Influence of innovative forms of fertilizers on the adaptive potential of tea plants

Abstract

The article is dedicated to the search for effective ways to regulate the functional state of tea plants under stress that ensure an increase in yield and its stability in varying climatic conditions, preserving and improving the quality of products (finished tea). The research was carried out during 2019-2020 on the basis of the Adygeya Branch of the Federal Research Centre “The Subtropical Scientific Centre of the Russian Academy of Sciences” on tea plants of the Kimyn variety population. It is shown that the winter period can be considered comfortable for the tea culture, while in the summer the plants regularly suffer hydrothermal stress. During the action of stress factors in the period of summer depression, in the pre-winter months (October-November), on variants with foliar treatments with innovative forms of fertilizers, there was a slight increase in bound water, active formation of proline and ascorbic acid in physiologically mature tea leaves. The use of innovative forms of fertilizers is an element of activation of the nonspecific protection mechanism and can become the main element of the technology of cultivation of tea plants.
