We have described the theoretical assumptions and methodological solutions in the present review. They are innovative possibilities in the development of laboratory methods for assessing biological features of grain during the selection process
Results of three-years of examining the collection material of winter barley of different ecological-geographic origin are brought in this article. We have also allocated sources of high grain productivity, winter hardiness and precocity for further use in breeding programs
In cell biology, actinomycin D is shown to have the ability to inhibit transcription. Actinomycin D does this by binding DNA at the transcription initiation complex and preventing elongation of RNA chain by RNA polymerase. When soaking the seeds in a solution of actinomycin D, antibiotic blocks RNA synthesis and seed germination occurs at the expense of long-living RNA, available in the mature seed. In the article we present experimental data indicating that as storage seeds of winter barley are changing the action actinomycin D on the growth of coleoptiles. It is shown that actinomycin D at a concentration of 40 µg/ml in October reduced the growth, in December it was not authentically, and in February it was paradoxical amplified growing coleoptiles. We suggest the part of the actinomycin D fastened with growth inhibitor coleoptiles, whose structure changes during seed storage and increase the affinity of actinomicyn D to the inhibitors. At a concentration of 60 µg/ml actinomycin D effectively reduced of the coleoptiles growth. Suppression of seedlings roots growth was proportional to the concentration of the actinomycin D and exposure time
The article presents the data of the yield of winter barley varieties various breeding institutions in conditions of the South zone of the Krasnodar region, as well as the analysis of selected indicators of yield structure elements
The article presents an analysis of the statistical data on use of barley in the world agriculture. The dynamics of changes in acreage under crop has been studied over the past decade in the global community. The structure of indicators in barley’s area was reduced and the main regions of production have been described. As the world as some countries barley productivity was studied. The article presents the data on world production of barley for lust four years. The structure of production of the main producing counties for 2014 is presented graphically. On the basis of the material revealed, more than half of the total harvest of barley in the world has been produced by three regions: The European Union, the Russian Federation and Canada. The article presents a comparative analysis in the above productivity of barley by the world leaders in the production of this crop. A direct influence of environmental factors on final grain yield has noted. Also the issue of national economic importance of culture has been revealed. We have noted the areas of the culture use such as food, brewing industry, as well as livestock (as it is known, barley is one of the most valuable forage crops)
The article presents the results of statistical studies on
sowing area of one-year stern in agricultural production of the country and of separate regions. We have also studied the structure of the areas in the Russian Federation and presented the analysis of the areas of the one-year forage crops in the south Federal County
The article presents the data on testing of varieties of the Austrian selection in the conditions of the central zone of the Krasnodar region. Phenological observations, winter hardiness and productivity analyzed. The influences of the seeding rate on productivity of the varieties have been discussed
The article brings the results of three-year studies of the
influence of the periods of sowing on productivity of
new varieties and lines of winter barley
The article presents an overview and in-depth analysis in the area of barley grain production. The statistical data and comparative analysis of total yield of barley in the Russian Federation with respect to other cultures, widely cultivated in our country, such as sunflowers, oats and wheat has been presented. The structure of sown areas occupied by the culture of barley in the Russian Federation for the period from 1990 to 2013 has been presented graphically; we have analyzed the trend of their increases and decreases over the years. The article presents and visually shows a comparative analysis of crops like winter and spring barley. At the same time, due to a significant warming, distinct advantages of winter crops to spring crops in the cultivation of them in the southern regions of the country have been noted. The recommendations on the feasibility of increasing the cultivated area were made. Indicated by the national economic significance of culture, we show the examples of its use in industrial processing. In addition, long-term analysis of statistical data on the yield of major crops grown in the Russian Federation, such as wheat, barley, maize, millet, oats, rice, legumes, sunflower, soybean has been performed
The review examines the recent years’ data
pertaining to the interaction of plants with
nanoparticles of noble metals (gold and silver) and
with nanoparticles of magnesium as an element that
has a central role in the organization of the cellular
protein-synthesizing apparatus. Information is
presented about the effect of gold and silver
nanoparticles on plants and on possible nanoparticle
phytotoxicity. It is shown that magnesium
nanoparticles, as well as those of noble metals,
produce various effects on the growth and
productivity of plants, enabling the arsenal of
biologically active substances to be expanded.
Analysis is made of the involvement of magnesium
nanoparticles in cryobiological reaction of the
regular breakdown of plant RNA under conditions of ultra low temperatures, which is important not
only for the further developments of views of the
origin of life ob Earth but also for the purposes of
designing new markers for the analysis of the
biological peculiarities of agricultural crops on the
basis of studies of magnesium in the long-lived
RNA of their mature seeds. The presented critical
analysis of the literature data, which are often
incomplete and contradictory, suggest that a
coordinated research program is needed that would
detect correlation between particle parameters,
experimental design, and observed biological
effects
