title: [Polymorphism of superoxiddismutase in chronically irradiated Scots pine populations].
abstract: Polymorphism ofsuperoxidedismutase in Scots pine populations from the Bryansk region radioactively contaminated as a result of the Chernobyl accident was studied. The frequency of mutations in the isozyme loci, the effective number of alleles, intrapopulation diversity, as well as the frequency of rare morphs were significantly increased along with the level of radioactive contamination. Changes in the genetic makeup of the populations under study were due to the increased frequency of rare alleles.
