Accumulation of biological active substances in Camellia sinensis (L.) Kuntze under the influence of innovative forms of fertilizers
The objects of research are tea plants of the Kimyn cultivar population, growing on the base of the Adyghe branch of the Subtropical Scientific Centre.
The following agrochemicals were used (calculated ha‑1): rokogumin (5 L 150 L‑1 water); sodium humate (150 g 1000 L‑1 water); bombardier (5 L 1000 L‑1 water); consumption of working solutions 50 L ha‑1. Foliar spraying was carried out three times: at the beginning of the growing season after pruning of tea plants (the second decade of May); after the second wave of growth (the first decade of July); in the second decade of November in preparation for the winter dormancy period.
It is shown that the variants with foliar spraying activate the synthesis of assimilant, and more active formation of proline (about 135.1-179.2 mg g‑1, at the control 122.6 mg g‑1) and ascorbic acid (from 177.8 to 226.5 mg g‑1, at the control 131.4 mg g‑1) in tea leaves.
The optimal functional state of plants was accompanied by an increase in the yield of tea leaves (26.3-32.2 centners ha‑1 compared to the control 24.5 centners ha‑1). Significant differences in plant productivity were noted in the variants with rocogumin and sodium humate spraying (LSD (p≤0.05)=2.4) in comparison to the control.
