Genetic polymorphism for GOT and GDH loci of scotch pine seed embryos in the area of nitrogen emissions from the chemical enterprise

Variability for the loci GOT and GDH of seed embryos of three subpopulations of Pinus sylvestris L. exposed to the emissions from the chemical enterprise manufacturing nitrogen fertilizers was studied during four years. The trend to heterozygosity reduction and increased occurrence of the cases of significant deviation of the distribution of genotypes from the theoretically expected one was shown.
