STUDY OF AROMATIC CONTENT OF DIFFERENT BRANDIES MADE IN ARMENIA
06.00.00 Agricultural sciences
Description
Brandy alcohols from the grades of Muscat Berkatu, Kakhet and mixes of white grades of grapes became objects of researches. The content of some aromatic components of wine alcohols was investigated using the device of a gas-liquid chromatography Clarus-400 (with the ardent and ionization detector, a capillary column, 60 m x 0,32 mm, Elite-WAX ETR, gas-carrier-helium). Muscat alcohol according to the general content of aromatic substances (919,35 mg / 100 ml a.a.) was different from the other studied samples at the expense of the high content of ethyl acetate and izoamyl alcohol. As a result of the organoleptic analysis of a blend samples it was allocated a brandy blend with the following ratios of alcohol and wine - a blend alcohol – 74,37 %, liqueur wine – 25,63 % with strong muscat aroma and shades of taste

RESEARCH OF VINE MATERIALS OF PROTOCLONES OF SAPERAVI GRAPES IN "POBEDA" JOINT-STOCK COMPANY
06.00.00 Agricultural sciences
Description
In this article chemical and technical characteristics questions of vine materials, received from protoclones of grapes of Saperavi grade - one of the basic classical grades of grapes selected in "Pobeda" Joint-Stock Company are taken up. Samples of grapes have been used for preparation of red table wines by mash fermentation on septum in workshop of micro winemaking of The North Caucasian zone scientific research institute of gardening and wine growing. They have not given vine materials identical on physical and chemical and organoleptical features. Samples with low productivity essentially differed on organoleptical qualities from other samples and had the highest sampling estimations that allows to take measures on loading regulation on a grape bush and correct quality of wine in further by means of methods of agricultural technics. For making high-quality table red vine materials it is recommended to use apple-lactic fermentation by means of oxygen-eating bacteria

THE RESEARCH OF HAPLOTYPE DEVERSITY OF RUSSIA ABORIGINAL GRAPE VARIETIES
06.00.00 Agricultural sciences
Description
In the article we have studied 55 aboriginal varieties, collected in the North Caucasus. We have described allelic diversity and identified four haplotypes. All the populations were closely related while being examined using a factor of Nei's genetic distance (Dn), with the exception of indigenous varieties of Armenia. Maximum differences have been found between the Uzbek population and Astrakhan, Turkmenian, Armenian populations. The most genetically rich were the population of Don area and Krasnodar region

THE RESEARCH OF VITIS SILVESTRIS GMEL. IN THE NOTHERN CAUCASUS
06.00.00 Agricultural sciences
Description
Vitis vinifera subsp. silvestris Gmel. is the wild subspecies of Vitis vinifera L. and an important source of genetic resources for grapes breeding. Currently, this form is very rare in the world. In this paper, conducted the first study of wild grapes which was found in the North Caucasus with the use of two microsatellite markers. The study have shown a high level of genetic diversity: intrapopulation variability was 75,2%, the interpopulation variability accounts was 24,8%. All populations are characterized by certain unique genetic structure and may be as donor of resistance genes which have a long-term evolutionary selection

Description
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)

Description
The article discusses the application of automated system-cognitive analysis (ASC-analysis), its mathematical model is a system of information theory and implements, its software tools – intellectual system called "Eidos" for solving one of the important tasks of ampelography: to quantify the similarities and differences of different clones of grapes using contours of the leaves. To solve this task we perform the following steps: 1) digitization of scanned images of the leaves and creation their mathematical models; 2) formation mathematical models of specific leaves with the application of information theory; 3) modeling the generalized images of leaves of different clones on the basis of specific leaves (multiparameter typing); 4) verification of the model by identifying specific leaf images with generic clones, i.e., classes (system identification); 5) quantification of the similarities and differences of the clones, i.e. cluster-constructive analysis of generalized images of leaves of various clones. The specific shape of the contour of the leaf is regarded as noise information on the clone to which it relates, including information about the true shape of a leaf of this clone (clean signal) and noise, which distort the real shape, due to the random influence of the environment. Software tools of ASA-analysis which is intellectual "Eidos" system provides the noise suppression and the detection of a signal about the true shape of a leaf of each clone on the basis of a number of noisy concrete examples of the leaves of this clone. This creates a single image of the shape of the leaf of each clone, independent of their specific implementations, i.e. "Eidos" of these images (in the sense of Plato) - the prototype or archetype (in the Jungian sense) of the images
