Dendroflora of the BNAU botanical garden and the prospects for its enrichment in connection with the development of the territory as an object of the nature reserve fund

Abstract

It is shown that the existing dendroflora of the botanical garden of the BSNA is the basis for providing practical training for students of specialties 206 – Horticulture and 205 – Forestry, as well as for conducting scientific research on issues of dendrology, the introduction of ornamental plants, and the development of practical recommendations for the creation of horticulture objects in the conditions of the forest-steppe of Ukraine. The history of the creation of botanical gardens of Ukraine at educational institutions, their role in the development of botanical science, and cognitive value for the training of specialists in natural sciences, as well as their modern aesthetic, educational and environmental role are analyzed. The history of the formation of the biostationary (Botanical Garden) of the BNAU and the formation of its collections is high-lighted. The taxonomic composition, life forms, origin and decorative qualities of woody plants growing in the BNAU Botanical Garden are analyzed. It has been established that currently the dendrocollection of the BNAU Botanical Garden contains 1471 trees, shrubs and vines, which belong to 211 taxa belonging to two divisions of the Pinophyta and Magnoliophyta, 8 subclasses, 27 orders, 35 families, 68 genera. The gymnosperms are represented by one class, 3 orders, 3 families, 10 genera, 23 species and 16 cultivars. From the Pinophyta, the largest number of species (13) and cultivars (19) is united by the family Cupresaceae F. Neger, followed by the family Pianaceae with 13 species and 6 cultivars. From the Magnoliophyta division, the largest number of taxa is represented by the Rosaceae family – 15 genera, 31 species, 2 ornamental forms and 16 cultivars. The second place in terms of representation of genera is occupied by the family Fabaceae Lindl., which is represented in the botanical garden by species from 5 genera. The prospects for enriching the collections of woody plants are revealed, taking into account the reorganization of the biostationary into the BNAU Botanical Garden and the development of its territory as a nature reserve, including further expansion of the collections of woody plants of the Pinophyta and Magnoliophyta departments by representatives of families that are currently absent in the collection, as well as highly decorative species and cultivars that are promising in modern landscaping. The basic principle of organization of the existing and new territory of the Botanical Garden is the formation of collections on a systematic basis, which will allow to use the existing plantings as a basis and supplement them with new taxa. Key words: botanical garden, species, tree, life form, viability, collection, shrub, cultivar, taxon.
