In article some results of the introduction of eastasian species of plants in the nursery of Gornotayezhnaya Station FEB RAS are presented. The characteristic of growth rates and winter hardiness of introduced species at early stages of development is given. It is established that seedlings of eastasian plants winter well only in the presence of sufficient snow cover, so young plants need additional shelter. The growth rate of young plants was evaluated on a scale developed by the Department of dendrology of the Main Botanical garden of RAS (GBS). The average height of three-year-old plants is taken as the main indicator of growth rates, and the average annual growth serves as an additional characteristic for unstable species. Biological features of species and the difference in the growth rate are manifested in the first vegetation season. In the conditions of introduction nursery the best characteristics of growth processes have: Kolkwitzia amabilis, Spiraea microgyna, Sambucus sieboldiana; slow growth stand out: Acer trifidum, Acer palmatum, Cotoneaster moupinensis. Most of the studied eastasian species are characterized by an average growth rate at the initial stage of ontogenesis, which contributes to the gradual adaptation of plants to new growing conditions. In many introduction points of the moderate climate zone, eastasian species also have an average growth rate. Thus, it can be concluded that in the conditions of the South of Primorye, introduced eastasian species develop according to their biological features.
