Abstract
Objective — to analyze the quantitative and qualitative composition the taxonomic structure of flower-ornamental plants of Kremenets Botanical Garden.
Material and methods. Nomenclature of species composition is given in accordance with “The Plant List” with refinements for the “Catalog of Life”. Biomorphological analysis of the adventitious fraction was carried out in accordance with the classification of K. Raunkiaer and the system of life forms of I.G. Serebryakov.
Results. It was established that decorative floral cultures of open soil are represented by 3 classes, 46 orders, 65 families, 159 genera, 355 species. The Magnoliopsida class is dominated by the number of species, it is represented by 235 (66 %) species of 114 (71.7 %) genera of 40 (61.5%) families of 34 (74.0 %) orders, Liliopsida class — 92 (26.0 %) species of 30 (18.9 %) genera of 17 (26.1 %) families 11 (24.0 %) orders, Polypodiopsida class — 28 (8.0 %) species of 15 (4.2 %) genera of 8 (2.2 %) families of 1 (1.0 %) order. By the number of species and intrinsic taxa in the collection of herbaceous plants the families Asteraceae, Hostaceae and Crassulaceae prevail.
Conclusions. According to the classification of I.G. Serebryakov in the collection of flowering-ornamental plants polycarpus prevails – 87.0 %, in classification K. Raunkiaer – hemicryptophytes (55.0 %), by hygromorph – mesophytes (46.0 %), by heliomorph – heliophytes (56.9 %), by trophomorph – mesotrophy (60.0 %).
