The steps analysis of some tree plants introduction in ex situ conditions (Azerbaijan)

The article analyzes the degree of introduction of phanerophytes, which form the cultural dendroflora of the northeastern part of the Greater Caucasus (Azerbaijan). The research showed that out of 115 species studied, 11 were naturalized (CH1), 71 species had good viability (CH2), 25 species had medium viability (CH3), 8 species had poor viability (CH4), resistant species (CH5 group) were not found. As a result of the research, it was concluded that woody plants that form the cultural dendroflora of the study area had a different degree of introduction in accordance with environmental requirements. The results of the study showed that for the successful introduction of the studied woody plants, planting and sowing must be carried out from different geographically productive individuals with different geno- and phenotypic characteristics in the natural habitat, taking into account the bioecological characteristics of the species and their historical past, i. e. phylogenesis. It is more expedient to collect and mobilize material.
