The comparative analysis of genetic variation at 12 polymorphic isozyme loci, as well as the mating system, has been carried out in mature trees and their seed progenies in three small localities of Pinus brutia var. stankewiczii Sukacz. in the region between the town of Sudak and settlement of Novyi Svet in Crimea. We found that embryos maintain the same(More)
The quality of pollen and cytogenetic changes of Scotch pine (Pinus sylvestris L.) are studied. The pines growing on different sites in Krivoy Rog (on an iron ore stock dump near a large metallurgical plant and in the tree nursery of the Krivoy Rog Botanical Garden) are compared to plants from the forest district in environmentally unpolluted Ternopol(More)
The genetic structure, subdivision, and differentiation of six populations of tall junipers (Juniperus excelsa Bieb.) in the Crimean Mountains and one population in Lebanon were investigated using 18 polymorphic allozyme loci as genetic markers. A high level of genetic variability of J. excelsa was established at the northern and southern boundaries of(More)
Comparative studies of the frequency and spectrum of pathological mitoses (PMs), as well as of the nucleolus number in the interphase nucleus, in cells of Norway spruce (Picea abies (L.) Karst.) seedlings were carried out in two natural populations of Ukrainian Polesie and plants from an introduction plantation in Donbass. Low levels of PMs in the seed(More)
