STABILITY EVALUATION OF SOUTHERN RUSSIA SOILS TO CHEMICAL POLLUTION
DescriptionWe propose a method of biodiagnostics of soil resistance to chemical pollution and its regulation on the degree of violation of the ecological functions of soil based on the definition of the integral indicator of biological state (IIBS) of the soil. The comparative assessment of the stability of the major soils of the south Russian to chemical pollution are considered in this article
-
Description
The article gives an assessment of resistance of the brown typical soil of the Utrish national reserve to pollution with heavy metals (Cr, Cu, Ni, Pb) and oil on biological indicators
-
Description
The assessment results of urban environmental conditions on the basis of accumulation of heavy metals in the soil and vegetation are presented. The questions about the ability of different plants to accumulate heavy metals in the lives are discussed as well

ASESSMENT OF STREET PLANTINGS ON THE EXAMPLE OF SOCHI CENTRAL REGION
DescriptionThe article deals with the topical issues of ornamental woody plants used in street landscaping of Sochi Central district. It presents the quantitative composition of these species, numbering 12181 specimens. With the scale, modified for the regional conditions, we carried out an analysis of the studied plantations and their state, which revealed that weakened plants were predominant - 72.48%. Healthy plants make up over 20%. The lowest number of the specimen was recorded among the dead plants (0,26%). The analysis was carried out for all species according to the state categories. For instance, structure-forming species selected for further studies, were analyzed this way, including a large part of plants that belong to the second category of state (89,04%). Healthy plants are less than 8% from the total number of dominant species. The number of dead plants makes up 0,35%

STATE EVALUATION OF WOODY PLANTS IN ROSTOV-ON-DON
DescriptionThere has been conducted the analysis of woody plants quantity in various types of stands in Rostov-on-Don, as well as the evaluation of their state and the rate of environmental resistance destabilization. It has been ascertained that the stands of almost all of the urban gardening objects are in a salvaged condition. There have been elaborated recommendations for enhancement of the stands inspected

ASSESSMENT OF THE BREEDING POTENTIAL OF PLUS SCOTCH PINE TREE CLONES
DescriptionThe purpose of the article is an examination of plus trees clones based on growth study in the seed orchard. The studied clones differ with the characteristics of growth. The perspective clones were selected by using an integrated examination

Description
In the article, we made an estimation of pine cultures’ (Pinus silvestris L.) sanitary condition in the Savalsky Forestry area of the Voronezh region. The obtained results show their considerable weakness, passing to the drying phase because of pine fungus

Description
The results of study of production process of winter wheat amid of changing of agro ecological conditions such as seeding time, level of initial fertility, fertilizer system and variety throughout 3 year-research are shown in the article. Five hypotethetical systems are pointed out with the help of factorial analysis. Detached varieties and research years are pointed out in terms of their factorial influence

Description
Professional apple gardening is bound to particular risks, of which is essential losses of a harvest because of diseases. An apple scab, the caused Venturia inaequalis (Cooke) G. Winter, brings the greatest loss. The main approach in monitoring of a scab of an apple-tree is creation of grades, steady against pathogen. In the present work we have carried out phytopathology testing of generations of the seedlings received from the free pollination of six forms of a crab of Malus orientalis from a collection MOS VIR (Maykop) characterized by a relative resistance to the apple scab in 2-3 classes of damage by long-term data. For infection we used inoculum, consisting both of natural population of a scab, and of strains of pathogen of various cultivars and geographical origin. When carrying out padding infection increase in force of an infectious background that can be bound to selection of the plants of biotypes of a fungus that are most adapted for genotypes was noted. It is recommended for precise elimination of unstable plants at selection at early stages of an ontogenesis to carry out more than one serial infection during the season. By results of the phytopathological testing, we highlighted three Malus orientalis forms from the six studied No. 17982, 17985 and 3080 the most perspective stability genes for an introgressiya in a cultural gene pool of an apple tree
