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 510
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

abstract 1301706090 issue 130 pp. 1236 – 1248 30.06.2017 ru 305
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)

STRUCTURAL AND PHYLOGENETIC ANALYSIS OF VVMYBA1, VVMYBA2 AND VVMYBA3 GRAPEVINE GENES

abstract 1341710026 issue 134 pp. 303 – 327 29.12.2017 ru 837
The article presents the structural and phylogenetic analysis of VIT_02s0033g00410, VIT_02s0033g00390 and VIT_02s0033g00450 genes of the grapevine genome and the closely related orthologous gene MYB114 of the Arabidopsis genome. These genes are responsible for the biosynthesis of anthocyanin in the organs of model plants and are of interest not only for practical production and breeding, but also for fundamental research. These genes were analyzed for GCcomposition of nucleotides, the presence of cisregulatory elements and promoter regions. DNA and protein sequences were aligned to look for similar elements, which allowed further analysis of the ultraconservative domains of four genes. Based on the results of search and identification of the conservative regions, a cluster tree was constructed, which made it possible to identify the separation of gene sidelines from, presumably, the main one. At the same time, the construction of consensus trees based on DNA and protein sequences revealed their absolute similarity. "The Minimal Evolution Tree" allowed calculating the approximate dates of the appearance of the mutations and the divergence times of the gene branches between each other. At the same time, the appearance of the Vitis genus and its separation from the Rosales was taken as the time first divergence point. In the end, homologous metabolic pathways were searched between grapevine and Arabidopsis, which revealed the presence of homologous proteins in the grape proteome. In this turn, it already confirms the existence of similar biosynthetic pathways and, as a consequence, interactions such as "DNA-protein" and "protein-protein"
