Assessment of the ecological and biological features of the development of shrub introduced species in the conditions of the Central Black Earth Region.
In the course of research, the authors analyzed the results of the introduction of shrub plants of different taxonomic groups in the conditions of the Central Black Earth Region. Most of the representatives of the collections under consideration (a collection of deciduous shrubs, a collection of ornamental shrubs, a collection of coniferous shrubs) showed significant adaptive capabilities in the conditions of the region under consideration. Recommendations on the possibility of using introduced shrubs in green urban construction are given, and species and forms that are not suitable for this purpose are identified. The authors have developed a methodology for assessing the results of introduction tests of shrub plants using the example of the Central Black Earth Region, which can be used in other regions of the Russian Federation and countries of the world to conduct similar tests. This technique is quite simple, but it allows you to create a complete picture of the adaptive capabilities of introduced species, since is based on basic indicators of plant vitality (drought resistance, winter hardiness, average annual growth, observation of flowering and seed production).
