Genetic Variability of Natural Populations and Man-Made Stands of Common Pine (Pinus sylvestris L.) in Kremenets Hills and Maloe Polese

摘要

Comparative analysis of 19 allozyme loci of Pinus sylvestris L was performed on three relic populations and six uneven-aged man-made stands to evaluate genetic variability of common pine in Kremenets Hills and Maloye Polesye. Low heterozygosity was characteristic of all natural populations and of four forest stands (H_0 = 0.182-0.205), whereas in two forest stands the level of heterozygosity was noticeably higher (H_0 = 0.245-0.300). Both allelic and genotypic variability of natural populations was reproducible in the man-made forest. However, the genetic distance between forest stands and natural populations was considerably higher than that among three natural populations (D_(Nav) = 0.014 and D_(Nav) = 0.003, respectively).
