The article gives the results of the study of the texture
of the grapes and biochemical characteristics of red
wine grape varieties of Cabernet Sauvignon, Cabernet
Franc, Merlot, Sapeari, Tsimladar, Pinot Noir for the
production of juice of direct extraction and blending.
The studied varieties in terms of the structure of the
cluster may be divided into three groups of blackpinene
(21.1), Cabernet Franc and Tsimladar (18.7 -
17.5), Cabernet Sauvignon, Merlot, Saperavi (16.5 -
16.8) , and bunches of addition in terms of two groups
- Tsimladar (17.6), Cabernet - Sauvignon and other
(15.6 - 16.4). The structural component of grapes varieties
ranged from 5.2 to 5.9, berry index - from 62.1 to
83.4, the output of the wort from 74.2 to 76.3%. The
content of sugars and acids in the berries of all varieties
is favorable for the production of beverages. The
largest Tartaric acid content was found in the juice of
the varieties of Cabernet Sauvignon, Pinot Black,
malic acid - in the juice of varieties Saperavi, Merlot,
Tsimladar, citric acid - in the juice Tsimladar varieties,
Cabernet Sauvignon, Saperavi. The ratio of tartaric
acid to the content of the apple juice Cabernet Sauvignon
was 2.9: 1, Cabernet Franc 2.6: 1, Pinot Black
2.5: 1, Merlot and Tsimladar 1.6: 1, 1.1 Sapevari: 1.
According to the content of potassium cations, sodium,
magnesium and calcium there were chosen three varieties
of Cabernet Sauvignon and Cabernet Franc. The
lowest content of potassium and magnesium cations
was in the variety of Tsimladar, Sodium – in the varieties
Merlot and Saperavi, calcium – in Saperavi. Excellent
tasting commended for juices was given to
Cabernet Sauvignon, Saperavi, Tsimladar, good – to
Cabernet Franc, Merlot, Pinot black. Best blending
juice obtained by mixing the juice of the grape of the
varieties of Cabernet Sauvignon and Pinot black
70:30, Saperavi and Pinot black 50:50. From the
grapes of produced varieties, we can produce juice and varietal by name ampelographic variety and blended to
extend the range
Differentiation has been conducted and valuation of the collection of lavender angustifolia and Lavandin according to the content of linalyl acetate, biometrics is shown, and correlations of economically valuable indicators in the cluster analysis are identified
Step by step results of many year researches of clonal selection of grape varieties: Clairette white, Saperavi, Sauvignon white and Chardonnay, growing in the Ltd company “ Pobeda” of Temryk district of Krasnodar region are cited in the article. Highly productive
proto clones were selected. Clairette white
is the best one as a variety from them and it was
given to the state experiment under the name
Clairette temryk.
In the article we have studied biological and morphological features of perspective varieties of apple-trees of different ecological and geographical origins. Taking into account the requirements of intensive gardening we have defined biometrics, water regime, allowed to estimate the variety and determine its ecological plasticity.
We have allocated apple-tree varieties of native selection such as Krasna Darya, Kuban scarlet, Peach, Renet Kuban and Pamyat Easulu; introduced varieties: Enterprise, Fuji, Red Chief, Golden Bee for sortment renewal and creation of intensive plantations of apple-trees in the Chechen Republic
On the basis of studying of collection of sorghum, the samples with important signs and properties for use in selection are marked out. Sterility fixers are defined as a result of studying of the samples on CMS, and sterile lines with the high combined ability are created
This article presents the results of the chickpea effect in feeding young and adult laying hens of "Hajseks brown" cross on their productivity and nutrient digestibility of feed. Studies have been conducted on the JSC "Agro-firm Vostok" in Nikolayevsky district of the Volgograd region. Complete or partial replacement of sunflower oil cake by chickpeas as part of feed for the experimental pullet hens improves nutrient digestibility coefficients compared with the control pullet group. The balance of nitrogen was positive in all groups, the use of nitrogen taken from guinea pullets was higher than in the control group at 0, 27-0,74%. Use of chickpea in the composition of feed for laying hens increases the digestibility coefficients of nutrients: dry matter - to 1,17-3,25%, organic matter - to 1,62-3,37% crude protein - to 0,45-1, 77%, crude fiber - to 0,72-1,05%; crude fat - to 0,35-1,55%, compared with chickens, hens in the control group. The use of nitrogen from the digested was1,37-2,13% higher in the experimental groups compared to analogs of the control group. The use of calcium and phosphorus for the formation of eggs was also higher in the experimental groups
This article presents the results of the chick peas use instead of sunflower cake, in feeding young and adult livestock hens-layers of the cross "Hajseks brown". The researches were carried out in the JSC "Agrofirm Vostok" of the Nikolayevskiy district in the Volgograd region. The sunflower cake replacement with legumes - chickpeas as the part of the experimental animal fodder for young and adult livestock hens-layers had a positive influence on productivity, physiological state of the birds, product quality and economic performance. Chick peas’ use in young hens feeding improves live weight at 1.03-4.68%, egg production in 0.99-4.7%, the average weight in 0.99-3.75% and eggs quality indicators. Morphological and biochemical indices in experimental young hens and laying hens in all the groups were within the physiological range, indicating normally occurring redox processes in the body of a bird. However, the chick peas’ application in fodder for experimental young hens and laying hens contributed to the increase of total protein, calcium, phosphorus content in serum compared with counterparts in the control group that received sunflower cake. As the researches result, the economic effect in the experimental groups was 833.01-3821.87 rubles
Tasting and smoking properties of tobacco products
depend on chemical composition of dried tobacco. The
most important are nicotine, carbohydrates, and
proteins. Their content is controlled when new sorts
are bred. In the article data on chemical composition
and their analysis for some hybrids, new and zoned
sorts are presented. Most of studied samples had
medium nicotine content in dried tobacco. Hybrid of
Jubileiniy noviy 142 and Ostrolist 46, sorts: Trapezond
159, 359, 115 and Ostrolist 46 were characterized as
low nicotine tobaccos. Jubileiniy (standard) and
Oktiabrskii were characterized as high nicotine
tobaccos. This indicator depends on rain quantity
during vegetation period. During drought seasons this
indicator is higher. Total soluble carbohydrates content
affects smoke taste. The more water soluble
carbohydrates content the better smoking properties
tobacco has. Unlike nicotine, carbohydrates content
when rainy season increases. Best results were for
Krupnolistniy 9M and Oktiabrskii. Proteins have
negative effect on smoke taste as it becomes bitter and
with smell of burned feathers. Most of studied hybrids
have quite high protein content. For cured tobacco
quality assessment, not total contents of proteins and
carbohydrates are important but their ratio
(carbohydrates/proteins) called Shmuk ratio. Best
results were for Krupnolistniy 9M and Oktiabrskii
In article the review of results of studying plant growth and development of maize, as well as features of the formation productivity of mid-season hybrid of corn Valentin depending on the variant of primary tillage (in common Harnes with Luvaram and Titus with Harmony) under conditions of sufficient moisture zone of the Central Ciscaucasia is given.
Development of confectionery sunflower openpollinated
varieties (OP-varieties) is a prospect
direction in sunflower breeding. High price level
for confectionery sunflower seeds pushes forward
the breeding program. Contrary, it is necessary to
offer product, meeting consumer’s expectation for
large seeds, good dehulling rate, proper oil and
husk content. The aim of our work is to study
morphometric peculiarities of seed structure for
sunflower OP-varieties of different types – oil and
confectionery, and to identify the best samples for
using in the breeding program as an initial material.
The study was done at All-Russia Oil Crops
Research Institute (VNIIMK) named by V.S.
Pustovoit (Krasnodar) in 2014 and 2015. Seeds of
6 OP sunflower varieties of VNIIMK breeding
were used as a material (confectionery type –
Dzhinn, SPK, Lakomka, Oreshek, Borodinskiy and
oil-type – Muster). OP-varieties were sown by
randomized blocks with 3 replications. Every plot
had 4 rows. It was shown that seeds of
confectionery sunflower OP-varieties had higher
values of main traits (length, width and thickness)
in comparison with oil-type sunflower. Seed traits
analyses allowed identifying the best confectionery
samples (Dzhinn and Oreshek) for future breeding
