Cytogenetic quantitative polymorphism was studied in the Picea abies (L.) Karst. seedlings. Seeds were collected from trees in two natural populations of Ukrainian Polesie and introduction plantation in Donbass and grown in the laboratory. It was established that interphase nuclei in offsprings of trees from the plantation and the population in areas with high radioactivity level are smaller than in population with low anthropogenic influence. The number of nucleoli and their area, and nucleusnucleolus ratio was the lowest in the tree progeny from the introduction plantation. Environmental conditions (including radioactive pollution) affect the seed progeny of P. abies which is reflected in its cytogenetic characteristics.
