The newest wine grape variety Eftihiya with aromatic pink colored skin (in Greek the name means “happi-ness”) was breed with hybridization at the Athens In-stitute of Viticulture by P. Zamanidi, L. Troshin and P. Radchevskiy in 2005 by crossing the Greek varieties and Malaguzya with Eurasian Traminer pink. Dura-tion of production period from bud burst to harvest 146-155 days. Yields are very high: 25-30 t / ha. Modal mass of clusters is 250 g. Bunch is conical, me-dium density. Berry is medium, short elliptical, pink colored, with a thick wax coating. Pulp and juice with the expressed varietal flavor, similar to the aroma of Traminer pink. Sugar content of more than 24%. Vari-ety is designed for production for the dry white wines of excellent class and high-quality sparkling, dessert and sweet wines; suitable for the production of high quality aromatic juices
The article presents data on the formation of the embryonic fruitfulness of central buds of wintering buds grapes of different origins in the period of relative calm of grapes and early spring period in dynamics with presence of positive air and soil temperatures
The article presents the results of three years of studies
on regenerative processes in technical white one-bud
cuttings of resistant varieties of grapes Bianca, Viorica
and Riton. The studies were conducted in greenhouse
experiments at the Department of Viticulture of Kuban
State Agrarian University. It was found, that the
cuttings of Viorica varieties had achieved the best
ripening, and the worst was Bianca. Varieties of
Viorica and Ryton which have rather good level of
ripening of the cuttings, had starch in carbohydrates
and Bianca variety had sugar. Earlier blooming of
buds characterized the cuttings of Ryton. Blooming of
the buds of Bianca somewhat delayed. Maximum
length of the shoots characterized the cuttings of
Bianca, and the lowest – Viorica. The shortest pre-root
period (26.3 days) was observed in Ryton, and the
longest (29.3 days) – in Bianca. Viorica was
characterized by the highest yield of cuttings with 3
roots and more (81.3%), this indicator was a bit less
(72.5%) for Ryton. For Bianca it was minimal and it
was 26.3%. A similar pattern was observed for the
average number of cuttings formed at the roots: the
variety Viorica - 9.4 pc.,Ryton - 8.1 pc. and Bianca -
4.3 pc. Thus, cuttings of the varieties of Viorica and
Ryton belong to a group with a very high root growing
activity and Bianca has an average activity
The article presents the results of three years of
researches conducted at the Department of Viticulture
of Kuban State Agrarian University, to study the
processes of shoots and rooting of the three-bud
cuttings of grapes of Pervenets Magaracha, Podarok
Magaracha and Cytrony Magaracha of the selection of
Magarach Institute of Grape and Wine. The area of
these varieties, which are inter-specific hybrids, in the
Krasnodar region is more than 2 thousands hectares.
The cuttings were rooted in sawdust in a greenhouse
on a heated rack. It was found, that the regenerative
capacity of cuttings was strongly dependent on the
method of their storage prior to installation on the
germination. The best results were obtained in the case
when cuttings had been stored in the refrigerator
before starting the experiment. The lowest impact of
the way to store cuttings was on the percentage of
cuttings with blossoming eyes, and the largest - the
length of the shoots, the output of the cuttings with at
least 3 of the roots, and the average number of roots
developed on one cutting. Rooting of cuttings and
their growth with three and more roots were different
over the years for the varieties of Pervenets
Magaracha and Cytrony Magaracha, in favor of one
sort or another, but the average 3-year difference
between varieties was not significant. On average, in
two or three years, the maximum number of roots
appeared in the variety of Cytrony Magaracha, which
was a bit ahead of Pervenets Magaracha. The
difference in the number of cuttings formed at the
roots was authentic. Correlation analysis showed that
the closest relationship to the performance of the
rooting ability of cuttings was found in the length of
the shoots. The level and the nature of the identified
correlations suggests that the rooting ability of the
cuttings of the varieties of Pervenets Magaracha was
determined primarily by hormonal activity, Podarok Magaracha by its supply of plastic substances, and
Cytrony Magaracha had equally both factors
The article presents the results of the research on the
effect of processing cuttings grapes Moldova and
Bianca by a growth regulator called Stimolant 66f
(Stimolante 66f) on their regenerative properties, the
yield and quality of seedlings. In Moldova grade, we
tested three concentrations of the drug - 0.001; 0.01
and 0.1% and grade Bianca - five - - 0.001; 0.005;
0.01; 0.05 and 0.1%, compared to treatment with IAA
(standard) or without treatment (control). It was found,
that both types of processing cuttings with IAA led to
the inhibition of blooming buds. Application of
Stimolanta to both varieties accelerated blooming
buds, and to the greatest extent on grade Bianca. On
the variety Moldova, the processing cuttings with
heteroauxin and Stimolant at 0.01 and 0.1% had an
inhibitory effect on the growth of shoots, which
survived to the end of the experiment. On the variety
of Bianca, both the IAA and Stimolant at all
concentrations of working solution contributed to a
significant increase the length of the shoots. At grade
Moldova, basal ends of cuttings treatment for 24 hours
in solutions of Stimolanta at 0.01 and 0.1%
concentration had the root-growing ability stimulated,
enhanced the yield and quality of seedlings. In grade
Bianca, better rooting of cuttings with 3 or more roots
was observed in the variant of "Stimolant - 0.05%",
and a greater number of roots were produced in the
version of "Stimolant - 0.1%." In cuttings of varieties
ofMoldova, Stimolant showed better results than the
IAA in optimal concentrations, and grade Bianca had
about the same results
The article is dedicated to the features of the correlations between the indicators of shoot and root growth ability of grape cuttings varieties of Moldova and Vostorg of different lengths, under the influence of the processing them with Norwegian growth regulator - Radix plus. We have found that in the control variants on both varieties there are fairly close correlation connections between the number of shoots, their length and the degree of blooming buds. However, in the advanced options the character of the relationship between these parameters depends on the varietal characteristics manifested in the potential root activity cuttings. For Moldova cuttings which are characterized by high root activity, the use of Radix plus led to some strengthening of the correlations, and for Vostorg (with the weak activity of rooting of cuttings) - to decreasing of the correlations. This fact may indicate that the negative effects of growth regulators on the activity of endogenous hormones in the cuttings of Vostorg varieties, which explains the decrease of rooting of longer cuttings. Processing the cuttings of Moldova with Radix plus led to increasing in the frequency and extension of the correlations between shoot and root growth ability of cuttings. For Vostorg, on the contrary, the use of Radix plus led to the weakening of these connections. The reason for this phenomenon, as is the case with figures of shoot growth ability may be a change in the activity of the endogenous phytohormone influenced by exogenous auxin. Character of correlations identified between indicators of root growth ability of cuttings shows that rooting depends primarily on the hormonal activity of cuttings, number of roots - on cuttings plastic substances, and the yield of cuttings with 3 roots and more - on both of these points
The work presents the results of studies on the
influence of the foliar spraying of white grapes of the
technical sort of ‘Chardonnay’ with new water-soluble
fertilizers: Nutrivant plus vinograd, Kelik potassiumsilicon,
Atlanta plus and microelements in chelated
form - Kelkat boron, Kelkat manganese and Kelkat
zinc, on its agro biological and technological
indicators. The field experiment was performed in the
AF Close Joint-Stock company "Primorsk" in
Temryuk District. The diagram of the experiment
consisted of five options: without treatment (control);
Nutrivant plus vinograd - 1 kg / ha; Kelik potassium
silicon - 3 kg / ha; Atlanta plus - 2 kg / ha; a set of
microelements - Kelkat boron, manganese and Kelkat
Kelkat zinc 660 g / ha each. It was established that the
foliar spraying with these fertilizers contributes to a
more intensive accumulation of sugar in the juice of
berries and to the acceleration of the harvest ageing.
Furthermore, the productiveness of shoots has been
increased, as it is shown in a greater number of
inflorescences, and sometimes, the average bunch
weight increases. All this contributes to a significant
increase in a yield from a bush and to a crop yield. The
highest content of chlorophyll (a + b), carotinoid and
the amount of pigment were observed in cases of
"Atlant plus" and "Kelik potassium-silicon," where the
highest sugar was contained in the berries. Foliar
spraying of grapes with the complex of microelements
and also Nutrivant plus and Atlanta plus contributed to
the improving of the quality of wine, as evidenced by
the data of the tasting degustation. The highest mark
was provided by the foliar spraying of bushes using
the complex of microelements
The article presents the results of the fertilizers use effect on dry wine materials produced from the Chardonnay variety, grown in the Anapo-Taman soil and climatic zone of the Krasnodar region, Russia. As a result of wine materials analysis, increase of tartaric acid was noted, with the autumn application of phosphorus-potassium fertilizers and the spring application of ammonium nitrate. At the same time, its optimum content was noted with nitroammophos. Also, the minimum concentration of malic acids was detected by the application of nitroammophos with potassium fertilizers. In its turn, early spring application of ammonium nitrate reduced the concentration of malic acid below the control sample (without fertilizers). It was revealed that the use of mineral fertilizers in this winemaking zone also contributed to a reduction of lactic acid in the must. At the same time, the application of nitroammophos (especially together with other mineral fertilizers), contributed to the accumulation of citric and succinic acids, as well as phenolic compounds. Moreover, the application of phosphate-potassium fertilizers in the autumn contributed to the accumulation, and, consequently, also to the increase in the content of phenolic compounds in the resulting must. In addition, the studied samples of wine materials contained high alcohol concentrations and low concentrations of sugars with volatile acids. At the same time, the maximum amount of alcohol exceeding its content in the control sample was revealed when phosphorus-potassium fertilizers were used together with nitroammophos fertilizers. It is also noted that the application of ammonium nitrate did not affect this indicator. As a result, the use of mineral fertilizers in the studied concentrations made it possible to prepare wine materials that contained a low concentration of sulfur dioxide, which is substantially lower than the harmful concentration for humans. In addition, increased concentrations of hydrogen ions in variants with the application of phosphate-potassium fertilizers have made it possible to reduce the number of iron tanates and the intensity of oxidation-reduction processes
In the article there was given the survey of research results of leaf and leaf surface area potential of different origin in the conditions of Taman
This article is devoted to treatment effects of cuttings
of a grape variety called Moldova with 0.01% solution
of heteroauxin on their regenerative capacity,
depending on the light conditions. We have established
that the germination of cuttings in the dark, as well as
the treatment of heteroauxin significantly stimulate
their regenerative abilities. The length of the shoots,
regardless of the use of heteroauxin, depends on the
mode of the light produced during the germination of
cuttings. In both studies, the length of the shoots on the
end of experiment cuttings germinated in the dark, was
1,71-2,66 times more than when germinated in the
light. Cuttings rooting ability also largely depends on
the light produced in their germination. In both studies,
the rooting of cuttings started earlier and passed more
rapidly during their germination in the dark.
Processing cuttings with heteroauxin, followed by
germination in the dark, speeded up the formation of
roots even more, compared with the case where the
cuttings treated with heteroauxin germinated in the
light. In the best case rooting increased by 42,5-47,5%,
the number of roots on basal ends of cuttings in 18,3-
18,5 times, the numbers of cuttings with 3 or more
roots to 72,5-80,0%
