The indicator of foamy and sparkling properties of finished sparkling wines directly depends on the ability of the base wine to foam. This indicator is influenced by various factors: the grape variety, the composition of the wine material, the agrotechnological and technological methods used. The main purpose of the study was to study the influence of varietal characteristics of grapes on the foaming ability of wine materials produced in the Krasnodar region in the 2022 season. All the original samples were processed and fermented under identical conditions. The study of the component composition of the samples was carried out according to standard methods using modern equipment. To determine the ability of foam formation by the initial samples, a \"Foaming analyzer\" was used, developed by Mishin M.V. on the basis of the Department of Technology of Wine-making and Fermentation named after Professor A.A. Merzhanian, which allows an objective assessment of the quality of foam. The foaming ability of three introduced grape varieties was analyzed: Pinot Blanc, Riesling Rhenish and Chardonnay. The result of the study was the establishment of a connection between the foaming ability of wine materials and the grape variety. In the course of the study, it was found that all the samples under study, both in terms of chemical composition and organoleptic evaluation of the aroma, were suitable for creating sparkling wine. However, according to the totality of the composition (esters, higher alcohols and amino acids), wine materials from the Riesling Rhenish variety had the greatest potential for the formation of foaming capacity for the 2022 season in the Temryuk district of the Krasnodar region.","PeriodicalId":403575,"journal":{"name":"Fruit growing and viticulture of South Russia","volume":"61 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138984863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been shown that markers of regional affiliation can be components whose content in wines practically does not change during the production process. The results of a study of the mineral composition of wines produced by the winemaking enterprise OOO “Imenie Sikory” are presented. Using atomic absorption spectroscopy using the Kvant Z spectrometer (NPF OOO “KORTEK”, Russia), 12 metal elements (Co, Mn, Rb, Cr, Cs, Al, Ba, Zn, Sr, Li, Na, Mg) were determined in the course of studies on atomic emission and absorption spectra. A study was also conducted of the mineral composition of soil samples from vineyards where grapes used for wine production grew. Using the methods of correlation and cluster analysis, as well as using the “random forest” algorithm (for wine samples, the initial data were the content of elements and their pairwise ratios), it was revealed that the mineral composition can serve as a marker of the regional affiliation of wine products, since the studied wine samples are within each variety have a stable mineral composition, regardless of the year of harvest (correlations between the year and the content of elements are insignificant), determined by the characteristics of the site where the grapes grow. Quantitative determination of the components of the mineral complex in combination with mathematical processing of the results allows us to establish the origin of the wines with a reasonable degree of probability. The mineral composition of the studied wines is unique and is determined by the soil characteristics of the vineyard areas of the “Semigorye” geographical object.","PeriodicalId":403575,"journal":{"name":"Fruit growing and viticulture of South Russia","volume":"15 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138984720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key to the cost-effective maintenance of an apple orchard is determined by rational technology, proper care of trees, and the correct selection of varieties. It is worth noting that the average yield capacity of apple fruits on the Don in the years before the reforms did not exceed 40-50 kg/ha. The low yield capacity is explained by the lack of an irrigation system in the orchards, the use seed, strong-growing rootstocks as the main, the rare standing of trees (250-300 tree/ha) in the orchard, an unsuccessful choice of varieties. The determination of the most suitable varieties for the selected climatic zone became the purpose of the research. So, in 2012, in the conditions of the Azov zone of the Rostov region, an intensive type orchard was planted on an area of 84 hectares, in which eight apple varieties of different ripening periods were placed.

Michurin FSC». The biological objects of the study were 22 strawberry selected intervarietal forms from 12 crossing combinations. The allelic state of the FaOMT gene was identified using codominant SCAR marker FaOMT-SI/NO. As a result of the studies, the marker fragment of the functional allele FaOMT+ was identified in 86.4 % of forms. A heterozygous combination of alleles of the FaOMT gene (average level of mesifurane accumulation in fruits) was detected in 9.1 % forms. The homozygous state of the functional allele was detected in 77.3% forms. The homozygous state of the non-functional allele FaOMT- (mesifurane is not produced) is characterized by three genotypes (13.6 %).

In confirmation, emphasis is placed on more favorable edaphoclimatic conditions, the possibility of introducing a non-covering and semi-covering grape culture, a higher adaptability of the population to the industry, due to the proximity to the Khasavyurtovsky District, where the population was engaged in viticulture much earlier. It was found that by the mid-1980s 8 specialized farms (wine collective farms) operated in the district, which are part of the production and collective farm association \"Checheningushvino\". The area of vineyards was systematically growing, the wine collective farms achieved high results in terms of gross production of grapes and grape yield capacity. A special place was given to securing vineyards for mobile groups of wine-growers (family contract) and tenants. The culture of grapes in the region occupied a prestigious place among other branches of the agro-industrial complex. It was especially noted that the processes of intensification of production were launched. High-value grape varieties with increased frost resistance were tested, allowing them to switch to a non-covering crop; the bushes were transferred to more advanced pruning, which were distinguished by a greater capacity in terms of load with shoots, etc. After the release of the Anti-Alcohol Decree and subsequent negative processes that led to the collapse of the country (and to military operations in Chechnya), the industry began to curtail.
