CHANGES OF GENETIC STRUCTURE OF PINUS SYLVESTRIS L. POPULATIONS EXPOSED TO INDUSTRIAL POLLUTION

摘要

Isoenzymatic variation of Pinus sylvestris was analysied in populations from a provenance trial (IUFRO 1982) in Kornik and their replication in Lubon. The two groups of populations originated from the same seed pool, but the one in Lubon was exposed to pollutants emitted during the production of nitroge-phosphorus fertilizers, while the Kornik provenance trial were used as a control group. The parameters determining the genetic structure of the studied populations-frequency of alleles and genotypes (average Number of alleles and genotypes per locus), observed heterozygosity (H_0), and geotypic polymorphism index (p_g)-have higher values in the group of trees tolerant to pollution.
