THE ADAPTABILITY OF VARIETIES OF WEIGELA (WEIGELA THUNB., CAPRIFOLIACEAE) IN THE CITY OF KRASNODAR
DescriptionThe 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

SOIL DEGRADATION AND THE ROLE OF FOREST BELTS IN LAND MELIORATION
DescriptionSoil degradation (erodere – eat away, lat.) - a process when pieces of rocks and soil are separated from their initial location. Then transferred and deposited in some new place. The factors of erosion are water, wind, landslides, rock particles and etc. Erosion is the process of destruction and demolition of the soil cover (or parent rocks) by flows of water or wind which causes depletion of fertile top soil layer. The destruction of this layer occurs quickly, and for its restoration thousand years are required. Reduction of soil fertility is one of the main problems that are associated with its pollution. Erosion is a natural process that occurs very slowly ever since the Earth was formed (about 45-50 billion years ago). Realistically, mountains, valleys, plains and deltas on the Earth's surface have been created by water and wind erosion as a result of their joint action over a long period of time. Geological erosion was acted at a slow pace for hundreds of years. When humans appeared it occurred to be an invasion of species which could transform their natural environment. An artificial type of erosion, which acts much faster than the natural erosion, was formed because of human

STATE OF THE RIGHT BANK OF THE CHELBAS RIVER IN CHELBASSKAYA VILLAGE IN THE KRASNODAR REGION
DescriptionThe river Chelbas – is the steppe river passing through all Chelbasskaya village of the Kanevsky area. Selting of small rivers leads to rise in level of ground waters and bogging of flood plains which become unsuitable for any use. Harmful influence can conduce coming in a reservoir of a large number of suspensions. Suspensions increase water turbidity, reduce depth of penetration of sunshine, i.e. reduce a layer in which there is a photosynthesis that conducts to decrease of primary production of a waterway and deficiency of oxygen. The increase in ground rainfall can lead to change of fauna of a benthos, a silting of spawning areas, death from suffocation of have already spawned caviar of fishes. Research of the right river bank of Chelbas in the territory of stanitsa Chelbasskaya included studying of qualitative structure of wood, shrubby and grassy vegetation of a coastal strip, visual assessment of its state and definition of the general projective covering. In the lower current of these rivers the mineralization raises to 3-5 g/l. It speaks, apparently, by that the water containing alluvial deposits in the top parts of valleys have higher filtrational properties better are washed out, than on surrounding watersheds and slopes, and also down valleys. Works on bank protection will improve a condition of a right-bank strip of river Chelbas

ISOLATION AND SELECTION OF THE NON TRANSDUCING E. COLI BACTERIOPHAGES FOR ANTI-COLIBACILLOSIS DRUGS
DescriptionThe isolation of E.coli phages from samples of natural and waste water obtained during expeditions in the different regions of Russian Federation was carried out. The obtained phages (286 isolates) were tested for their ability to lyse the pathogenic strains of E. coli – pathogenic agents of pig colibacteriosis in Krasnodar region. The study was conducted of their ability to phage transduction, the molecular-genetic characterization and biotechnological parameters of selected bacteriophages. For first experimental design of veterinary drugs was selected 5 coliphages having no ability of plasmids transduction. It has been shown that all the investigated phages are representatives of T4-type phages of family Myoviridae. The reported study was partially supported by RFBR, research projects No. 08-04-99111, 09-04-10132, 16-44- 230855

PROPERTIES OF FOREST SEED SAMARA, WITHOUT PTERYGOID APPENDAGES, LEGUMES AND WITHOUT PERICARP
DescriptionProperties of forest seeds are the basic and initial data for substantiate technology and technical means constructions, to separate the seeds from the samaras and extraction them from the legumes, and also to substantiate constructive, technological parameters and operating modes of seed-cleaning machines. So far, there are not enough full information about the technological and mechanical properties of forest seeds, this makes it difficult substantiation and developing new technologies and technical means, in particular, to separate the seeds from samaras hardwoods and extracting legumes from the leguminous trees. The article presents the results of studies of technological and mechanical properties of forest seeds with samara and without pterygoid appendages: Norway maple, ash and elm ordinary, as well as legumes: honey locust, white acacia, acacia yellow and pure seed. Were studied: weight of 1000 seeds, volume weight, mass and volume coefficients, angle of repose, the coefficient of static friction and the coefficient of dynamic friction of the various working surfaces, holding strength samaras to forest seeds and strength of legumes pods. The data obtained are used for substantiate technology and technical means constructions, to separate the seeds from the samaras and extraction them from the pericarp

PERSPECTIVES OF DEVELOPMENT OF AGROLANDSCAPES IN THE STEPPE ZONE OF EDGE
DescriptionStudies of ecosystems allow estimation of difficult processes (physical, chemical and biological), taking place in them and determine how to manage them. At the heart of the natural systems there are freely interacting populations of different taxons, productivity of their above-ground structures, details of which are quite limited, and as underground systems, the data have even less information. In the late 60s and early 70s in the XX century a lot of information appeared associated with problems of environment, its pollution, lack of energy of food resources, clean water; it determined the root cause of the reaction of the population of developed countries on the aggravation of relations between society of people and habitat. Existed for a long time the concept of the exploitation of nature, which reflected on using soils, forests, water and other sources and which showed the power of mankind and its technical power over nature. In reality, this concept was just a common strategy of aphids sucking their environment. Understanding the real situation on the different levels of consciousness of the population defined situation of practical and scientific research in the field of ecology of different directions - chemical, biological, mathematical and other sciences. Development of ecology today will evolve to meet conservation and sustainable development of the biosphere, which experiencing constant anthropogenic pressure. An important problem of agrolandscape systems is an objective assessment of their productivity. Among the issues that determine the development of agricultural systems there are the natural conditions and soil fertility, crop dynamics over the years, the duration of the growing season of individual taxons, as well as the possibility of create of mixed crops, different type of life form, ecological features, physiological diversity of biochemical characteristics. Sowings this type allow, under certain conditions, obtaining stable yields under any climate dynamics and significant reduction of soil erosion. Combined sowing that is practiced in South East Asia, particularly in China, where the main components are the soybean and corn. The usefulness of mixed crops is the stability of yields over the years and the ability to emphasize their resistance to dry weather conditions

INTRODUCTION OF RHODIOLA ROSEA L. IN THE CENTRAL YAKUTIA
DescriptionThe flora of Yakutia is rich in medicinal plants. Many of these plants are not still studied totally. The species Rhodiola (Crassulaceae) is one of the most popular family which are widely used by the local population for therapeutic purposes. Medicals use the rhizome and roots of Rhodiola rosea as a source of medicinal raw materials. This means the removal and destruction of plants. The procurement should be carried out solely on the basis of plants grown in culture because of the rarity and few natural reserves of the species. R. rosea L. passes a full cycle of the sprouts, blossoming and bearing fruits during the introduction in the conditions of Central Yakutia. The weather conditions of the year influence on the rate of development and growth processes very strong. The experiments determination of the germination of local reproductions were negative. The sprouts grow very good. In this case, it is good possibility of intense vegetative reproduction of Rhodiola. The evaluation of stability of introduction may be attributed to the kind of group stability. The great potential and adaptive capacity of R. rosea significantly enhances the possibility of growing this species under conditions of the Central Yakutia. It is recommended to improve and elaborate of protection of natural populations and unique plant communities

CHANGES IN ORDINARY CARBONATE CHERNOZEM CONDITIONS CONSIDERING MODERN HYDROMORPHISM
DescriptionThere are changes in almost all the properties of chernozems under locally overmoistening. In general, changes in the properties and conditions of chernozems under the development of local wetlands went in a particular way, regardless of the peculiarities of soil formation factors and causes waterlogging. The most noticeable change is the transformation of physical properties of soil and organic matter status. According to our research, more quickly and clearly excessive moisture causes a change in the physical properties of the soil. There are changes of the structural state, bulk density and amount of water-stable aggregates. The significant change is the transformation of soil organic matter. There is increasing of total humus content. In a group composition, the fraction of humic and fulvic acids increases the share. The humus profile is stretched. In the majority of cases in investigated soils was diagnosed secondary salinization. The periodic waterlogging of the soil also contributes to the change in the amount of soil carbonates and their distribution in the profile. Chernozems gradually lose calcium, the main structurant and humates maker. Among the most studied soil of Zernogradsky region in the cationic part of the prevailing spot goes sodium. In addition, the narrowing ratio of calcium to magnesium was observed. That is the hallmark of the aqueous extract of locally overmoistening soils
