title: Cytogenetic Abnormalities in Seed Progenies of <i>Pinus Pallasiana</i> D. Don Stands from Technogenic Polluted Lands in the Steppe of Ukraine
abstract: Abstract In this study, we compare the pathological mitosis rates, chromosomal abnormalities and nucleolar organizer activity in Pinus pallasiana D. Don seedlings from natural population in the Crimean Mountains and from the urban plantations in the steppe of Ukraine. On the stages of anaphase and telophase of mitosis, such chromosomal abnormalities as bridges were most often found in the seeds of plantations exposed to air pollutants, whereas lead and agglutination of chromosomes were found in
