USING OF SSR MARKERS IN GENETIC STUDIES OF PRUNUS GENUS
DescriptionThis article discusses the actual problem of using SSR-markers in studies of the genus Prunus. We have examined the works on the most important cultures of genus, collected and analyzed contemporary literature of the subject. Data of the initial stage of Prunus SSR-based genetic diversity study in the North-Caucasian region has been described in the presented publication

THE APPLICATION OF THE BACTERIOPHAGES TO COMBAT COLIBACILLOSIS AND CAMPYLOBACTERIOSIS IN POULTRY
DescriptionThis 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- 00991 and № 16-44-230855-р_а

Description
The article presents the long-term data (2007-2015.) biometric aboveground plant parts and the estimation of the prospects of the three introduced botanical species of juniper and recommendations for their use in landscape design. We have established very promising, promising and unpromising varieties for landscaping in the conditions of the foothill zone of the Krasnodar region out of 16 varieties of juniper species: China, ordinary and rock

USE OF EPIN-EXTRA, R PREPARATION ON SEED PLANTS OF ONION
DescriptionAn important element in the technology of growing seed plants of onion is the use of physiologically active substances to protect plants from frost in early spring growing season. Damage to plants during this period affects seed production. In the experiment we used preparation called Epin-Extra R, with which the leaves of plants were treated a day before expected frost. Test results have shown high efficiency of preparation in the field and in the film unheated greenhouse. Treatment helps to balance the negative impact of low temperatures and obtain an additional seeds yield 92-95 kg / ha more compared with the control, due to the increase of seed of productivity of plants to 3.2 g

Description
The research of the territory adjacent to Novocherkassk state district power station, for the content of polycyclic aromatic hydrocarbons (on an example of benzo(a)pyrene) is presented. The benzo(a)pyrene content in soils has been determined with a method of subcritical water extraction. The content of benzo(a)pyrene in soils of the territory adjacent to Novocherkassk state district power station has been estimated. It is shown, that contents of benzo(a)pyrene excess over maximum permissible concentration in soils of five-kilometer zone around the companies

INVESTIGATION OF TRACE ELEMENT COMPOSITION OF RAW STEVIA REBAUDIANA BERTONI MATERIALS
DescriptionThe article gives an analysis of the elemental composition in raw materials of stevia. Stevia plant is able to regulate the flow of heavy metals, allowing them, on the one hand, actively oppose the excessive intake of toxic elements and on the other hand, selectively cumulate essential elements. The contents of essential elements in plant raw materials do not exceed the acceptable standards regardless of the growing conditions

Description
Residual amounts of pesticides in the coastal water of the Azov Sea were studied in the spring seasons of 2009–2011. The concentrations of the pollutants were determined and the degree of their danger for hydrobionts was assessed. The concentrations of pesticides diluted in the water of the Taganrog Bay and the eastern Azov Sea are shown to be lower than the maximum admissible concentrations set for fishery ponds

STUDYING THE GROWTH CHARACTERISTICS OF PINE GEOGRAPHICAL CULTURES IN THE CENTRAL FOREST-STEPPE
DescriptionThe results of studying the ordinary pine condition in geographical cultures of the Central forest-steppe are cited in the article. The general pattern of the ordinary pine intraspecific variability is represented. The data of origin influence on safety, efficiency, qualitative adjectives are presented. The pattern of ecotypes adaptability to new environment conditions is presented
