QUANTITATIVE MEASUREMENT OF THE SIMILARITIES AND DIFFERENCES OF CLONES OF GRAPES USING CONTOURS OF LEAVES WITH THE USE OF ASC-ANALYSIS AND "EIDOS" SYSTEM

abstract 1161602077 issue 116 pp. 1200 – 1223 29.02.2016 ru 628
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

REGENERATIVE PROPERTIES OF GRAPE CUTTINGS UNDER THE INFLUENCE OF TREATMENT WITH IAA

abstract 0771203099 issue 77 pp. 1190 – 1219 30.03.2012 ru 1750
The article presents the research results of eight grapes rhizogenesis of different genetic origin of the cuttings after treatment with 0.01% solution of IAA for 24 h. It was found, that the activity of regenerative processes in grape cuttings depends on the varietal characteristics, storage conditions and the activation of IAA. It leads to disruption of existing natural correlations, including suppressing the longitudinal polarity. Root-growing ability of cuttings is a genetically determined feature: the effect of IAA did not cause the stability of the positive reaction; it is determined by genotype and depends on the quality and physiological condition of the cuttings

RESEARCH OF VINE MATERIALS OF PROTOCLONES OF SAPERAVI GRAPES IN "POBEDA" JOINT-STOCK COMPANY

abstract 0530909002 issue 53 pp. 11 – 21 30.11.2009 ru 2173
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

SOME ASPECTS OF CREATION OF BASIC MOTHER LIQUIDS OF GRAPES IN THE CONDITIONS OF UST-KUNDRCHENSKY SANDY ARRAY

abstract 1351801012 issue 135 pp. 125 – 146 31.01.2018 ru 365
The generalized long-term experience on creation of base of Queen cells in grape varieties, improved in vitro culture, on the sandy array of Ust-Donetsk district of Rostov region. Problems frequently encountered on sandy soils and ways of their solution are shown. We focus on: rehabilitation of the landing of plants of grapes in the conditions of greenhouses, open ground, the optimum time and methods of planting. The work shows the effectiveness of different dressings and types of fertilizers, influence of drugs of new generation, affected the uterine protection of plantations from pests and disease, deep sandy soils freezing in winter, especially the development of root system of different varieties. On the basis of generalization of long-term data, we suggest the most appropriate solutions, and developed technology bookmarks and conducting basic queen cells from healthy in vitro planting material of grapes in the sandy array

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

abstract 1341710026 issue 134 pp. 303 – 327 29.12.2017 ru 971
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"

STUDY OF AROMATIC CONTENT OF DIFFERENT BRANDIES MADE IN ARMENIA

abstract 0981404068 issue 98 pp. 942 – 948 30.04.2014 ru 1472
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
