Formation and current state of the angiosperms collection of the StavropolBotanical Garden

Abstract

The article presents the results of many years of work with trees and shrubs
on the basis of the Stavropol Botanical Garden. The list of species, forms and cultivars of
woody plants that have passed the introduction test within a 60-year period is analyzed and
presented. The life forms of plants from the dendrological collection of the Garden are
represented by trees and shrubs, the amount of lianas is small. The most numerous families in
the collection are: Berberidaceae Juss., Betulaceae S. F. Gray, Caprifoliaceae Juss., Fabaceae
Lindl., Hydrangeaceae Dumort., Oleaceae Hoffmgg. & Link, Ranunculaceae Juss., Rosaceae
Juss., Salicaceae Mirb., Sapindaceae Juss. The following genera are widely represented in the
collection: Berberis L., Clematis L., Cornus L., Crataegus L., Fraxinus L., Lonicera L.,
Malus P. Mill., Philadelphus L., Populus L., Rosa L., Salix L., Sorbus L., Spiraea L., Syringa
L., Quercus L., Viburnum L., Weigela Thunb. The analysis of the collection funds of woody
angiosperms, which grow on the territory of the arboretum and in the scientific collections of
individual generic complexes (1959-2020) was carried out. Currently, the collection of
Angiosperms (Magnoliophyta) plants of open ground is represented by 1387 taxa, which
belong to 64 families, 156 genera, 636 species, 719 varieties and 32 types, 68 species of
which belong to the category of rare and endangered plants of the local flora, flora of Russia
and CIS countries. The research continues on the conservation and study of 18 species of rare
and endangered woody plants. Dendrological collections of angiosperms of woody plants of
the Stavropol Botanical Garden, which serve for research and selective breeding work, are a
source for enriching the local flora with new plants that can successfully grow and develop
under the conditions of introduction.
