[Genetic structure of the populations of Pallas pine (Pinus pallasiana D. Don) reforested in extreme conditions].
The paper reports on an intensive reforestation of Pallas pine (Pinus pallasiana D. Don) in post-fire sites in the native Mountainous Crimean populations and around the previously planted seed-producing trees in ore-mining dumps of the Krivoy Rog region. Self-sown progeny growing in the dump is characterized by a better growth and comes to the reproductive development phase earlier compared to that one growing in post-fire forest. Allele variability at 20 allozyme loci is less in self-sown progeny than in the native populations whereas its heterozygosity level is similar. Genetic distance (D(N)) among self-sown progenies in post-fire sites and ore-mining dump is comparable to that of the natural populations.
