Kormilitsa Lisa grape was created in Greece by P. Zamanidi and L.Troshin in 2003 with crossing the varieties of the Pervenets Maharach with varieties of Muscat white. The duration of the production period is 146-155 days. The yield is high. The average mass of clusters of 250 g. It has winter hardiness, drought-resistance and high resistance to fungal diseases in comparison with varieties of Vitis vinifera; it is also tolerant to phylloxeras. The flower is ambisexual. The bunch is average, cylinder-conic, medium density. The berry is average, oval, green-yellow colour, with a thick wax coating. The skin is thin, thick, and strong. The pulp and juice with a strong Muscat flavor. Sugar content is high with acidity constant. When overripen, it dries long and is stored on the bushes. The variety is meant for manufacture of dry white wine of superior class and high-quality dessert and sweet wines; It is also suitable for the development of high-quality juices and compotes
In the article we have studied 55 aboriginal varieties,
collected in the North Caucasus. We have described
allelic diversity and identified four haplotypes. All the
populations were closely related while being examined
using a factor of Nei's genetic distance (Dn), with the
exception of indigenous varieties of Armenia.
Maximum differences have been found between the
Uzbek population and Astrakhan, Turkmenian,
Armenian populations. The most genetically rich were
the population of Don area and Krasnodar region
In the article we show the investigations of aromatic wine produced from grapes of Sauvignon blanc grown in AF South in Temryuk District. As a result, the article estimates obtained good organoleptic characteristics of the taste, within 7.3-7.9 points, which is higher than the passing score. It was found that the greatest negative impact on the formation of mutual organoleptic properties have such flavors as metilatse-tal and the amount of volatile acids
The variety "Professor Maltabar" is new,
it is growth in Greece by Pantelei Zamanidi
and Leonid Troshin in 2001 year from crossing of Aigeorgitico and Cabernet Sauvignon. The variety belongs to the group Black sea basin (convar. orientalis subconvar. caspica Negr.).
The production period is 146-156 days. The yield is higher. The bunch weight is 200 g.
The bunch is middle, cylinder conical or winged, middle density. The berry is middle, round, blue-black color. The skin is density, the pulp is juicy, the sap in not colored, with solanum after-taste. The sugarnesses is higher. The quantity of seeds is two-three.
The seed is middle, grey color, piriform, with shot beak. It is higher steadiness variety for winter frost, drought-resistance and higher steadiness for mushrooms disease compare with it’s parents.
The variety is used for preparing higher quality dry red, pink and white (champagne) wines of different categories.
Nutrient media for shoot development from shoot tips 0.5-0.8 mm with several leaf primordia in four grapevine genotypes were optimized by means of a mathematical design of experiment. Over the range of component concentrations CaCl2 had considerable the highest effect on shoot tip development compared to other components of the media. Grapevine genotypes were different in their needs for concentrations of macro-elements to optimize the process of their growth and development. Shoot development from shoot tips in each grapevine genotype as a function of macro-element concentrations in media must be described by an individual regression equation. The proposed method of result evaluation and the mathematical design of experiment may be used in physiological and agricultural research for optimization of processes affected by numerous factors. The optimized media for shoot tip development may by used for sanitation of grape plants from viruses in meristem cultures
In this innovational section the results of two-year test of technology of influence of biologically active substances "Rostock", "Kremniy", «Lignogumat kaliya» and "Zircon", and also water activated through the matrixes of these substances by means of "Akvator" device grape plants of Bianka variety are presented. Researches have shown, that the water activated by "Akvator" device, possesses surprising abilities, its influence on a grape plant exceeds influence of BAS solutions more than in 1,3 times by efficiency
In this article we have described a study of genotyping of new three productive wine grapes protoclones: Rhine Rieslin, Verdot black and Johanniter
In this article botanical and morphometrical characteristics of four wild-growing biotypes of Azerbaijan, growing on the Nakhichevan plain - original natural reserve of the richest vegetable gene pool of Eurasia are listed. Unique lianas are discovered, featured and listed under titles of Ajryndzh, Dary-dag, Ilandy-dag and Ordubad. Their comparison on 40 arguments of leaves with reference Vitis vinifera silvestris Gmel. triune herbarium of Russia and Ukraine is resulted
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
The paper reviews the results of the study in in Anapо-Taman zone Krasnodar territory e of influence treatment vines Saperavi growth promoters Immunotsitofit, Krezatcina and HB-101ECO on quality parameters wine
