air temperature at different dates of sowing and preplant
seed treatment by the preparation "TMTD-plus"
containing the growth promoter called Krezatsin in its
composition. The studies were conducted in
accordance with the thematic plan of scientific
researches of the department of crop and forage
production of Stavropol State Agrarian University. The
technology of maize growing on the experimental plot
corresponds to the standard technology for this area
and culture. The sowing was performed in three stages.
The first (early) sowing period was at t = + 7 ... +8 ° C.
The second (recommended) – was at t = + 10 ... + 12 °
C. The third (later) sowing period was carried out at t
= +15 ° C. There was identified a high inverse
correlation between the average daily air temperature
and the duration of the intraphase periods of maize
propagation. Thus, at the shifting of maize sowing
dates with the second half of may on the second half of
April, the optimization of heat regime in the generative
period and rising of efficiency of use of thermal of
resources of the region. There was marked the
acceleration of development of corn seedlings when
the average daily air temperatures was up to +12 ° C

In the review article we present a comparative analysis of frost resistance of varieties of winter barley and sunflower (Helianthus annuus L.) by the results of freezing in the refrigerating chambers and by the hygroscopicity of mature grain. On the example of a number of varieties of both cultures, it is shown that the higher the frost resistance of the variety, the smaller the volume of the supernatant can be obtained by extracting the press cake with a solution containing magnesium cations. It is assumed that increased hygroscopicity of winter barley and sunflower press cake is associated with a relatively high content of so - called "water-soluble starch" - β-glucan polysaccharides in its grain. The possibility of regulation of the degree of hygroscopicity under the influence of potassium (KNO3), zinc (ZnSO4) and gibberellic acid (GA3) was studied on a number of sunflower varieties. It was shown that treatment with a solution of potassium (a concentration of 50 ppm KNO3) of sunflower plants at the stage of 4 leaves leads to a significant increase in hygroscopicity of grain and hardiness of plants, little effect was given treatment with zinc (30 ppm ZnSO4) and a lesser effect was observed when treating plants gibberellovaja acid (20 ppm). Potassium treatment significantly intensified the biosynthesis of free Proline, phenolic compounds and soluble proteins. When processing zinc significantly increased the content of carbohydrates in sunflower plants. Hygroscopicity showed a significant correlation with the content of free Proline (R2=0.621), phenolic compounds (R2=0.907), total carbohydrates (R2=0.673) and soluble proteins (R2=0.708). It is assumed that the treatment of plants with potassium and zinc plays a key role in increasing the hygroscopicity of grain. The results of comparative studies of frost resistance on the degree of survival of plants during freezing in cold rooms and the degree of hygroscopicity of mature grain showed that these two methods of assessing frost resistance give very close data. At the same time, in terms of simplicity and low economic costs, the proposed method of assessing frost resistance is many times superior to the method of direct freezing of plants
It is assumed that in the primordial state of the Universe
was missing the elements of matter, it was submitted to
electromagnetic photon field in a broad frequency band.
Photons with energy ε=1,02 born MeV electrons and
positrons, and photons with energy ε=1,87 born МeV
protons and antiprotons. The Association of protons,
electrons and essential spectrum of photons created a
sustainable hydrogen atoms and neutrons. Association
of hydrogen atoms led to the creation of hydrogen
clusters, and merging neutron – neutron creation of
clusters (pulsars). As a result, the concentration of
photons in the Universe decreased and the universe
were compressed. The gravitational interactions
between the hydrogen and neutron clusters was coming
off of a mass of matter from both. The torn mass of
hydrogen clusters were created on the planet.
Separation of the mass from neutron clusters led to the
neutron exposure of the main hydrogen clusters and
loose parts from him (future planets). The latter, being
closer to the main hydrogen accumulation, under the
influence of neutron flux were redesigned to all
elements of the periodic table. The article describes
nuclear reactions convert one chemical element to
another. After irradiation of the primary hydrogen
clusters of neutrons and the emergence of the heavy and
superheavy hydrogen, started fusion reactions with the
release of photon energy and the transition of hydrogen
clusters in Stellar condition. They began to glow. The
selection of the photon energy of the Stars led to the
increase in the concentration of photons in the
Universe, the increase of the pressure and the expansion
of the Universe, which is what happens at the present
stage of its development. Combining antiprotons,
electrons (positrons) with the required spectrum of
photons created sustainable antihydrogen and
antineutrons, and their clusters – clumps of antimatter
in the Universe
The study of agronomy plants history, its distribution
and use through image analysis and iconography have
been presented. As an object of study, the image of
wheat has been taken as the ancient culture of the
world among agricultural plants. After many years, the
illustrative series takes on a completely different
meaning, namely, it becomes an independent resource
of information. The analysis includes images of wheat
in painting, sculpture, mosaic, tapestries, murals,
botanical illustrations, stamps, porcelain and scientific
drawings. In the work, we have made an attempt to
analyze the images of wheat in the works of art in
order to search for species diversity, directions of
selection and genetic research, and also to present the
morphological characteristics of culture. The method
of analysis is a method of visual notes or sketches,
which consists in comparing and searching
information by image. The analysis is carried out on
grounds: tall wheat, multiflorous forms of wheat, nonspreading,
thickness of straw. The visual analysis of
the images of wheat in works of art by the method of
sketches made it possible to reveal the species
diversity of culture along the ear, to see the ancient
forms that were cultivated in the world before the
"green revolution". The analysis included works of art
from the 14th to the 21st century, the masters of
painting in Italy, Germany, Russia, the Netherlands,
France, the United States, and others
The article discusses the specific character of the representation of the notion “Security Architecture” presenting the concept “Construction” in Russian, German and English linguistic fields. The peculiarities of the cultural and historical development, fundamental divergences of the political systems,
levels of economic and social progress, different world -view and world interpretation of Russia, Germany, Great Britain and the USA resulted in causes of the polar appreciation of the notion “Security Architecture” from the point of view of national and international interests. The increasing tendencies of the global changes in the world politics and political line of these countries are reflected in lexical language figures and in social journalism realized in the political discourse. The undertaken trends of the lexical-semantic and comparative analysis of present lexical units and certain texts of Russian, German and Anglo-American printed mass media and research papers have revealed the different comprehension of the notion “Security Architecture” in the national linguistic cultures. It made possible to draw a conclusion on polar connotation of the notion in Russian, German and English conditioned by the specified tendencies in political, ideological and economic fields. To the opinion of the author the notion “Security Architecture” presented by the concept “Construction” because of its actualization may claim to be universal and therefore be related to the constants of culture. In this regard, the analysis of the notion “Security Architecture” as a part of the present concept is of a substantial interest. Due to results of the present research, the author resumes the peculiarities of explication of cognitive signs and the reasons influencing the transformation of the notion in Russian, German and English linguistic cultures
The authors made an analysis of biotechnology firms,
working in medicine. In terms of the current direction
of Russian economy in the process of import
substitution, the researched topic of this article has its
urgency based on understanding that to build
competitive industries in the Russian Federation it is
necessary to examine and adjust experience of leading
states with certain achievements in pharmacology.
Implementation of industry development programmes
is possible not only through the active participation by
state administration, but also through understanding of
how overseas market participants operate. Thus, the
object of research is companies of the biotechnology
industry, the subject of the research are the financial
indicators in relation to industrial value chain
strategies. The United States market data was used
because of the availability of substantial sources of
information that are easier in intelligence conduction,
and also due to the fact that the experience of the
developed market economy can serve as a model for
understanding the work of the business and its patterns
for domestic entrepreneurs and public servants. Based
on analysis made with descriptive statistics and
econometric tools the authors demonstrated the
correlation between financial performance and strategy
of the value chain
The specialties of character creating in oeuvre of L.S.Petrushevskaya are examined in the article from the position of archetypal concept of K.G.Jung. There is also an identified connection of female characters of the writer with their mythological foretype – Mother-Goddess in aspect of “Mother-Earth”
Based on the analysis of the nature of some
flowering test crosses which have been resulted in
the hybridization with purposely chosen sterile
sources (analyzers), the new self - pollinated lines
of maize have been identified according to the
content of fertility-restorer genes of ‘C’ type of
CMS. Genotype of the line RD 257 -
rf4rf4rf5rf5Ff6Rf6 (class II), genotype of the line RD
245 - rf4 rf4 Rf5 Rf5 rf6 rf6 (class III), genotype of
the line RD 274 - rf4rf4Rf5Rf5Rf6Rf6 (class V),
genotype of the line RD 231 - Rf4Rf4rf5rf5Rf6Rf6
(class VI ) genotype of the line RD 261 -
Rf4Rf4Rf5Rf5Rf6Rf6 (class VII). The identification
of the content of the alleles of fertility - restorer
genes allows forecasting the nature of flowering
hybrid progeny resulted in the hybridization with a
known genotype. We have created a catalog of self
- pollinated lines of maize according to the fertilityrestorer
genes, which consists of 18 lines, which
have been studied in all the years of research. We
have identified the lines belonging to classes I, II,
III, V, VI, VII and VIII. During the transfer of
maize hybrids on a sterile basis the lines of classes I
and VIII are those ones which have been of great
interest. The self - pollinated lines KV 204, SP 286
(class I) are the reliable fixers of «C» type of CMS.
The progeny resulted in the hybridization with any
sterile lines is characterized by complete sterility.
The new self - pollinated lines KV 498, KV 272,
KV 227, SP 357, RD 261 (class VIII) are constant
natural fertility-restorers. They are able to fully
restore fertility in hybridization with any sterile
lines and in any growing conditions
