This article is aimed at identifying the relationship between the territories agro-ecological conditions and the anthocyanins complex formation of grapes, which determines the quality and biological value of red wines. Using HPLC, the anthocyanins complex of 'Cabernet Sauvignon' cultivar from 6 industrial vineyards, located in three natural regions of Crimea, was studied. The agro-climatic resources of vineyards were assessed using the methods of geoinformation and mathematical modeling. It was detected that according to parameters of heat and moisture supply vineyards discriminated with Wilks L. = 0.007; α<0.00001. The direct correlation (r = 0.88-0.95) was identified between growing degree days above 10 °C, growing degree days above 20 °C, Winkler index, average growing season temperature and the rate of monoglucosides of malvidin and its derivatives in anthocyanins complex of berries; the inverse correlation – between the same agroecological indexes and the rate of cyanidin, petunidin and their derivatives. The similarity (Ed = 2.79-2.98) of anthocyanins complex of grapes from Villino v., Uglovoe v. and Yalta t. located in the western foothill-coastal and south coast regions was discovered. The highest content of anthocyanins was found in grapes from Privetnoe v. (5487 ± 384 mg kg-1), the smallest - from Solnechnaya Dolina v. (2154 ± 129 mg kg-1) located in the same natural region. The results obtained indicate the need for a "point" assessment of the agro-ecological resources for creation of industrial vineyards.

The work is aimed at identifying the relationship between agroecological conditions and the formation of carbohydrate-acid and phenolic grape complexes. The agro-climatic parameters of 14 cv. ‘Cabernet Sauvignon’ industrial vineyards located in five wine-growing regions of Crimea have been determined using the methods of geoinformation and mathematical modeling. According to the similarity of 9 agro-climatic characteristics, the vineyards are united into 6 clusters, significantly different from each other. The dispersion of the main and secondary metabolites of grapes, as well as technological indicators based on them in the harvest from the selected clusters, has been established. According to the combined mass concentration of anthocyanins in berries, potential amount of extractable anthocyanins, anthocyanin extractability, monophenolmonooxygenase activity, glucoacidimetric index and grape ripeness index the selected vineyard clusters are discriminated with Wilks L. = 0.09 at α<0.00001. Sugar content, active acidity index, glucoacidimetric index, and grape ripeness index were found to correlate inversely with the amount of precipitation during the growing season; anthocyanin extractability correlates directly with the Huglin and Winkler indices; monophenolmonooxygenase activity with the sum of active temperatures above 10 °C, Huglin index, total precipitation per year and growing season.

“…The active transformation of vineyards from traditional to organic management systems [57], as well as the involvement of fallow lands in viticulture, increase the value of the soil biological activity assessment as one of the most important indicators of its condition, including the ampelocenoses of the Northern Black Sea region. In this scenario, the soil microbial respiration, the microbial activity and biomass, and the changes in ecophysiological status may indicate unfavorable processes induced by a combination of agrogenic factors.…”

The present study investigates the functionalecological status of typical light clay soils in vineyards in the southern region of Crimea, using both traditional (including fallow soils) and organic land-use systems. This analysis was carried out by examining agrochemical indicators, microbial respiratory activity, microbial biomass, and the ecological status of the microbial community. In organic vineyard soils, the mean substrate-induced respiration, microbial biomass carbon and the ratio of microbial biomass to organic carbon were found to be 2.8, 4.0, and 4.1 times higher, respectively, compared to conventional farm soils. On the contrary, the microbial metabolic coefficient was 1.4 times lower, signifying more favorable conditions for the functioning of the soil microbiota. The increased mobile sulfur content in organic vineyard soils (18.3 mg kg−1 vs. 8.0 mg kg−1 in traditional farms) and inadequate mobile phosphorus supply in some farms present potential risks. The suboptimal functional state of the microbiome in fallow soils previously under traditional plant protection necessitates comprehensive ecotoxicological analyses before development. Assessing the soil functional ecological status through an ecophysiological evaluation of the microbiome is vital for understanding ampelocenosis soils and making informed decisions on vineyard management practices.
