This work considers the needs and methods of phage
therapy of two bacterial infections in poultry. The
review examines the use of bacteriophages, from the
moment of their discovery to the present day. We
discuss the relevance of such diseases as
compilobacteriosis and colibacteriosis transmitted
from birds to humans, we show how to use
bacteriophages and their efficacy in models of adult
birds and chickens, including information provided on
the pilot study of phage therapy at a poultry farm. The
reported study was partially supported by RFBR,
research projects No. 16-44-230855 and No. 13-04-

Sunflower is one of the most important oilseed
crops, which are of great economic importance in
Russia and in the world. It is very adaptive crop
in terms of climatic conditions range, for that
reason it is cultivated on a vast territory of the
Russian Federation in various weather conditions.
Sunflower oil has high nutritional and taste
qualities, it is used numerously in food and is
applied in various fields of food industry. The
biologically active linoleic acid, phosphatides and
fat-soluble vitamins A, D, E and K, which are of
great nutritional value to humans, are contained in
the oil. According to its calorific capacity,
sunflower oil is on the first place among
vegetable oils. Due to biological characteristics of
sunflower, the Krasnodar region is the most
favorable region of the Russian Federation for
obtaining high and stable yields of this crop.
However, here the drought is observed during the
summer period and it affects adversely the
productivity and quality of sunflower seeds. The
increasing of resistance to unfavorable weather conditions is possible only based on detailed
study of physiological features of productivity
formation and seeds quality that is highly
important task in view of the current geopolitical
situation in Russia. One way of solving this issue
is the appliance of the growth regulators,
possessing anti-stress activity that improve the
quality of sowing seeds and increase the
productivity and plant resistance to stressful
environmental factors. These drugs include
growth regulator called Furolan, which was
created in KubGTU and is certified for use in
Russia. It is not toxic and is used in nano-dozes,
there is no its residual quantities in the products
and environment. Furolan has a positive effect on
physiological and biochemical processes,
improves the productivity of plants, their
resistance to unfavorable growing conditions by
increasing the resistance to dehydration as well as
to the risk of fungal diseases
In recent years, there is an increasing in crop losses from pests and diseases of plants worldwide. The use of different pesticides in intensive cultivation technologies of winter wheat can not resist it. Pathogenic microorganisms acquire resistance to drugs used and become more aggressive. This creates a lot of environmental problems. Plants are almost always under environmental stress. In this state, they are immunodeficient. However, it is impossible to reject pesticides completely. But pesticides are not able to replace the immune system of the plant, and in some cases are suppressing it. The article provides an overview of commonly used exogenous elicitors. We discuss the most important results of the joint use of the composition of preparations of eliciting action which are furolan and methionine. The present level of development of science has led to the emergence of new methods of plant protection, which is based on increasing the capacity of the immune plants, rather than the destruction of pathogens, as in the case of the use of pesticides. The yield increase by the use of biogenic elicitors as immunizers from 10 to 30% depending on the year, the varieties of plants and especially on infectious pathogens. The elicitors are used for soil treatment, seed soaking and plants, spraying the plants during the vegetation
The most important results of applying the composition of the matter which has antidote functions furolan and methionin against the herbiside 2,4-D are reviewed in this article
The success of the introduction of plants depends on their vitality and adaptation to new existence conditions. Different adaptability of plants depends not only on the species, but also on their individual properties. The article studies the characteristics of adaptation of the perspective ornamental shrubs - Weigela, Caprifoliaceae. We have shown the variety’s morphological features, the growth and development of varieties of Weigela that have been taken during the research in the experimental Garden Center (NСRRIH&V). There is an estimation of growth rate and its dependence on the structure of different varieties of Weigela’s crown. We have examined the features of the formation of leaves: we have defined the indicators such as the number, length and leaf area; biomass, dry weight; productivity of leaves. We have estimated Weigela leaves photosynthetic activity in the introduction’s region. We have determined the number of photosynthetic pigments in the studied cultivars of Weigela’s leaves. We have found out that Weigela’s leaves pigments’ synthesis largely depends on their natural color, quality and the vegetation phase. These studies allow us to conclude that all the studied varieties of Weigela can be characterized by a high degree of adaptation and deserve widespread in Krasnodar gardens and parks due to the high decorative flowering period
The influence of exogenous form of heavy metals intake on their transformation in the soil is determined during the model experiment. Distinctions in quantity of extracted mobile compounds of heavy metals in the soil depending on a form of addition various connections of Cu and Zn are established. The smallest mobility of Cu and Zn at addition of heavy metal oxides is observed. It is established that Cu accumulates mainly in the fraction connected with organic matter, Zn accumulates in residual fraction and in the fraction connected with ferric oxide and manganese oxide by consecutive fractionation technique
Distribution peculiarities of planted Pine and Fir species (I and II age classes) in different sites of Mari high plains in accordance with their relative density and share of participation of target tree-species are described in this article. Based on the obtained
data, some actions for enhancement of ecological and
resource potential of the species are elaborated
A new science – genetics was born in the first decade of XX century. The part of G. Mendel as a founder of this science is showed here. Also here are scrutinized tasks of scientists - biologist, who assist to the making and progress of genetics
The analyze of the genetic relationship or diversity between clones was made by using the microsatellites in the groups with black berries: Cabernet-Sauvignon and Merlot, and with white berries: Riesling and Pinot. These results become the rationale for the new technology of clone selection, breeding and making registration of these clones of four above-named varieties groups in the varieties-clones for state research: Cabernek, Cabernet Fanogoriisky, Merlok, Pinot white, Rieslinalk, Riesling Anapa and Riesling Fanogoriisky. These varieties-clones are accepted by State commission of Russia, they will enrich the viticulture assortment of Anapa-Tamanskay zone of Kuban, therefore Russia
The article shows the result of the research of algaflora in reservoirs of the Nakhchivan Autonomous Republic of Azerbaijan; it is characterized by high species diversity of algae, it is represented by 135 species, varieties and forms of the two departments. Algoflora basis were 71 species of blue-green and 64 green algae. Among the blue-green algae most personable family is Oscillatoriaceae Kirchn, Microcystidaceae Elenkin and Merismopediaceae Elenk. We have identified the three highest in this kind of algae flora : Oscillatoria Vaucher Ex Gomont, Microcystis Kütz, Merismopedia Meyen. Also, we have identified the three largest in the flora of the Green Algae: Cosmarium Corda. We have found 35 species of Desmidiales, belonging to 8 genera. Ecological and geographical analysis of the flora of algae ponds in the Nakhchivan AR showed the prevalence of plankton, cosmopolitan, mezogalobnyh indifferentnıx, oligogalobnyh, and alkaliphilic
