Abstract
Objective – to analyse of vitality of Pinus pallasianа D. Don. and P. sylvestris L. plants in iron ore dumps of Kryvyi Rih area and their ability to renewal.
Material and methods. We investigated condition of plantings of Pinus pallasiana (30–35-year-old) and P. sylvestris (20–25-year-old) in three iron ore dumps of Kryvyi Rih area as well in the arboretum of Kryvyi Rih Botanical Garden of the NAS of Ukraine.
Results. We ascertained that individuals from plantings in iron are dumps are inferior to ones from the arboretum of Botanical Garden in their morphometrical characteristics but they stand out with their high vitality level in conditions of dumps where their seed renewal proceeds. Young self-seeding pine plants start reproductive phase of their development early and promote the renewal of both species also.
Conclusion. It is factically process of forming of local isolated populations of Pinus pallasiana and P. sylvestris in drastically technogenically changed territories in steppe zone of Ukraine.
