Abstract: The article presents the results of studying the impact of industrial emissions of enterprises of the city of Murmansk on the fertility of pollen of Sorbus gorodkovii Pojark (Gorodkov’s rowan) – an endemic species of East Fennoscandia. A low level of pollen fertility (35 – 52%) was revealed, especially in the vicinity of the local heating plants, operating on fuel oil. In the samples from all sites, a high proportion of sterile pollen grains was noted (48 – 65%). A significant increase of the proportion of sterile pollen of rowan in the vicinity of industrial enterprises of the city of Murmansk indicates the mutagenic effect of their emissions on the male generative system of S. gorodkovii and the process of gamete formation.
