“…Agroecological assessment of the natural resources of the region was allowed us to identify the main factors limiting the productivity of tea plants -low air temperatures in the winter and early spring periods, insufficient moisture supply in combination with high temperatures and atmospheric drought in the summer months [3]. This is what causes the low yield of tea plantations in this region of 20±5 c/ha (with 80±10 c/ha in the Krasnodar Territory) [4]. However, the analysis of the quality characteristics of raw materials (tannin on average 29.7±2.4%, extractive substances -37.6±9.7%) shows the undoubted prospects of its production in Adygea in comparison with the biochemical indicators of the tea sprouts in coastal zones (tannin about 26.4±1.9%, extractive substances-29.2±4.2%) [5].…”

The research is aimed at finding effective ways to regulate the functional state of tea plants under stress, increase in yield and its stability, preserving and improving the quality. Foliar spraying of the tea stimulated the active formation of Proline (135.1-179.2 mg/g, in the control - 122.6 mg/g) and ascorbic acid (177.8-226.5 mg/g, in the control - 131.4 mg/g) in the leaves, which indicates the inclusion of processes associated with the mechanism of nonspecific protection against stress. The optimal state of tea plants treated with fertilizers explains the more developed specific surface density of the leaf (1.44 mg/cm2, in the control -1.24 mg/cm). The developed specific surface density of the leaf was ensuring the active operation of the leaf apparatus on the experimental variants, which is expressed in a higher productivity of the leaves (1.27-1.31 g/dm2), compared to the control plants. The highest yield (about 23.05 centner per ha) was observed in the variant with foliar treatments with rokogumin, in the variant with sodium humate (31.47 centner per ha), the yield exceeded the control (26.88 centner per ha) only in 2020, which may be due to the accumulative effect.

The article provides information on one of the research areas of the Adygh branch of the Federal State Budgetary Institution of Science «Federal Research Center «Subtropical Scientific Center of the Russian Academy of Sciences» related to walnut crops. The territorial location of the institution is the foothills of the Republic of Adygea. Scientific research work in the field of nut crops has been carried out in the Adygh branch of the FRC SSC 9f the RAS practically from the moment of its foundation since 1968. Expeditionary studies started in 2008 and were carried out until 2019. As a result of the expeditionary studies, 211 promising forms of Common hazel, 23 promising forms of walnut and 85 promising forms of sowing chestnut were isolated from local populations. The article provides data on experimental collection plots where selected promising forms and known varieties of common hazel, walnut, seed chestnut and common pecan grow. Information is given on the forms and varieties of walnut crops growing in the experimental collection plots. On the basis of the data presented it has been concluded that the Republic of Adygea acts as a donor of reserve territories with suitable climatic conditions for the cultivation of walnut crops; on the basis of the Adygh branch of the FRC of SSC of the RAS the gene pool of common hazel, walnut, common chestnut and common pecan is preserved, studied and replenished. To resolve the issue of using the gene pool of nut crops of the Adygh branch for further breeding work, it is necessary to study the features of their phenology, as well as assess the state of plants during the annual development cycle.
