Abstract:
Awareness of the importance of the representatives of the genus Amelanchier Medik. concerning perspectives of
enriching genetic resources, in particular to rare valuable fruiting races and importance of the information relating to pollen
quality for botanical, genetic and breeding purposes prompted the study of morphological and functional pollen grains
features of some alien Amelanchier spp. Methods. The pollen quality was determined by acetocarmine pollen viability test,
morphological characteristics were evaluated visually and by means of measurements. Results. It was clarified that the
studied species have pollen grains different in shape, size and fertility. However, the viability of pollen species A. florida
and A. asiatica is higher, compared to A. utahensis. Conclusions. Species with high pollen viability can be considered as
better adapted, and the adaptability level of A. utahensis require more in-depth study according to other criteria.
