Abstract

The article presents the results of the study of some rare and endangered species, mainly introduced ones, from arboretums of All-Russian Research Institute of Forest Genetics, Breeding and Biotechnology and Voronezh State University of Forestry and Technologies named after G.F. Morozov (both in Voronezh, Russia). It examines their ecological and biological characteristics and phenological patterns. The paper presents phenological spectra with the phases of the seasonal development for the studied species. It also explores the issues of the stability and plasticity of the introduced species and designs methodologies for their conservation and reproduction. Based on many years of observations the paper concludes that the studied species have the potential to be used for forestry and gardening of the Central Chernozem Region of Russia.
