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 552
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

FROST RESISTANCE OF CRIMEAN INDIGENOUS GRAPE VARIETIES AND THEIR HYBRIDS

abstract 1171603044 issue 117 pp. 684 – 697 31.03.2016 ru 274
The article highlights the issues of grape plants resistance to low temperatures; it is an urgent problem for all wine-growing regions of the world, located in the zone of risky agriculture. Losses caused by frost, indicate long-standing necessity of perfection of assortment in terms of enhancing its hardiness by enriching more resistant genotypes obtained both through the introduction or naturalization, as well as from the crossing of indigenous with interspecies hybrids. Methodology for evaluating frost resistance properties of the material served as a preparation for the originality of his research and experimental evaluation of the unique divisibility properties of the aim. Thus, we initially conducted hardening of matured cuttings at positive temperature plus 8 plus 4 ° C for 14 days (I quenching phase) and a negative temperature minus 5 ° C-minus 7 ° C for 9 days and minus 10 ° C-1 day (II hardening phase). Then the cuttings we frozen in the temperature range from minus 16 ° C to the next steps of consistent freezing (minus 16 ° C - 2 days; minus 18 ° C - 2 days; minus 20 ° C - 2 days; minus 22 ° C – 1day, minus 24 ° C - 1 day, minus 26 ° C - 1 day, minus 28 ° C - 1 day and minus 30 ° C - 8 hours). After freezing of cuttings of each variety, the sample was placed on the 3 days in the refrigerator at the temperature of + 2 ° C to their gradual thawing. Cuttings were grown at room temperature on water. As a result, obtained by the accounting: the lowest frost-resistance among the studied forms of parental Crimean origins was found in grades of Shabash, Soldayya and Solnechnodolinsky; the varieties of Dzevat kara, Kokur bely, Kokur cherny, Misket, Misgyuli kara, Sari Pandas were set as a weak level (-20 °C); Aybatly, Kefesiya, Kok pandas and Ekim kara have average level up to -22 °C; the highest frost-resistance - 24 °C – was shown by Khersonessky and Kapselsky. Also, we have identified synthetic frost-resistant F1-population and plus-transgressive selection form

GRAPEVINE PLANT REGENERATION FROM CELL SUSPENSIONS AND INFLORESCENCE FORMATION IN VITRO UNDER THE INFLUENCE OF DIFFERENT VITAMIN AND MINERAL ELEMENT LEVELS IN NUTRIENT MEDIA

abstract 0500906010 issue 50 pp. 112 – 130 29.06.2009 ru 2848
Effects of different levels of vitamins (thiamine, pyridoxine and nicotinic acid) and macro-elements (MS, NN and PG) on development of globular, heart- and torpedo-stage embryos and plantlets with green cotyledons and on shoot production from them were studied in grapevine interspecific hybrids: cvs. ‘Bianca’, ‘Podarok Magaracha’ and ‘Intervitis Magaracha’. Pro-embryogenic calli were derived from petiole explants on solid full-strength NN medium supplemented with different levels of 2,4-dichlorophenoxyacetic acid (2,4-D) and 6-benzyladenine (BA) for each cultivar and used to initiate cell suspensions in liquid NN medium supplemented with 1 mg L-1 2,4-D and 0.2 mg L-1 BA. The following formulations of media were optimal for different stages of somatic embryogenesis and for plantlets with green cotyledons development: liquid NN medium supplemented with 0.5 mg L-1 BA  for globular embryo formation; liquid HTE medium (with PG macro-elements, thiamine and pyridoxine at 5 mg L-1 each and 0.5 mg L-1 nicotinic acid): supplemented with 0.2 mg L-1 BA  for heart-stage embryo development, supplemented with 0.1 mg L-1 indole-3-acetic acid (IAA) and 30 mg L-1 sodium humate  for torpedo-stage embryo development and supplemented with 0.5 mg L-1 gibberellic acid (GA3)  for the growth of plantlets with green cotyledons. Solid MS medium modified by the addition of nicotinic acid, pyridoxine and p-aminobenzoic acid (PAB) at 5 mg L-1 each, 0.5 mg L-1 thiamine and 0.5 mg L-1 BA was best efficient for shoot production from plantlets. Inflorescence formation in regenerated plants of cv. ‘Podarok Magaracha’ grown on solid hormone-free PG medium was induced by addition of nicotinic acid, pyridoxine and PAB at 5 mg L-1 each, 0.5 mg L-1 thiamine and 0.2 mg L-1 BA into liquid modified HTE medium for growth of plantlets with green cotyledons and into solid modified MS medium for shoot production from them.

HISTORICAL FRAGMENTS OF ESTABLISHMENT OF "MAGARACH" SCIENTIFIC INSTITUTE OF GRAPES AND WINE AND THE ELEMENTS OF ITS SCIENTIFIC ACTIVITY

abstract 1131509085 issue 113 pp. 1179 – 1209 30.11.2015 ru 727
The article presents historical information about the stages of gradual transformation of the first non-large wine-making institution of Crimea, organized in 1828 under the initiative of Prince M.S. Vorontsov in the natural boundary called Magarach near the Imperial Nikitsky botanical garden in the world famous Institute of Grape and Wine "Magarach" - once the chief coordinator of the research work in the field of viticulture and winemaking republics of the USSR and the main forge of scientific staff in this direction. Among the directors of the institute of the last century, there were such talented organizers as A.G. Globa, T.G. Kataryan, P.Y. Golodriga. The Institute operated a network of regional branches, created enotec with a settled in 1836 wine Muscat pink Magarach (World rarity is reflected in the Guinness book of records), the world ampelographic collection (fourth in number of samples), scientists developed area-standard assortment for production, issued 11 Volumes of "Ampelography of USSR" (awarded by OIV), designed a lot of outstanding for yield and stability varieties (Pervenets Magaracha, Ranniy Magaracha, Citron Magaracha et al.) and clones (Muscat white of Red Stone, Pinot Noir yields and others.) grapes. There was a significant contribution in the sphere of research and development of viticulture and winemaking of world, the institute was given an international prestige and this led to establishing the base of the General Assembly of the OIV - International Organization of Grape and Wine, the International Symposium on the selection of wine-town, several international wine tasting competitions and International finest examples of table grapes
