It was studied that the dynamics of phenophases, the dates of the beginning and duration of phenological cycles in plants are under the constant influence of seasonal changes in climatic conditions (regular alternation of seasons with different durations of day and night, warm or cold and rainy or dry seasons). Together with the study of the shoot growth duration, it is worth conducting a study of the dynamics of their growth. This is also important for determining the tolerance for winter conditions, since it is known, that not only those shoots that finish growing early but also those that grow for a long time, but rather slowly, can be winter resistant.
The intensive growth of shoots of all studied species occurs in May to mid-June. Almost all of them have two peaks of shoot growth: June and mid-July. The growth of shoots has a certain dependence on air temperature.
The conducted long-term phenological observations made it possible to establish the periods of phenophases in five species of shrubs and show that in the conditions of the Right-Bank Forest-Steppe, all of them manage to complete their vegetation in time, before the beginning of frost.
Among the studied species, <italic>Lonicera tatarica</italic> L. and <italic>Viburnum lantana</italic> L. were the first to start their shoot growth in the first decade of May. Then, in the third decade of May, shoots of <italic>E. europaeus</italic> began to grow. <italic>P. spinosa</italic> and <italic>R. canina</italic> were the last to start their shoot growth.
The conducted research has a certain significance for forest reclamation work as these types of shrubs are used to create protective plantings. Establishing a certain dependence on air temperature will allow to adjust the species composition and their number when creating this type of plantation.
