INFLUENCE OF FERTILIZERS ON QUALITY OF CHARDONNAY GRAPES AND WINE MATERIALS

abstract 1471903014 issue 147 pp. 53 – 61 29.03.2019 ru 62
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

PECULIARITIES OF AGROBIOLOGICAL AND TECHNOLOGICAL CHARACTERISTICS OF TECHNICAL WHITE MUSCAT GRAPES OF THE REPUBLIC OF MOLDOVA

abstract 1341710110 issue 134 pp. 1412 – 1436 29.12.2017 ru 68
The results of comparative analysis of three white muscat grades of grapes Viorika, the Muscat de Yaloven and the Muscat onitskan according to the biological indicators of fructification, productivity, quality of berries, mechanical structure of bunches, suitability for manufacture of direct extraction juice and dry wines are depicted in the article. All studied grades differ by high percent of fruiting runaways and high factors of fruiting and fructification. The highest factors of fruiting and fructification of runaways are reflected at grade Viorika, and the lowest - at a grade the Muscat de Yaloven. Biological indicators of fructification of runaways according to the length of a fruit spear are high and rather levelled at all grades. That is why, depending on bushes forming, it is possible to apply short and average (6-7 buds) length of vine cutting. Biological indicators of fructification of runaways from angular buds and sleeping buds are high enough, that shows to good regenerative ability of studied grades. Grades Viorika and the Muscat de Yaloven are tall, and the Muscat onitskan is average height. Degree of ripening of runaways at grades Viorika and the Muscat onitskan is good, at a grade the Muscat de Yaloven - satisfactory. Productivity of grades Viorika, Muscat de Yaloven and the Muscat onitskan is 77,94; 81,52 and 72,72 centner/hectares, and efficiency of runaway - 199,5; 193 and 221,9 with a significant difference between grades on both indicators. The exit of a mash at grades was 77,5-79,4 %. According to the contents of solids, sugars and acids, grapes of all grades correspond to requirements for manufacture of high-quality direct extraction juice. From grapes of these grades, it is possible to produce high-quality direct extraction juice under the name of ampelographic and blended grades. Sampling estimation of dry wines from grapes of these grades fluctuates from 7,6 to 7,8 points: 7,8 (Viorika), 7,7 (the Muscat onitskan), 7,6 (the Muscat de Yaloven)

abstract 1301706090 issue 130 pp. 1236 – 1248 30.06.2017 ru 153
The article reviews the results of studying the influence of mineral fertilizers on the qualitative indices of the Merlot grape variety in the Anapo-Taman zone of the Krasnodar region. The technology of cultivation of grapes on the experimental plot was in accordance with the accepted for the given zone and culture. Agrobiological work was carried out at the optimal time and had a high quality of execution. Grape bushes are laid in a 3.0 x 2.0 m pattern. Formation - a twoshoulder horizontal cordon. On the bushes we formed the same load of shoots and bunches. Scheme of the experiment: option 1 – no fertilizers (control); option 2-superphosphate with a mixture of potassium salt (P90K90) from the autumn; option 3 –nitroammofoska (N120P120K120) from autumn; option 4 – ammonium nitrate (N60) in early spring. Analysis of the results of studies on the study of biological features of growth, fruiting, yield and quality of Merlot grape varieties on the background of the use of mineral fertilizers shows their high efficiency in the conditions of the AnapoTamanskaya zone of the Krasnodar region and can be recommended for use in production conditions. Mineral fertilizers ensures the receipt of dry bulk wine of superior quality control sample (without fertilizers) the concentration of tartaric acid 17.3 25.1 percent, phenolic compounds 17.1 – 40.0 %, and alcohol content of 7.2 and 9.3 %, titratable acids 11.8 and 13.7 %, given extract by 17.4 %, with a decrease of the mass concentration of total sulfur dioxide and pH. The most effective is the introduction of NPK (N120P120K120)

YIELD PREDICTION OF TECHNICAL GRADES OF GRAPES WITH THE WHITE COLOR OF BERRIES ON THE BASIS OF A STUDY OF THE EMBRYONIC FRUITFULNESS OF BUD IN THE CONDITIONS OF ANAPA - TAMAN AREA OF THE KRASNODAR REGION

abstract 1211607094 issue 121 pp. 1545 – 1582 30.09.2016 ru 185
The article presents the data on the formation of the embryonic fruitfulness of central ovaries of wintering buds of the group of technical grape varieties with white berries - White Muscat; Pinot White, Chardonnay, Citron Magaracha, Pervenets Magaracha; Riesling, Viorica, Riton, Crystal in the conditions of Anapa-Taman zone. There were revealed the rates of embryonic fruitfulness of central ovaries of buds of studied cultivars and fruiting indices of vegetative shoots developed from them. In all studied grape varieties there was revealed a high percentage of fruitful buds from 84,1 in the variety of Riton at 97.2 at Viorica; and the percentage of fertile vegetative shoots from 81,8 at the variety Citron Magaracha to 97.2 in the variety White Muscat. At the leveled load of bushes, vegetative shoots and the same scheme of planting of bushes (3 x 2 m), the highest yield in terms per hectare showed the varieties Pervenets Magaracha, Viorica, Riton, Crystal, Riesling and Citron Magarach. When assessing the economic efficiency the highest net income and level of profitability were identified in the varieties of Citron Magaracha, Pervenets Magaracha, Viorica and Riton. In order to determine which buds will give us shoots with large, well-developed (well-differentiated) buds, and which will not give (weakly differentiated), it is necessary "to look inside a bud". But even already formed germs of inflorescences in the bud are able in a few days in spring or dedifferentiate or degrade depending on the influence of external conditions. Scientists have learned to use this ability to increase the maximum possible yield in years of severe damage of grape by frosts. Firstly, in frosty winters the central buds wither out. The replacing buds usually have poor fruiting and bad productivity during years. In such cases, it is more profitable to conduct a small cutting of angle buds arranged in a circle at the base of a shoot. At the beginning of the second vegetation phase, these buds will obtain the great bulk plastic substances, which will cause the dedifferentiation of rudiments of inflorescences in them. Thus, it is possible not only to restore rapidly the normal shape of a bush, but to obtain a good harvest this year

OPTIMIZATION OF THE LENGTH OF TRIMMING AND THE LOAD OF BUSHES WITH BUDS OF DIFFERENT VARIETIES OF GRAPES IN TAMAN

abstract 1241610074 issue 124 pp. 1162 – 1181 30.12.2016 ru 260
Numerous studies have found a different quality of the buds along the length of the fruit arms, which expressed various degrees establishing embryonic inflorescences in the central buds. It is revealed that many of the grapes have more fruit-bearing eyes formed on average (4-6 knots) and upper (7 to 10 knots) levels of fruit escape, compared to the lower (1-3 nodes) layer. In connection with the different quality of the buds along the length of fruit vines should be used and different ways of cutting them. It is necessary to consider the biological characteristics of varieties, ways of doing and shaping the bushes, the weather conditions of the area during the growing season and relative calm. To receive annually a stable high yield of grapes, we must first set the optimal length of pruning fruit shoots and optimal load on the Bush healthy eyes. This requires for each class on the eve of trimming bushes to carry out the analysis of the wintering holes along the length of the fruit shoots and to identify the embryonic fruitfulness of Central buds, i.e. to carry out the prediction of grape yield next year. The article presents data on the formation of the embryonic fruitfulness of Central buds of wintering buds at the Taman group of grapes – Arcadia, Viorica, Hibernal, Cabernet Sauvignon, Merlot, Moldova, Pinot white, Riesling, Saperavi, Traminer pink, Tsimlyansky black, Chardonnay. Found higher rates of embryonic fruitfulness of Central buds buds in the studied grape varieties - Chardonnay, Riesling, Viorica, Hibernal, Merlot, Moldova, where the coefficients of fruiting ranged from 1.40 m from Riesling to 1.69 from Merlot; factor productivity of 1.58 from the Chardonnay to 1.77 from Merlo. The high percentage of fruitful buds from 80,8 from Cabernet Sauvignon to 95.6 in the cultivars Merlot and Chardonnay. A higher percentage of eyes with 2 embryonic buds in the cultivars Merlot and Viorica who have this indicator amounted to, respectively: 75,6 and 70.6%. Forecasting a crop of grapes next year to trim the bushes on the proposed method will provide a full crop of grapes

INFLUENCE OF MELAPHEN ON AGROBIOLOGICAL AND TECHNOLOGICAL CHARACTERISTIC OF SAVINION WHITE GRAPE

abstract 1211607087 issue 121 pp. 1401 – 1433 30.09.2016 ru 311
Hereby we present the results of the research devoted to study of influence of growth modulator called melaphen on the technical brand of gapes such as Sovinion White and its agro-biological characteristics. The research was conducted in 2014-2015 using fruitful grape Sovinion White of 2004 planting as a subject in agro farm “Yuzhnaya” of Temruk in the Krasnodar Region. Melaphen is a type of melamine salt of bioximethilphosphin acid. It evokes complex influence on the energetic complex of vegetation cell in all three stages of vegetation. The chemical was applied mechanically by a tractor sprinkling. The square of tested patch is 2 hectares. Melaphen usage was 6,7 ml to 1 hectare . Norm of liquid applied was 700 liters to 1 hectare. Three times the chemical was applied during vegetation: before blossoming, grape growth phase (grapes the size of a pea) and before the grapes ripen. As a result it was estimated that three times chemical application of melaphen to Sovinion White in dose 1. 10-9 in period after blossoming of grapes and before the grapes ripen led to more saturated accumulation of sugar in juice of the grapes and also to faster ripening and harvesting, larger mass of grape bunch amount of harvesting from a bush. Besides, in the tested option growing processes are accelerated and pigmentation agents are accumulated faster in the leaves and embryo infestation in winter sleeping core is boosted at larger scale. Better harvest quality leads to better wine materials quality. Application of melaphen provides higher economical efficiency

PECULIARITIES OF FORMING AGROBIOLOGICAL INDEXES OF REAL FRUITFULNESS ON GRAPE BUSHES SAPERAVI VARIETY UNDER INFLUENSE OF TREATMENT BY “VIMPEL” PREPARATION AND NEW GENERATION FERTILIZER

abstract 1161602094 issue 116 pp. 1462 – 1490 29.02.2016 ru 347
This article deals with the results of the research work concerning the influence of foliar application of grape of Saperavi variety by soluble fertilizers of new generation-Nutrivant plus and Kelik potassiumsilicon. The influence of these fertilizers on yield and actual fruitfulness have also been investigated. The experiments have been carried out both in pureform and in a tankmixture with growth regulator “VIMPEL”. The treatment by these fertilizers has been done three times in the following period; after flowering, in fruit growth phase,(pea-size berry) and in the phase of fruit maturing The foliar treatment in a pure form as well as in a tank mixture led to increase of bunch weight, harvest per bush and the yield capacity of plantation. The influence of fertilizers depended not only on variants of experiment but also on weather conditions of the previous and current year as well as on the previous yield. The negative correlation between the indexes of yield structure of the previous year and the actual fruitfulness of the current year has been revealed. However, the character of these correlative connections depends on many factors and greatly differs according to the year. As a result of these investigations, it was stated that foliar application of Saperavi grape variety by fertilizers of a new generation Nutrivant plus and Kelik potassiumsilicon in a tank mixture with growth regulator “Vimpel” in periods after flowering, berry growth(pea-size berry) and at the beginning of berry maturing did not promote a stable and significant increase of the main indexes of an actual fruitfulness. The real increase observed in all experimental variants was achieved mainly due to the increase of the average weight of the bunch

INFLUENCE OF A FOLIAR SPRAYING WITH NEW-GENERATION MINERAL FERTILIZERS ON AGROBIOLOGICAL AND TECHNOLOGICAL INDICATORS OF CHARDONNAY GRAPES

abstract 1151601041 issue 115 pp. 665 – 690 27.01.2016 ru 357
The work presents the results of studies on the influence of the foliar spraying of white grapes of the technical sort of ‘Chardonnay’ with new water-soluble fertilizers: Nutrivant plus vinograd, Kelik potassiumsilicon, Atlanta plus and microelements in chelated form - Kelkat boron, Kelkat manganese and Kelkat zinc, on its agro biological and technological indicators. The field experiment was performed in the AF Close Joint-Stock company "Primorsk" in Temryuk District. The diagram of the experiment consisted of five options: without treatment (control); Nutrivant plus vinograd - 1 kg / ha; Kelik potassium silicon - 3 kg / ha; Atlanta plus - 2 kg / ha; a set of microelements - Kelkat boron, manganese and Kelkat Kelkat zinc 660 g / ha each. It was established that the foliar spraying with these fertilizers contributes to a more intensive accumulation of sugar in the juice of berries and to the acceleration of the harvest ageing. Furthermore, the productiveness of shoots has been increased, as it is shown in a greater number of inflorescences, and sometimes, the average bunch weight increases. All this contributes to a significant increase in a yield from a bush and to a crop yield. The highest content of chlorophyll (a + b), carotinoid and the amount of pigment were observed in cases of "Atlant plus" and "Kelik potassium-silicon," where the highest sugar was contained in the berries. Foliar spraying of grapes with the complex of microelements and also Nutrivant plus and Atlanta plus contributed to the improving of the quality of wine, as evidenced by the data of the tasting degustation. The highest mark was provided by the foliar spraying of bushes using the complex of microelements

FORECASTING OF GRAPE YIELD AND THE ESTABLISHMENT OF OPTIMUM BUSH LOADING DURING THE CUTTING IN BUDS ON THE PROPOSED YIELD ON THE EXAMPLE OF OAO AF «SOUTH»

abstract 1161602026 issue 116 pp. 352 – 368 29.02.2016 ru 569
The article presents the material of forecasting for grape yield of next year and establishing the optimal loading if cutting of bushes. The material includes 14 varieties of grapes, 11 of them are technical and 3 are table ones. For each year of stable high yield of grapes, it is necessary to pre-set the optimum length of fruit cutting of shoots and optimum load on the bush healthy eyes. To do this for each variety on the eve of trimming bushes we perform optimum productivity analysis of wintering buds of fruit along the length of shoots, i.e. we implement forecasting of grape yield for next year. We have a plan of forecasting for yields of vineyards by microscopy of wintering buds on one-year shoots of fruit ripened grapes in order to establish the potential of embryonic establishment of inflorescences in the central holes of buds. Based on the analysis of buds, the indices were calculated for wintering fruiting buds and their degree of damage during the growing season. It was revealed, that the majority of grape varieties under study shows high tab embryonic inflorescences in central buds in overwintering buds for next year yield. Higher rates at a rate of fruiting buds were wintering in the varieties: Moldova (section 27). - 1.66; Bianca (section 6). - 1.83; Kunlean (section 15). - 1.71; Merlot (section 14). - 1.64; Saperavi (section 56). - 1.76. The lowest rates of fructification - the varieties Muscat Hamburg (section 21) and Augustine (section 11) and were respectively 1.20 and 1.24. As a planned productivity, we offered the optimal loading model of cutting bushes buds. As a result of productivity analyzes of buds along the length of the fruit shoots in 2016 we recommended to carry out pruning of fruit annual shoots 3-4 buds of the form of AZOS-1 and the form of cordon - 5-6 buds

OPTIMIZATION OF GRAPE GROWING TECHNOLOGY BASED ON USING THE METHOD OF YIELD PROGNOSIS

abstract 1051501061 issue 105 pp. 999 – 1033 30.01.2015 ru 594
The article highlights the questions of preliminary determination of the yield of vineyards, grape harvest prediction method to determine the optimal length of fruit cutting of shoots and load bushes wintering eyes, kidneys examined productivity index wintering buds (CP), which shows how many inflorescences have an average for each left eye escape when cutting to length, including the dead. It was found that the yield of grapes has a great influence the degree of differentiation of inflorescence of rudiments in the central buds overwintering buds. From the moment of laying the harvest of grapes in hibernating little eyes in the form of embryonic inflorescences until commercial harvest takes two growing seasons. During this period the generative organs of grape plants are affected by many factors of the environment. Heterogeneity was found of buds along the length of one-year matured shoots. It is expressed in the fact that many grape varieties fruitfulness buds at the base of the shoot are much lower compared with upstream eyes. A certain death of wintering buds (primarily, the main kidney) at the end of the growing season, before the autumn frosts. The main reason for the death of buds during the growing season - from defeat fungal diseases. Taking into account the percentage of deaths of buds proposed a new exponent forming embryonic kidney main inflorescence - productivity index of buds by the ratio of embryonic stems to the number of buds, including the dead. Thus, annual forecasting of grape harvest next year to cutting the bushes by the proposed method makes it possible to scientifically establish the optimal cut length of shoots and fruit load on the bush eyes. This helps to realize directly the potential of each variety and vineyard site and get maximum yields even in years with low fruit tab formations
