INTERACTIONS OF GOLD, SILVER AND MAGNESIUM NANOPARTICLES WITH PLANTS

abstract 1201606047 issue 120 pp. 675 – 705 30.06.2016 ru 1094
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

PLANT HEIGHT AND LODGING RESISTANCE OF COLLECTION VARIETIES OF WINTER BARLEY

abstract 1331709015 issue 133 pp. 160 – 172 30.11.2017 ru 599
Lodging resistant is a very important factor of limitation of the yield of barley. The yield of lodged crops may be decreased up to 50%. The quality of the yield also deteriorates which negatively affects brewery characteristics. The lodging resistance of a variety is determined genetically and depends on a plant height and weather conditions during dynamic vegetation. One of the main aims of breeding of the crop for lodging resistance is the selection of short-stem varieties. However, a thorough study of the basic material and determination of its adaptability to a particular soil and climatic zone and suitability of its usage as parental forms are needed. The article covers the plant height of collection varieties of winter barley in the central zone of Krasnodar region and determines the groups of the varieties based on this trait. The dynamic of plant height formation depending on the vegetative conditions during five years is studied. The examination of lodging resistance of winter barley revealed that there are many non-lodging forms of the crop. New local varieties and lines have short and strong culms. Also, some varieties from Western Europe and the USA show its good lodging resistance under these conditions

RETROSPECTIVE ANALYSIS OF THE WINTER BARLEY VARIETIES ESTABLISHED IN THE SOUTH OF RUSSIA

abstract 1231609024 issue 123 pp. 347 – 365 30.11.2016 ru 1073
Barley (hordeum vulgare) is a valuable food and forage crop. It is cultivated in the world on an area of about 60 million hectares. A major region of barley cultivation in the Russian Federation is the Southern Federal District. The variety is one of the main factors determining the demand for crop. To use the varieties effectively we must have a complex of economically valuable traits such as hardiness, resistance to lodging, disease and pest resistance. These traits make it possible to generate the harvest high and stable from year to year. The article is devoted to the analysis of winter barley varieties, created in the south of Russia from ancient times to the present day. The main achievements of the leading Russian breeding facilities and experienced breeders of scientists set out in chronological order. The article describes the methods and principles of selection (from individual selection to mutagenesis and complex selective breeding) used to breeding the new varieties of winter barley. The most attention is given to the outstanding varieties included to the mating program today

SPECIFICITY OF TRILON B INFLUENCE ON THE GERMINATION OF SEEDS OF VARIETIES OF WINTER BARLEY

abstract 1201606048 issue 120 pp. 706 – 729 30.06.2016 ru 731
The problem of increasing resistance of winter barley to adverse conditions of winter is the most problem in the selection area of this crop. The main component of this complex trait is the frost resistance. Laboratory methods of assessment of frost resistance are important for breeding of winter barley. These methods can effectively replace more costly method of direct freezing in the freezers. Magnesium cations (Mg++) are essential components of the protein-synthesizing system of germinating seeds. Magnesium cations determine the stability and translational activity of mRNA and rRNA. Trilon B is usually used for in vitro banding of magnesium cations in area of biochemistry of the nucleic acids. It was very interesting to verify the Trilon B influence to seed germination of winter barley varieties by experiment. Experiments showed: actinomycin D – the inhibitor of RNA synthesis – didn’t show varieties specific effect to seed growth of winter barley, while Trilon B had a varieties specific impact to length coleoptiles and roots. Research was carried out on etiolated seedlings at temperatures from 22 to 28oC, and different concentrations of Trilon B - 1,6×10-3Ðœ, 2,4×10-3Ðœ and 3,2×10-3Ðœ. The roots of 3-days old seedlings were more sensitive to Trilon B influence. It is shown the varieties of Russian origin were naturally reacted to Trilon B: the higher the frost resistance of variety, the more resistant variety to the action of various concentrations of Trilon B at different temperatures. The most optimum concentration was 3,2 × 10-3Ðœ at 22-25oC. Varieties by foreign origin deviated from this pattern. It is interesting to research the genetic essence of these differences. It will be helpful for optimization of varieties differentiation conditions to create a laboratory method of estimate of frost resistance of winter barley. The new method will be most efficient compared the direct freezing method

STATISTICAL STUDY ON WORLD PRODUCTION OF BARLEY GRAIN

abstract 1061502069 issue 106 pp. 1062 – 1070 28.02.2015 ru 1336
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 STABILITY OF PERSPECTIVE VARIETIES AND LINES OF WINTER BARLEY OF KUBGAU BREEDING TO THE PATHOGEN OF DWARF RUST

abstract 1171603011 issue 117 pp. 204 – 218 31.03.2016 ru 577
Due to the wide spread of winter barley varieties with different Phytopathologic characteristics, a serious threat to the crop is dwarf rust caused by a pathogenic fungi of the Puccinia. The article presents the results of phytosanitary studies conducted in different agroclimatic zones of the North Caucasus region for the period from 2013 to 2015. Electronic maps of levels of development and distribution of dwarf rust are based on phytosanitary inspection. On the experimental field called «Kuban» as well as rust nursery of VNIIBZR we have performed an immunological evaluation of the sustainability of winter barley accessions to the pathogen of the dwarf rust on natural and artificial infectious backgrounds in the period from 2013 to 2015. The article reflects the objective characteristics of varieties and lines of winter barley with a relative stability to the North Caucasian population Puccinia hordei. The most promising varieties and lines of winter barley of the KubGAU breeding were selected during operation. These varieties and lines are highly resistant to rust and dwarf, they also have other valuable features. The article presents information on the best yield varieties and lines of winter barley as well as on gross yield and sowing area
