The article presents results of studying the oenology
and the biochemistry of the Cabernet-Sauvignon
grapes in different areas of the Krasnodar region -
Taman, Anapa, Abrau-Dyurso, Gelendzhik and
Krasnodar. The yields, the mechanical composition of
the grapes, the biochemical indicators of the juice of
berries were compared. The cultivation zone affects
the yield, the average mass of the bunch, the number
and mass of berries in the bunch, the mass of the crest,
but according to the percentage of berries and crest in
the bunch, the bunch structure (ratio of mass of berries
to mass of the ridge) does not significantly differ
between growing zones. The mass of 100 berries and
100 seeds, the weight of seeds in 100 berries, the
clustering index (the ratio of pulp with juice to peel)
can differ in different places of growth, but with
insignificant coefficients of variation. The composition
of the bunch as a percentage of the total mass varies
little over the growing zones: the ridges make up 5.6-
5.7%, the skin 4.9-5.2%, the seeds 4.8-4.9%, the pulp
with the juice - 84.3-84.5%. Structural and berry
indicators varied in the range of 5.4-5.5 and 76.84,
respectively. Depending on the place of cultivation, the
yield of the grape must in laboratory conditions was
75.1-75.7%. Analysis of the structure, composition and
the structure of bunches showed that the mechanical
composition of Cabernet-Sauvignon refers to the first
group of varieties that retain their valuable
characteristics when changing the growing conditions.
When harvesting, the mass concentration of sugars was
19-19.8%, titrated acidity - 8.1-9.2 g / dm3, pH - 3.3-
3.4. Depending on the place of cultivation of the
content of organic acids in the juice of berries was:
wine - 4917-5918 mg / dm3, apple - 1926-2763, lemon
- 215-416 mg / dm3. In different places of cultivation
in% of the total amount of organic acids studied, the
content of tartaric acid varied from 61.7 to 71.4%,
apple - from 24.7 to 33.3%, lemon - from 3 to 5%.
Thus, the content of organic acids in the juice of
Cabernet-Sauvignon berries depends on the specific
growing conditions. Depending on the growing places,
the mass concentration of potassium cations is 2630-3508 mg / dm3, sodium 162-436, magnesium 171-230,
calcium 185-255 mg / dm3. However, in most cases,
as a percentage of the total cation content, there are no
differences depending on the site of growth. Thus, the
biochemical parameters of the juice of CabernetSauvignon
berries depend on the specific natural
conditions of the terrain and, according to these
parameters, the variety belongs to the second group of
varieties with less plasticity to different growing
conditions
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
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
The article discusses the use of automatic systemic-cognitive analysis (ASC-analysis), its mathematical model is a system of information theory and software tools – an intellectual system called "Eidos" for the solution of some problems of ampelography: 1) digitization of scanned images of the leaves and creation of their mathematical models; 2) the formation of mathematical models of specific leaves using the spreading of information theory; 3) the formation of models of generalized images of leaves of various sorts; 4) comparing an image of a specific leaf with a generalized image of the leaf of different varieties and finding a quantitative degree of similarity and differences between them, i.e. the identification of the varieties on the leaf; 5) quantification of the similarities and differences of the varieties, i.e. cluster-constructive analysis of generalized images of the leaves of different varieties. We propose a new approach to digitizing images of leaves, based on using the polar coordinate system, the center of gravity of the image and its external contour. Before scanning images we may use transformation to standardize the position of the still images, their sizes and rotation angle. Therefore, the results of digitization and ASC-analysis of the images might be invariant (independent) relatively to their position, size and rotation. The specific shape of the contour of the leaf is regarded as noise information on the variety, including information about the true shape of the leaf of the class (clean signal) and noise, which distort this true form, originating in a random environment. Software tools of ASC-analysis – intellectual "Eidos" system ensures noise reduction and the selection of the signal about the true shape of the leaf of each variety on the basis of a number of noisy concrete examples of the leaves of this variety. This creates a one way form of a leaf of each class, free from their concrete implementations, i.e., the "Eidos" of these images (in the sense of Plato) is a prototype or archetype (in the Jungian sense) of the images
It is well known that genetics studies the mechanisms of variation/heredity and widely uses the concept of "genetic information". While genetics considers the information as the content of the genetic code - structure of DNA and RNA included in the cell of a living organism. Genetics examines the mechanisms of recording, copying, readout of genetic information, the possibility of its modification and its influence on the characteristics and properties of the organism. In conversational and scientific language we know phrases, such as "Genes contain information about the characteristics/properties of the body." Paradoxically, we see no attempts to determine the amount of information contained in specific genes on specific characteristics or phenotypic properties of the organism. It would seem that the application of information theory in genetics is a completely natural and suggests itself. More strange that there are practically no works devoted to the application of information theory for solving problems of genetics. This article is intended, to some extent, to fill this gap on the example of calculating the amount of information in the genes of the characteristics or properties of different grape varieties. It examines the application of automated system-cognitive analysis (ASC-analysis), its mathematical model – system of information theory and software tools – intellectual system called "Eidos" for solving one of the important tasks of genetics: determine the amount of information contained in the genes on various phenotypic characteristics/properties of the grapes. To solve this problem, we perform the following steps: 1) cognitive-targeted structuring of the subject area; 2) the formalization of the subject area, i.e. development of classification and descriptive dials and graduations and training samples; 3) synthesis and verification of information model, reflecting the amount of information in the genes on the phenotypic characteristics/properties (multiparameter typing); 4) displaying the information about the genetic determination system of phenotypic characteristics/properties (SWOT analysis of Fennovoima); 5) displaying the information about the strength and direction of influence of a specific gene on phenotypic characteristics/properties (SWOT-diagrams of genes); 6) the solution to the problem of system identification phenotypic characteristics/properties by the presence of certain genes; 7) quantification of the similarities-differences of the various phenotypic characteristics/properties, upon determination system genes. A specific phenotypic property (or characteristic) is regarded as a noisy genetic text, including genetic information about the true gene property (clean signal) and the noise that distorts this information due to the random effects of the environment. The software tool of the ask-analysis which is "Eidos" intellectual system provides the noise suppression and the selection of true signal
In this article we present information on features of
microcloning in culture of in vitro of perspective for
Eurasia, pink and white-berry table genetic grades of
grapes by I. A. Kostrikin, V. N. Kraynov and V. V.
Zagorulko. Researches were conducted at an input
stage in culture of in vitro of meristems of 0,1-0,2 mm
in size. At the majority of grades and forms, we noted
good regeneration abilities in the conditions of sterile
culture. It is bound to the fact that almost all the
studied grades: Anyuta, Bogatyanovsky, the Princess
Olga, Preobrazhenie, Anniversary of Novocherkassk,
Favor are received from crossing of couple the Mascot
× Sultana-ray grape. And only grades called Libya and
Lowland which showed lower regeneration properties
at stages of proliferation and rooting of shoots are
received from crossing the couple of Flamingo ×
Arkadya and (Talisman x Tomaysky) respectively. At
the same time, the grade of Talisman, being one of the
parents of the majority of the studied grades, showed
stable results at all stages of cultivation
The article presents the results of studies of 92
indigenous varieties and 15 wild genotypes by 24
microsatellite markers. As a result a locus database about
germplasm in the collection stored at the Russian
ampelographical collection AZOSViV (Anapa Zone
Experimental Station of Viticulture and winemaking)
was created. During the research of varietal breeding
populations confirmed the validity in the production of
the cultivar of Krasnostop anapsky with obvious changes
in microsatellite sequences as a clone of famous indigenous
Don cultivar Krasnostop Zolotovskii. This clone
was selected in 1953 by prominent agrotechnologist
Zotkin Ivan Ivanovich which is propagated by the
author and his followers, and after a formal registration
submitted to state testing in 2007 in GSK RF, zoned in
the North Caucasus region (number 6) in 2014 year. Sort
-clone Krasnostop anapsky only in the Kuban today
cultivating in 35 hectares. By using molecular genetic
techniques, now clonal selection of vine grapes is reasonably
improving. Recent data collected by us in the
work process, were analyzed a comprehensive manner,
making it possible to draw conclusions about distinctness
of grape varieties. Some clones were studied by DNA
primers, based on retrotransposon sequences
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
Numerous studies have found a different quality of the
buds along the length of the fruit arms, which expressed
various degrees establishing embryonic inflorescences in
the central buds. It is revealed that many of the grapes
have more fruit-bearing eyes formed on average (4-6
knots) and upper (7 to 10 knots) levels of fruit escape,
compared to the lower (1-3 nodes) layer. In connection
with the different quality of the buds along the length of
fruit vines should be used and different ways of cutting
them. It is necessary to consider the biological
characteristics of varieties, ways of doing and shaping
the bushes, the weather conditions of the area during the
growing season and relative calm. To receive annually a
stable high yield of grapes, we must first set the optimal
length of pruning fruit shoots and optimal load on the
Bush healthy eyes. This requires for each class on the
eve of trimming bushes to carry out the analysis of the
wintering holes along the length of the fruit shoots and
to identify the embryonic fruitfulness of Central buds,
i.e. to carry out the prediction of grape yield next year.
The article presents data on the formation of the
embryonic fruitfulness of Central buds of wintering buds
at the Taman group of grapes – Arcadia, Viorica,
Hibernal, Cabernet Sauvignon, Merlot, Moldova, Pinot
white, Riesling, Saperavi, Traminer pink, Tsimlyansky
black, Chardonnay. Found higher rates of embryonic
fruitfulness of Central buds buds in the studied grape
varieties - Chardonnay, Riesling, Viorica, Hibernal,
Merlot, Moldova, where the coefficients of fruiting
ranged from 1.40 m from Riesling to 1.69 from Merlot;
factor productivity of 1.58 from the Chardonnay to 1.77
from Merlo. The high percentage of fruitful buds from
80,8 from Cabernet Sauvignon to 95.6 in the cultivars
Merlot and Chardonnay. A higher percentage of eyes
with 2 embryonic buds in the cultivars Merlot and
Viorica who have this indicator amounted to, respectively: 75,6 and 70.6%. Forecasting a crop of
grapes next year to trim the bushes on the proposed
method will provide a full crop of grapes
The article presents the results of the study of yield, mechanical and biochemical composition of Merlot grape vine variety and its two clones in the conditions of Taman and Anapa subzone of the Krasnodar region. Clones differ from the maternal variety by the large number of berries in the bunch, the mass of the berry, the average mass of the bunch and the yield. Maternal variety and its clones are characterized by very close percentages of berries and combs in the bunch and by indicators of the structure, composition and structure of the bunch. By the yield of juice percentage, in different growth areas clones showed the same results as the original variety. According to the content of glucose, fructose, organic acids (wine, apple, citric, succinic), potassium, sodium, magnesium and calcium cations in the juice of berries, there is no reliable differences between the original variety and its clones. The content of dry substances, sugars, titrated acids, and the sugar-acid coefficient depended on the yield, but in general, they were favorable for the production of wine materials and juices. Merlo phanagoriiskii and Merloc are ecologically plastic and belong to the first group of varieties that retain their valuable characteristics in different areas of growth
