SOME ASPECTS OF THE HISTORY OF INTRODUCTION OF REPRESENTATIVES OF MAGNOLIACEAE JUSS. FAMILY IN VOLYN AND PODILLIA

Abstract

The article reflects the results of the study of history of introduction and acclimatization of species of Magnoliaceaе Juss. family in Volyn and Podillia. The research has identified the individual centres of introduction and sources of seed and planting material. The taxonomic composition of Magnoliaceae family in 18 dendrological facilities and green plantations in Volyn Podillia is described. These objects are as follows: Kamenetz-Podilsk and Kremenets botanical gardens, Lviv National University botanical gardens, Khorostkiv and Hermakivka, Bylokrinitsa dendrological park, Bilche-Zolote, Rayiv and Rivne parks, arboreta of Shatsky forestry college and Kozova school arboretum, rosary of Taras Shevchenko Kremenets Regional Humanitarian-Pedagogical Institute, Lutsk, Kamenetz-Podilsk, Ternopil, Rivne, and Berezhany. Collections of botanical gardens, arboreta, parks, seed banks are a vital guarantee of the preservation of species of magnolias. They are used to study the relicts, their distribution in ornamental horticulture and for repatriation in nature. In Volyn and Podillia the following species grow: Liriodendron tulipifera L., M. kobus DC., M. x loebneri Kache., M. acuminata L., M. officinalis Rehd.et Wils., M. tripetala L., M. salicifolia (Sieb.et Zucc.) Maxim., M. x soulangiana Soul.- Bod., 'Rosea', 'Lennei Alba', 'Alexandrina', M. sieboldii K. Koch., M. virginiana L., M. hypoleuca (Sieb.et Zucc.), M. stellata (Sieb.et Zucc.) Maxim., M. obovata Thumb., M. x kewensis Pearce, M. wilsonii (Finet et Gagnep.) Rehder, M. ashei Weatherby, M. liliflora Desr. The Red List of Plants (IUCN Red List Categories and Criteria) encouraged scientists and supporters of nature conservation to focus on gaining new knowledge on the strategy to protect these species. The research has determined that the greatest number of species is concentrated in the collections of the Botanical Garden of the Ivan Franko Lviv University, Kremenets Botanical Gardens and Khorostkovsky Dendropark. Our scientific research will be used to establish taxonomic composition and research representatives of Magnoliaceae family in all dendrological objects of Volyn Podillia.
