Abstract
Polymorphism of young (14–16 years), middle-aged (70–80 years) and old (120–150 years) plants and their seed embryos have been studied using 10 and 20 allozyme loci from a population of Pinus Pallasiana D. Don from Mountain Crimea. It was determined that the old-aged trees had significantly lower level of expected heterozygosity of embryos in comparison with young trees. Supernumerary homozygotation of the embryos was caused by low level of cross-pollination in three studied samples of plants (t m = 0.537–0.637).
