ВНЕСОК КРЕМЕНЕЦЬКОГО БОТАНІЧНОГО САДУ В РОЗВИТОК БОТАНІЧНОЇ НАУКИ

The article highlights the role of the Kremenets Botanical Garden in the preservation and enrichment of plant biodiversity. It also analyzes the current state and prospects of plant biodiversity development as a scientific center where research is carried out on the plants introduction, reintroduction and acclimatization, landscape design and greening, and the organization of environmental monitoring. The main directions of the institution's scientific work at the current stage are outlined. The structural scientific unit of the institution consists of six departments: acclimatization of fruit and berry crops; dendrology; flower garden and decorative plants; medicinal plants and new crops; reproductive biology and implementation; phytosozology. Main research topics: introduction of plants with the aim of enriching plant resources of Ukraine; preservation of the gene pool and biodiversity of species ex situ, protection of flora and monitoring of its condition, reproduction, cultivation, implementation of introduced and native ornamental plants with the aim of renewing collections and greening. The collection fund of the botanical garden includes more than 2,000 taxa, among them: species protected in national (listed in the Red Books of Ukraine) and regional levels, endemics of the Kremenets Mountains and other regions of the world. The species of natural flora, dendroflora, berry and fruit crops, medical, fodder, vegetable, spicy-aromatic and decorative plants are widely represented in the collections and expositions. A thorough study of the development of these plant groups allows us to determine their individual peculiarities, develop agricultural techniques, select the most promising species and to use the information obtained when creating plant compositions. The study and construction of plant populations of the desinent group is actively conducted in the Kremenets Botanical Garden. Also, the monitoring and control of the spontaneous spreading of invasive species are carried out. The modern Kremenets Botanical Garden is an object of the national nature reserve fund. It participates in the environmental protection activities of the region and functions as a research and educational institution. Multi-faceted scientific research is carried out here, as well as cultural and educational work.
