06.00.00 Agricultural sciences
Description
Introduced grape varieties such as Ancelotti, Bachka, Johanniter, Morava and Solaris which were grown in the conditions of Taman provided production of high yields of grapes with standard conditions of sweetness and acidity of grape juice that were useful for the technical processing of not only tableware, but also for special wines, in particular, dessert. Organoleptic properties of all the studied wine materials from grapes of these varieties were of high quality, which was con-firmed by their tasting evaluation. They are recom-mended for the preparation of organic (bio) wines. The "Biologik" wine in 2012 received a certificate of the high points at the international exhibition in Italy (Rome), and the wine from red grape variety Ancelotti for several years, winning awards from international wine competitions ("Yalta. Gold Griffon", "Gold au-tumn")

APPLE ROSETTE DISEASE IN NORTH CAUCASUS PLANTATIONS
06.01.01 General agriculture, crop production (agricultural sciences)
Description
The article presents the results of a study of the apple tree rosette disease found in a collection garden and having a viral nature. The rosetting has typical signs of manifestation. Sick plants develop narrow small chlorotic leaves. Rosettes of leaves on the upper cervical and lateral shoots are formed as a result of the convergence of internodes. The spread of the rosetting in the planting reaches 10-11 %. The prevalence of viral disease varies among the 44 varieties of apple trees of different ecological and geographical origin. So, the lesion of rosetting was noted on single trees in the varieties of Gala Redi Red, Fujiko, Red Free, etc., and it was a complete defeat in the variety of Piros. A different degree of the manifestation of the disease on the trees was established: from partial manifestation on individual shoots, to aggressive damage to the entire crown of the tree. On young trees bearing fruiting (3-4 years from planting), the rosetting reduces the yield of apple trees by 36 %, ¼ part of the fruits on the trees are small in size compared to the fruits of healthy trees. The infectious nature of the rosetting is confirmed by the transfer of the disease on the most affected Piros variety using summer budding

INTRODUCTION OF NEW GRAPES VARIETIES TO THE IN VITRO CULTURE
Description
Clonal micro-multiplication – is this the basic method of obtaining the qualitative virus-free planting material. The high quality specificity of the explants reaction of the grapes varieties to the composition of nutrient medium requires the individual selection of the medium components for the most successful multiplication in vitro. In the article we present the results of studies on the cultivation of the grapes apexes in vitro the modified medium with the reduced content of macrocells. As a result of conducted investigations we have established that for the grapes varieties of Academic Trubilin, Artemis, Gurman Kraynova, Maria Kallas, Nizina, Petit Verdo and Traminer Black the most effective introduction into the in vitro culture (acclimatization of apexes 80- 100%) occurs on modified nutrient medium to Murasige and Skoog (1962), by being differed in terms of the content macro-elements (mG/l): NH4NO3 – 1237; KNO3 – 1425; MgSO4 · 7N2O – 277,5; KN2PO4 · H2O – 277,5, of the vitamin Of v1 – 10,0 mG/l, nicotinic acid – 4 mG/l. Remaining varieties of Kishmish luchistiy, Preobrajenie, Roshfor K and Yubiley Novocherkasska in the same medium were developed slowly and in a different way

VARIETY OF MICROORGANISMS GROUPS LIVING ON BERRIES OF GRAPES
Description
The wide variety of microorganisms has been identified in many wine-making countries on the berries of grapes. These are yeasts of different families, forms and kinds, bacterium, mold fungi. In the article, we present the results of investigating species composition of microflora of berries of white and red types of grape, which grows in different economies of the Krasnodar region and the republic of Abkhaziya. The sowings onto the elective media were conducted for the development of entire spectrum of yeast. The grown colonies after preliminary microscoping were separated into the cultures and subjected to testing according to the culturalmorphological signs, being guided by determinants and benefits. It was established the specific variety of microflora on the surface of the berries of grapes of all investigated types, without dependence on the place of their growth. Obtained data showed that the group of yeast, which constantly is present in the complex of the epiphytic microorganisms of grapes of Saccharomyces, Pichia, Hansenula, Hanseniaspora was characteristic for all types of grapes in all investigated regions. The heterogeneity of the taxonometric composition of microflora is shown. Prevailed yeasts were of family Saccharomycetaceae, form Saccharomyces vini. A quantity of yeast of Saccharomyces vini decreases in a number of Myskhako-Caucasus-Fanagoriya, that as a whole will be coordinated with the climatic conditions. Only the type of Pinot nuar grapes had yeasts of Brettanomyces Dekkera. On the berries of Cabernets and Karaburnu we have discovered yeasts of Schisosaccharomyces acidodevoratus, causing acid-reduction. On the berries of the grapes, which grew in joint stock company APF “Fanagoriya” we haven’t revealed the presence of lactic acid bacteria Lactobacillus brevis and yeasts of the form of Schisosaccharomyces acidodevoratus. In the same farm the smallest quantity of yeastswreckers is noted, which we the forms of Pichia and Candida. In the microflora of Cabernets, Risling and, especially, Karaburnu grapes, we have found lactic acid bacteria Lactobacillus plantarum and Lactobacillus brevis. Lactobacillus plantarum. Among the bacteria the total quantity of coccic flora composes - 56 %, the rod-shaped - 44 %. Two types of active acetous bacteria are identified – Acetobacter aceti and Acetobacter xelinum. Especially high was their surface concentration on the berries of Kachich type of grapes

06.01.01 General agriculture, crop production (agricultural sciences)
Description
In the article, we have studied the influence of biological nitrogen deposition on the physical and chemical parameters of natural semi-sweet wine, on the example of two grape varieties – classic European Chardonnay and interspecific hybrid Ekaterinodar, including amino acids and aroma-forming components. It is established, that the use of the proposed technology contributes to the active consumption of amino acids by yeast in the fermentation stage. At the same time, yeast cells consumed most actively alanine, valine, phenylalanine, histidine, aspartic, aminobutyric, glutamic acids, leucine, lysine, Sirin, tyrosine, threonine. A slight increase in the concentration of amino acids was observed at the end of fermentation, when the yeast cells entered the stationary phase of development. However, the content of all amino acids, with the exception of Proline, in the wine material was less than in grapes and fermenting wort. As a result of biological nitrogen deposition in experimental versions, the concentration of nitrogen compounds (total and amine nitrogen) was three times less than in the control ones. There is a difference in the concentration of flavor-forming components in wines prepared from both grape varieties using different technologies. In experimental versions, we observed a greater accumulation of almost all components of the aroma-binding complex (especially esters, terpenes, phenylethanol, and ionone), with the exception of higher alcohols. Experimental samples of natural semi-sweet wines from the Chardonnay and Ekaterinodar grape varieties were characterized by a bright floral and fruit aroma and had a higher tasting rating in comparison with the classic technology

Description
The article presents results of the assessment of the efficiency of non-hormonal preparations which were not earlier applied in culture in vitro with high physiological activity (the preparations received by production of furfural, and also derivatives and compositions of organic acids) during regenerations of microshoots of plum, comparison of their influence with influence of growth regulators which are traditionally used in clonal micropropagation. These experimental preparations were received when processing waste of agricultural production. In this work we used: technology of clonal micropropagation of plants of in vitro, statistical data processing by method of the dispersive analysis. The objects of researches were microshoots of plum of a Stanley variety. We have established that on mediums with the preparations "Universal", sodium succinate, potassium succinate, amber acid, L-1 the large, intensively colored plum microshoots develop surpassing control (medium with BAP of 1 mg/l, IBA of 0,1 mg/l, gibberellic acid of 0,5 mg/l) in morphometric parameters. Thus, the preparations "Universal", sodium succinate, potassium succinate, amber acid, L-1 in concentration of 4,0 mg/l proved as the growth factors which are favorably influencing on plantlets’ regeneration and a qualitative condition of microshoots of plum
