THE QUALITY OF MERLOT GRAPE AND WINE ON A BACKGROUND OF APPLICATION OF MINERAL FERTILIZERS IN THE CONDITIONS OF ANAPA-TAMAN AREA

abstract 1301706090 issue 130 pp. 1236 – 1248 30.06.2017 ru 274
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)

THE RESEARCH OF VITIS SILVESTRIS GMEL. IN THE NOTHERN CAUCASUS

abstract 0581004021 issue 58 pp. 324 – 335 28.04.2010 ru 2261
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

THE SOLUTION OF PROBLEMS OF AMPELOGRAPHY BY USING ASC-ANALYSIS OF IMAGES OF LEAVES IN THEIR EXTERNAL CONTOURS (GENERALIZATION, ABSTRACTION, CLASSIFICATION AND IDENTIFICATION)

abstract 1121508064 issue 112 pp. 858 – 906 30.10.2015 ru 496
The article discusses the use of automatic systemic-cognitive analysis (ASC-analysis), its mathematical model is a system of information theory and software tools – an intellectual system called "Eidos" for the solution of some problems of ampelography: 1) digitization of scanned images of the leaves and creation of their mathematical models; 2) the formation of mathematical models of specific leaves using the spreading of information theory; 3) the formation of models of generalized images of leaves of various sorts; 4) comparing an image of a specific leaf with a generalized image of the leaf of different varieties and finding a quantitative degree of similarity and differences between them, i.e. the identification of the varieties on the leaf; 5) quantification of the similarities and differences of the varieties, i.e. cluster-constructive analysis of generalized images of the leaves of different varieties. We propose a new approach to digitizing images of leaves, based on using the polar coordinate system, the center of gravity of the image and its external contour. Before scanning images we may use transformation to standardize the position of the still images, their sizes and rotation angle. Therefore, the results of digitization and ASC-analysis of the images might be invariant (independent) relatively to their position, size and rotation. The specific shape of the contour of the leaf is regarded as noise information on the variety, including information about the true shape of the leaf of the class (clean signal) and noise, which distort this true form, originating in a random environment. Software tools of ASC-analysis – intellectual "Eidos" system ensures noise reduction and the selection of the signal about the true shape of the leaf of each variety on the basis of a number of noisy concrete examples of the leaves of this variety. This creates a one way form of a leaf of each class, free from their concrete implementations, i.e., the "Eidos" of these images (in the sense of Plato) is a prototype or archetype (in the Jungian sense) of the images

THE STUDY OF GRAPE GENETIC DIVERSITY OF THE NORTH CAUCASUS GENE POOL

abstract 1191605090 issue 119 pp. 1337 – 1355 31.05.2016 ru 428
The article presents the results of studies of 92 indigenous varieties and 15 wild genotypes by 24 microsatellite markers. As a result a locus database about germplasm in the collection stored at the Russian ampelographical collection AZOSViV (Anapa Zone Experimental Station of Viticulture and winemaking) was created. During the research of varietal breeding populations confirmed the validity in the production of the cultivar of Krasnostop anapsky with obvious changes in microsatellite sequences as a clone of famous indigenous Don cultivar Krasnostop Zolotovskii. This clone was selected in 1953 by prominent agrotechnologist Zotkin Ivan Ivanovich which is propagated by the author and his followers, and after a formal registration submitted to state testing in 2007 in GSK RF, zoned in the North Caucasus region (number 6) in 2014 year. Sort -clone Krasnostop anapsky only in the Kuban today cultivating in 35 hectares. By using molecular genetic techniques, now clonal selection of vine grapes is reasonably improving. Recent data collected by us in the work process, were analyzed a comprehensive manner, making it possible to draw conclusions about distinctness of grape varieties. Some clones were studied by DNA primers, based on retrotransposon sequences
