The multi-vector positioning of the Oles Honchar Dnipro National University Botanical Garden (Dnipro, Ukraine) as an ecological resource, the main functions of which are aimed at preserving, studying, acclimatizing plants, researching the effective use of rare and typical species of local and world flora by creating, replenishing and preserving botanical collections, conducting scientific, educational and tutorial work is reviewed. The resource potential study of the fruit and ornamental plants which are promising for various fields of application is a component of bioeconomy. Such plants include species of the order Lamiales Bromhead. In the Oles Honchar Dnipro National University Botanical Garden (Dnipro, Ukraine) the stock collection of Lamiales order plants on condition of sheltered ground was studied. The paradigm of the modern botanical garden positioned as an ecological resource combining research activities, environmental function, and providing society with cultural ecosystem services is highlighted. An inventory and clarification of the taxonomic composition of Lamiales order representatives was carried out for the stock plant collection. The taxa systematic position was determined according to the Angiosperm Phylogeny Group (APG IV) classification. It was determined the geographical status of the species (origin) and its life forms. The data of species' endurance of the Lamiales order to low temperatures in the sheltered ground of the Botanical Garden is given. It is shown that the Botanical Garden has a collection of more than 3,500 species of plants, including 900 taxa in the greenhouse fund, and 63 species, 230 species and cultivars belonging to the order Lamiales. It is demonstrated that Lamiales fruit and ornamental crops, which are available in the collection of the stock greenhouse, have antioxidant properties, and extracts from their parts are characterized by antifungal, antibacterial, and antimutagenic effects. Three collection species of the family Gesneriaceae (Streptocarpus ionanthus subsp. velutinus (B. L. Burtt) Christenh., Streptocarpus intermedia (B. L. Burtt) comb. ined., and Kohleria amabilis (Planch. & Linden) Fritsch) belong to the International Union for Conservation of Nature’s Red List of Threatened Species. Most members of this order can be considered well-adapted to greenhouse growing conditions (88.9 % of plants in the Lamiales collection bloom). Seven species of the family Acanthaceae are fully adapted and give viable self-seeding. Determining the resource potential of the order Lamiales in the sheltered ground of the National University Botanical Garden showed the presence of plants not only with high decorative qualities, but also species containing an increased amount of biologically active substances with a wide range of antioxidant properties.

Now conservation of biodiversity is a relevat topic aimed at increasing phytodiversity in both open and closed ground conditions on the basis of botanical gardens The study of the botanical gardens collections is associated with the investigation of new plants that can be used as a new source of antioxidants and objects of hobby and relaxation for the ever-intense nervous system of modern people.  Family Gesneriaceae Dumort. is an inexhaustible source of such objects. The study purpose is comparison of the family representatives that are similar in terms of morphological features and ecological needs, and differ in geographical origin, analyzing their adaptive capabilities and identifying the most resistant species and varieties. Observations of representatives of Gesneriaceae were carried out from 2019 to 2022 on the basis of the collection of the stock greenhouse of the Laboratory of Tropical and Subtropical Plants of the Botanical Garden of DNU (48°26'7" N, 35°2'34" E, Dnipro, Ukraine). The research objects were 2 species and 22 varieties of Streptocarpus Lindl., 4 species and 2 varieties of Primulina Hance. The qualitative state and development phases were observed in protected soil conditions. Life forms are listed according to the Catalog of Plants of the Botanical Garden of the National University of Ukraine [12]. The systematic position was determined according to the APG IV classification [13]. The taxonomy and names of plant species are given according to the Catalog of life checklist [12]. According to new taxonomy, the genus Saintpaulia H. Wendl. now joined the genus Streptocarpus Lindl. As a result of the research, it was revealed that among the most decorative representatives of the Gesneriaceae family in the collection of the botanical garden of the DNU, grassy perennials with a short stem or rosette occupy a significant place. Namely, species and varieties from the genus Streptocarpus and the genus Primulina Hance. Plants have similar life forms and ecological needs, occupy the same ecological niches in Africa and Madagascar (Streptocarpus ) and Southeast Asia (Primulina). The greatest resistance to modern conditions of keeping plants of protected soil while maintaining maximum decorativeness is demonstrated by species and varieties from the genus Primulina – representatives of the flora of Southeast Asia. Thus, the adaptive capabilities of 4 species and 2 varieties of Primulina turned out to be better than those of other representatives of the Gesneriaceae collection in general and in particular among rosette and short-stem species.
