Various anomalies in flowers structure of 17 plant species have been revealed and described. Some aspects of teratogenesis dynamics in Fragaria vesca L. generative organs have been investigated. Quantitative estimation of heavy metals contents in plant material has been carried out. There have been detected, that the anomalies of apricot, cherry and apple flowers result in significant decrease of seed production of plants.
