INTRODUCTION OF TREE AND SHRUB PLANTS IN THE BOTANICAL NURSERY OF THE UMAN NATIONAL UNIVERSITY

Abstract

The article reveals the history of the introduction of dendroflora of the forest park zone of the botanical nursery since the time of the Main School of Horticulture (now Uman National University). Collections of introducers are created to ensure the educational process in the fundamental disciplines: botany, introduction and preservation of the plant world, and decorative horticulture. Here, old stands of Pinus nigra subsp. pallasiana (Lamb.) Holmboe., whose age exceeds 170 years. The site borders the arboretum named after V.V. Pashkevych of the Sofiivka National Dendrological Park of the National Academy of Sciences of Ukraine. The taxonomic composition of the trees and shrubs of the collection site, their natural range, which includes 4 families, 9 genera, 11 species from the Gymnosperms department and 24 families, 48 genera, 78 species of Angiosperms is presented. The collection is replenished with new cultivars to this day. Generally accepted methods of floristic research in botany, dendrology proposed by Ukrainian scientists O.L. Lypa, M.M. Grishko, M.A. Kohno, O.O. Kalinichenko, who studied the introduction and adaptation of plants in Ukraine. An assessment of the success of the introduction in the conditions of the Right Bank Forest Steppe of Ukraine, in particular the city of Uman, Cherkasy Region, was carried out. Data on the diagnostic condition of the plantings in the landscaping of the university campus were obtained, which testify to their excellent adaptive properties. The species Acer campestre L., A. platanoides L., A. tataricum L., Carpinus betulus L., Corylus colurna L., Euonymus europaeus L., Juglans cinerea L., J. nigra L., J. regia L., Liriodendron tulipifera L., Magnolia kobus DC., Morus nigra L., Sambucus nigra L. do not require careful care and are promising for introduction in these conditions. Decorative shrub species of the genus Buddleja Houst. ex L., Calycanthus L., Deutzia Thunb., Hydrangea Gronov. ex L., Exochorda Lindl., Forsythia Vahl, Kerria DC., Kolkwitzia Graebn., Prunus L., Pyracantha M.Roem., Rhododendron L., Spiraea L., Syringa L., Weigela Thunb. are mother plants for obtaining cutting material for their reproduction in the conditions of the greenhouse-greenhouse complex of the university. The botanical nursery is an important research base for students of the E1 Biology and Biochemistry specialty. It functions as a center for the study of taxonomic diversity, analysis of ecological and biological features of plants, their reproduction and use in landscape compositions during qualification works. During classes, students acquire theoretical and practical skills in the study of dendroflora, introduction and conservation of plants, use in landscaping, collection of herbarium material, carpological collection to replenish herbarium funds (UM).
