Abstract: Generalization and analysis of experimental data concerning peculiarities of passing and duration of various phenological phases of Th. plicata, their consistency with the sums of effective temperatures is provided in the article. Conducted researches based on observations and mathematical processing allowed to reveal the regularity of passing of all vegetative and generative phases in the area of introduction and to reveal the dependence of these processes on ecological factors. It was found that the vegetation period of this species is 151 ± 3 days. Influence of nature and degree of temperature, air humidity and rainfall on the growth of shoots were also determined. It turned out that air temperature has the greatest influence on the growth peculiarities of one-year shoots. Growth of shoots begins after changing of the average daily temperature above +9°C. Culmination of increments is observed in May, when the temperature is 13-18°C. Then, increments are fading with the increase in temperature and decrease in humidity and the second wave of growth occurs in August. Shoots completely finish their growth in September. Precipitation and humidity do not have a significant effect on the growth of shoots.
