[Allozyme variation of seed embryos and mating system in relict populations of Scots pine (Pinus sylvestris L.) from the Kremenets Hill Ridge and Maloe Poles'e].

Allozyme variation at ten polymorphic loci and mating system was studied in three small isolated relict populations (4.4 to 22 ha) and in three artificial stands of Pinus sylvestris from the Kremenets Hill Ridge and Maloe Poles'e. It was established that the mean heterozygosity of 130 to 140 year-old trees from natural populations (H(O) = 0.

[Genetic variability of the natural populations and man-made forests of Pinus sylvestris L. from Kremenets Hills and Maloe Poles'e].

Comparative analysis of genetic variability of three relic populations and six forest stands of different age grown in Kremenets Hills and Maloye Polesye has been carried out at 19 allozyme loci. All populations and four forest stands were characterized by a low level of heterozygosity (Ho = 0.245-0.

[Peculiarities of population-genetic structure of Norway spruce (Picea abies (L.) Karst) from Ukrainian Carpathians and Poles'e].

Genetic differences of various populations of Picea abies (L.) Karst.) have been studied basing on 20 allozyme loci variability.
