Abstract

Tree vegetation of urban green spaces is an integral and functionally important part of the human environment. The purpose of the research is to determine the potential of the collection fund of woody plants of the Kryvyi Rih Botanical Garden for the development of solutions for phytooptimization of the industrial city of the steppe zone of Ukraine. The object of our research was the taxonomic composition, botanical-geographical analysis, life state and decorativeness of woody plants of the Kryvyi Rih Botanical Garden, which belong to the divisions Magnoliophyta and Pinophyta. Identification of taxa was carried out according to the international classification. Vital state was determined according to the methods of L.S. Savelyeva (1975), V.D. Fedorovskyi (2007), V. T. Yarmishko (2002). Decorativeness of plants was studied according to the scale of Zh.A. Vardanian (2017). The results of the study show that the collection fund of woody plants of the Kryvyi Rih Botanical Garden of the National Academy of Sciences of Ukraine includes 720 species, 31 subspecies, 24 varieties, 421 cultivars, 1 intergeneric hybrid – a total of 1197 taxa belonging to 56 families and 155 genera. The highest level of vital state was determined in 35% of trees and bushes, slightly reduced in 25%, average in 32%, reduced in 8%. Very high decorativeness is characteristic of 55% of taxa, high – 25%, medium – 15%, low – 5%. Promising 650 species and cultivars of woody plants, which passed the introductory exam in the Kryvyi Rih Botanical Garden of the National Academy of Sciences of Ukraine, are recommended for introduction into landscaping of an industrial city in the steppe zone of Ukraine
