Shevchenko T. Ecological features of introduction of medicinal plants in agrophytocenoses

In this dissertation, the introduction is studied as a process of conservation of the gene fund and biodiversity and introduction of species into agriculture. Additionally was assessed the ability to naturalize cultivated medicinal plants – introduced species and prevent their negative effects on agrophytocenosis. The ecological features were determined of the analyzed introduced medicinal flora of medicinal products for winter and drought tolerance, on the urge to soil moisture and illumination were determined. The influence of collecting on the study of medicinal plants was assessed. The most promising samples for creation of industrial plantations and representative collection of the thyroid gene pool, which includes 25 samples, was formed and studied according to economic features. In the course of research from 16 samples, three groups of medicinal plants of rare species have been identified for introductory resistance. The nursery of rare species of medicinal plants was formed for reproduction and repatriation. The optimal conditions for the formation of artificial populations have been determined and the recommendations for the creation of such populations for 5 rare species. Ectopic prevalence of 386 introduced medicinal plants was detected: most commonly introduced species of medicinal plants in ruderal ecotopes the number of naturalized species in these ecotopes was 194 species (40%); the smallest amount was detected in segetal ecotope species ‒ 56 species, (12%). A group of 11 invasive dangerous introduced species was allocated, measures were taken to control their spread and a system was developed for assessing the environmental safety of introduced medicinal plants during cultivation.
