The detailed morphological description of interspecific tomato F1 hybrids is represented in the article. The positive heterosis in regard to sire component was noticed in accordance with the following characteristics: fruit size, leaf size and stem length. It was established that the inclusion of tomato of Lycopersicon cheesmanii typicus genus into selection enables the obtaining of new species at the expense of increasing the range of genetic variability
The heterosis and inheritance coefficient research results among the first and the second generation hybrids which have been got from the linear and synthetic varieties of winter soft crossing are discussed in this article
Plant growing successes influence the effectiveness not only the branch in itself, but the other branches of agriculture, economics of agricultural enterprises in whole as well. In article the method of calculation of sufficient balance soil is considered.
The influence of peach-tree stocks on growth and development of different varieties in the conditions of Krymsk ESS (Krymsk) was studied. There were assessed the different parameters of growth and development of fruit trees. The most effective combinations of this culture were selected by the complex of economic signs
The article presents results of the six-year study of the
effect of stocks Riparia × Rupestris 101-14 and Berlandieri
× Riparia Kober 5BB on yield, quality of
grapes and Aligote wine in the central zone of the
Krasnodar region. Effect of stock on scion strongly
depends on the annual weather conditions. In a given
year, there is a stock better adapted to the weather
conditions. Stocks of Riparia × Rupestris 101-14 increase
winter hardiness, and the stock Berlandieri ×
Riparia Kober 5BB - drought-resistant varieties of
Aligote. On average, during six years the stock has not
been resulted in significant differences between the
percentages of developed into shoots buds and fertile
shoots shown in the coefficients of fruiting and fruitbearing
shoots of Aligote. Among all the influencing
factors, the degree of influence of stocks on the percentage
of buds have evolved to 16,4 %, by the percentage
of productive shoots 19,8 %, a factor of the
fruiting shoots and fruitfulness of 3,9 % and 2,7 %,
respectively. Some differences in forming of generative
organs of wintering buds along the fruiting twig
under the influence of stocks do not lead to the significant
difference in biological terms of fruiting varieties
in the whole piece. On average, six years of significant
differences in the influence of rootstocks on the number
of berries in bunches, hundred berries weight, an
average weight of bunches and yield is not defined -
the degree of influence of stocks on mentioned indicators
is 0,1-9,7 %. A significant impact of stocks on the
dynamics of sugar accumulation in berries has not
been discovered. The degree of influence of stocks
onto the final sugar content and acidity of berries is
2.9 and 1.0%, respectively. The wine produced from
Aligote berries on a stock Riparia × Rupestris 101-14
has the better tasting score than on the stock Berlandieri
× Riparia Kober 5BB (7.9 and 7.8 points, respect
vely). The main influence on fruiting of the variety
Aligote was provided by the conditions of the current
and previous vegetation. Within the conditions of the
central zone of the Krasnodar region the cultivating of
the variety of Aligote is reasonable for both studied
stocks
Improving the quality of Russian cognac is of great
national importance. It should be noted that about
80% of Russian foreign brandies made from aged
cognac distillates. To obtain high-quality products
necessary technical-chemical control of production
starting from the vine and the conditions of its
growth. For a comprehensive evaluation of the
totality of important factors: climate, relief, soil and
variety. It is important to add that this grading must
be accompanied by the release of environmental
macro zones with viticulture specialization. In this
regard, there has been conducted a soil-cartographic
survey of lands of ACE "Fanagoria" in the Temryuk
district of the Krasnodar region. Evaluation took
place in view of all 4 factors, notably the soil factor;
and the content of lime in the soil and the degree of
salinity of soils. Soil analyzes were carried out in
FGBNU Anapa ZOSViV SKZNIISiV using the latest
equipment generally accepted methods for
determining indicators of soil characteristics. The
purpose of the research - to give a detailed description
of the survey area, as well as highlight the boundaries
of environmental macro zones for the cultivation of
grapes brandy. During the research, it was found that
for the selection and evaluation of raw material zones
for brandy production we must take into account soil
and climatic optimum performance to get quality
brandy raw materials
The article gives an account results of comparetic evaluate of same probiotics on intestinal biocenosis development of suckling piglets. It is establish, that investigated preparates enlarge the concentration of lacto- and biphidobacterium, and reduce the quantity of Escherichia coli group bacterium
The influence of unfavorable weather factors on the vital activity of fruit-trees was shown. Peculiarities of apple-tree generative development in the connection with temperature abnormalities have been studied
The results of studying of influence of ways of sowing sorghum hybrids have shown that with increase in width of row-spacing, the crop of green weight and hay decreases, the high-quality crop of green weight is formed in the exit beginning in a tube
There were cited the results of researches for 2010-2012 obtained in the stationary experiment of the chair of general and irrigated land management of Kuban State Agrarian University on the study of influence of the system of main soil processing under soya beans on the dynamics of main agrophysical indexes of leached black soil: on density of composition, solidity, general porosity, coefficient of structural properties in the article. There was stated that in the beginning of vegetation on the background of direct sowing of soya beans, the soil layer in 0-30 cm was characterized by values of density and solidity and in the result of it we observed the weak development of the root system. The worsening of air regime led to the decrease of symbiotic nitrogen fixation, it negatively affected on the growth and development of a cultivar. Agrophysical indexes brought nearer to optimal on variants with disposal tip on 20-22 cm and disk-shaped hulling on 8-10 cm. The worsening of investigated agrophysical soil indexes has been happened since the phase of florescence – soya bean formation till the harvesting. But the variant with disposal tip where we observed the high content of agronomically valuable fraction at the coefficient of structural property 2,42 was the closest to optimal ones. The minimization of soil treatment and especially the denial from its implementation significantly made worse the main agrophysical indexes of soil on variants with direct sowing to critical values for soya beans
