In botanical gardens, as points of primary intentional introduction, it is necessary to carefully study the tendency for naturalization of cultivated plants, and to conduct a preliminary assessment of their degree of invasiveness. The study analyzed chorological, biological and ecological peculiarities of introduced species of the medicinal plant collection of the Botanical Garden of the Ural Branch of the Russian Academy of Sciences (Yekaterinburg), both absent in natural communities in the territory of the Middle Urals and adventitious. The species in this collection showed relatively low ability to naturalize. Statistically significant relationship with the ability of species to naturalize has been established during cultivation in the subzone of the southern taiga. Such characteristics are: belonging to certain latitudinal (zonal) and longitudinal groups; the relationship of species to temperature and humidity; life form; taxonomic affiliation. Under the conditions of introduction, the impact on the ability to naturalize turned out to be statistically significant for such factors as timing of the beginning of spring regrowth, degree of winter hardiness of plants (assessed by the size of winter loss), the intensity of their seed and vegetative reproduction. The analysis carried out may be useful for forecasting and managing risks associated with the processes of naturalization and invasion of species into natural communities.
