INFLUENCE OF FERTILIZERS ON QUALITY OF CHARDONNAY GRAPES AND WINE MATERIALS

abstract 1471903014 issue 147 pp. 0 – 0 29.03.2019 ru 38
The article presents the results of the fertilizers use effect on dry wine materials produced from the Chardonnay variety, grown in the Anapo-Taman soil and climatic zone of the Krasnodar region, Russia. As a result of wine materials analysis, increase of tartaric acid was noted, with the autumn application of phosphorus-potassium fertilizers and the spring application of ammonium nitrate. At the same time, its optimum content was noted with nitroammophos. Also, the minimum concentration of malic acids was detected by the application of nitroammophos with potassium fertilizers. In its turn, early spring application of ammonium nitrate reduced the concentration of malic acid below the control sample (without fertilizers). It was revealed that the use of mineral fertilizers in this winemaking zone also contributed to a reduction of lactic acid in the must. At the same time, the application of nitroammophos (especially together with other mineral fertilizers), contributed to the accumulation of citric and succinic acids, as well as phenolic compounds. Moreover, the application of phosphate-potassium fertilizers in the autumn contributed to the accumulation, and, consequently, also to the increase in the content of phenolic compounds in the resulting must. In addition, the studied samples of wine materials contained high alcohol concentrations and low concentrations of sugars with volatile acids. At the same time, the maximum amount of alcohol exceeding its content in the control sample was revealed when phosphorus-potassium fertilizers were used together with nitroammophos fertilizers. It is also noted that the application of ammonium nitrate did not affect this indicator. As a result, the use of mineral fertilizers in the studied concentrations made it possible to prepare wine materials that contained a low concentration of sulfur dioxide, which is substantially lower than the harmful concentration for humans. In addition, increased concentrations of hydrogen ions in variants with the application of phosphate-potassium fertilizers have made it possible to reduce the number of iron tanates and the intensity of oxidation-reduction processes

INFLUENCE OF FRUITLESS SHOOTS ON QUANTATIVE TRAITS OF GRAPES AND WINE OF SAPERAVI VARIETY

abstract 1081504038 issue 108 pp. 512 – 532 30.04.2015 ru 941
In this study we have shown the influence of fruitless shoots to number of berries in clusters, the mass of 100 berries, average weight of the bunch, yield, sugar content and acid in the juice of the berries, the quality of wine. These indicators have been studied at a ratio of fertile and sterile shoots 1: 1, 3: 1, 6: 1 with a load of bushes 12, 16, 20 fruit-bearing shoots and nutrition area 3 x 1 m2. Control was a natural balance of fruit-bearing and barren shoots. Digital material is processed by one-way analysis of variance experience for each load of bushes, and then the same method of two-experience for all the options. Fragmentation of sterile shoots with load of 12 fruit-bearing shoots per plant decreases, and with loads of 16 and 20 increases the number of fruit-bearing shoots berries in clusters, the mass of 100 berries, average weight of the bunch, yield, and sugar content in berries. For the content of titratable acids we have marked a tendency to increase with a decrease in the number of sterile shoots. The content of phenolic substances on the variants of the experiment was 2.2-2.3 g / dm3, the acidity of 7.3-7.8 g / dm3, alcohol 10,2-10,9% vol. Dry wines tasting score on the options was in the range of 7.4-7.6 points. Significant difference in taste and smell features wines by variants of the experiment was not revealed. Conclusions on the effect of sterile shoots on fruiting vine indicators drawn from the analysis of variance one- and two-factor experiments, in most cases were the same

INFLUENCE OF THE NEW RACES OF YEASTS ON THE CHEMICAL COMPOSITION OF THE WHITE TABLE FAULTS

abstract 1001406107 issue 100 pp. 1629 – 1639 30.06.2014 ru 905
The influence is shown for the race of yeasts to the dynamics of the fermentation of grape must, the composition of organic acids and aromatic of components. The races, which ensure obtaining high-quality winemakings material are presented

INNOVATIONS OF VITICULTURE IN RUSSIA. 6. THE STATE REGISTRY OF GRAPE VARITIES OF RUSSIA

abstract 0540910011 issue 54 pp. 196 – 204 21.12.2009 ru 4308
The state register of selection achievements admitted to use in manufacture is a long-term collective work of the big number of researchers and the production workers, only partially reflected in the separate printing editions resulted in the list of the literature. For today, there are 170 scion grapes grades in the register, including 76 table, 73 technical and 21 universal directions of use, and also 17 stocks. From number of scion varieties there are 109 domestic and 61 foreign, 35 native and 135 selection grades. The state registry is the basic innovation document of wine-growers used as a manual at creation of ampelocenoseums and manufacture of the most valuable production

INNOVATIONS OF VITICULTURE IN RUSSIA. 3. CLONAL SELECTION OF GRAPES

abstract 0540910008 issue 54 pp. 131 – 159 21.12.2009 ru 2182
Clone selection of usually zoned grades of grapes nowadays is made in all countries of the developed wine growing and this way increases not only productivity level, but also quality of raw materials. Process of clone selection is complicated by long-term finding-out of presence of changes of genotypical grade environment. For simplification of selection of a highly productive protoclone of selected grades use of the advanced methods of genetic marking of pluses-transgressions and selection of nucleotidically changed plants with a complex of high values of valuable quantitative signs is necessary
