Population-and-genetic aspects of Pinus pallasiana D. Don introduction in industrial regions of the Ukrainian steppe zone

Theoretical and practical aspects of the population-andgenetic approach in introduction based on comparative research of allozimous variability of Pinus pallasiana D. Don in native populations of the Crimea and man-made plantations have been considered under industrially polluted conditions of Kriviy Rig basin and the Azov See coast. It has been found that under mass introduction and definition of selection promising plant groups a significant loss of genetic potential of this pine native populations does not occur.
