| Summary: | Objective – to analyse is of pollen quality of Picea abies (L.) Karst. in plantations that are exposed to various aerotechnogenic pollution in the conditions of a large industrial city of the steppe zone.
Material and methods. The object of the study is pollen 30–40 year old trees P. abies of nine plantings, eight of which were selected nearly the entire length of Kryviy Rih (120 km) with different levels of pollution and one – outside (control).
Results. It has been established that the highest viability (79.9 %), fertility (86.3 %) and a maximum size of pollen grains from plants characterized by non-urban spaces, and the lowest (48.3 and 46.5 % respectively) – in tree plantations at industrial enterprises "ArcelorMittal Kryviy Rih" pollen which had a minimum size. We have identified a wide range of teratomorfic changes of abnormal pollen and abnormal pollen tubes at germination in the laboratory. General pattern was observed: decreasing quality and increasing the number of abnormal pollen in plants P. abies, affected by vehicle exhaust and emissions of the metallurgical enterprises Kryviy Rih.
Conclusion. It’s proposed to use the frequency of abnormalities of the pollen and pollen tubes P. abies to indicate aerotechnogenic pollution in the industrial cities of Ukraine.
