As a result of the study of photosynthesis, transpiration and respiration of the leaves, functional features of these processes were revealed during the vegetation period in the late pear varieties Noyabriskaya and Vystavochnaya and Socrovishce of different ages and under different growth conditions. Synchronism of these life-determining growth processes is revealed, revealing the coordination level of the organization of physiological processes, which provides a single rhythm of seasonal dynamics of development and plant productivity. Studies have shown a close relationship between the realization of the photosynthetic function and epigenetic development processes, the change in the donor and acceptor functions of the leaf. Knowledge of the features of these processes in different species and varieties of fruit plants is necessary for choosing ways to optimize their photosynthetic activity. The study of the effect of the biologically active compound verbaskozid on the photosynthetic activity of young and fruit-bearing pear plants showed that one of such ways is the application of treatment with this preparation as an important and promising in increasing the productivity and yield of pear plants.
