“…One of the directions is the use of phytohormones, which are physiologically active substances. According to several authors [1][2][3][4][5][6][7][8][9][10][11], they can be used to increase the productive sets' formation, which is especially important in adverse weather conditions during periods of generative buds' differentiation and flowering.…”

“…This is the reason for the low yield of 20 ± 5 cwt/ha in the zone [12][13][14]. At the same time, as shown by the studies of domestic and foreign scientists, increasing plant immunity, frost resistance, and drought resistance of crops is possible through the use of plant growth regulators, which are physiologically active substances [1,5,6,10]. Since tea refers to food products, particularly beverages widely consumed by different age groups of the population, it is important to use eco-friendly technologies for cultivating tea plantations on plantations; those include the use of growth regulators used in organic farming.…”

Agroecological assessment of the natural resources of the Adygea allowed to identify the main factors limiting the productivity of tea plants. Such factors determine a low yield and tea quality within the zone. Tea refers as a food product; therefore, to activate productivity and improve quality indicators on plantations, it is possible to use eco-friendly cultivation technologies only, for example, processing with growth regulators, which are used in organic farming. The content of ascorbic acid, extractives and tannin in 3-leaf tea flushes was determined. The treatments with growth regulators activate the accumulation of ascorbic acid by 1.5 - 1.8 times compared to the control option (116.8 mg/g of raw mass). Moreover, the largest amount of ascorbate is synthesized in flushes treated with rokohumin (177.8 mg/g) and bombardier (207.9 mg/g). Studies have shown that when treated with growth regulators, there is a slight increase in the amount of extractives (32.1-34.9 %, in the control – 31.3 %) and tannins (21.7 % – 22.9 %, 20.4 % in the control). The calculation of the smallest significant difference showed the presence of significant differences between the experimental options and the control for all the analysed characteristics.
