100-200 µm. At the same time, the proportion of large pollen grains varies from 60% (L. sibirica) to 77% (L. decidua). The highest content of very large pollen grains in the preparations was observed in the population of Siberian larch. Studies of the quality of larch pollen grains have revealed three main types of anomalies, such as sterile, small and hypertrophied pollen grains, each of which is characterized by morphological and functional disorders.
