There are determined: population area, quantity, density, age structure of cenopopulations, seeds productivity, limiting factors.

Communication quantitative chromosomal abnormalities of spermatozoa and preimplantation embryos Modern genetic diagnosis allows to establish chromosomal nondisjunction not only in postnatal and prenatal periods, but also in germ cells and early embryos. Thus, the most common nondisjunction in sperm are 18 and sex chromosomes. The most common aneuploidy in preimplantation embryos are chromosomes 21 and 18. Win abnormal embryos was 65,2 %, which indicates that the most effective elimination of nonviable embryos in early preimplantation stage.

Characteristics of regenerative processes in the reproductive system of cows in disadvantaged on viral leukemia farms Reproduction of the herd at the epizootic troubles is a challenge for many farms. Special therapeutic approach to gynecological pathology is required for detection of viral bovine leukemia.

Information Technology Education in the Soil Sciences Stroganova M. N. In article approaches to creation of informatization infrastructure of education in soil sciences and feature of the organization of educational process at the present stage are considered. This application of electronic textbooks, network means, including Internet, test quality control of knowledge. Positive and negative lines of educational process in Bologna Process are considered. Examples of equipment and ways of teaching of a soil cover of the world and structure of a soil cover in connection with new requirements are described.

Effects of Combined Lead Contamonation and Alternating Magnetic Field on the Number of Sadny Soil Microorganisms Mazanko M.S. Kolesnikov S.I. Denisova T.V. Studied the effect of lead contamination, an alternating magnetic field, their combination on such groups of soil microorganisms, as ammonifying, amylolytic, nitrogen-fixing bacteria, and micromycetes. Pollution had a significant and different effect on the number of soil microorganisms. The nature and extent of this effect varied depending on the level of impact of each factor, and they were not linear.

Biogeosistem’s Techniques — Epistemological Foundation of Ecosystem’s Maintenance Kalinichenko V. P. The basement of global of biosphere dynamics and the long-term principles of geographical sphere protection and ecosystem’s management are proposed. An epistemological base of land use is the synthesis of long-term sustainable biogeosystems with reliably predictable properties and starting conditions of long-term operation of biogeosystem for a period of 30–50 years. The increase in biological production of the Earth is possible by creating a long-term soil conditions for root system of plants development, long-term stability and productivity of biogeosystem. The radically new subsurface pulse continuous-discrete paradigm of irrigation is revealed. The biogeosystem’s technique concept will provide an opportunity to synthesize in Russia the diversified innovative precedent of next high-technological structure of the current civilization of Earth. The theoretical foundations and application-oriented means to solve a problem of steady consistent management of biogeosystem and create in the soils the disperse systems of new quality, having changed a parity of processes of sedimentation, pedogenesis, lithogenegis for high efficiency of biologically active phase of soil in biosphere and to solve a problem of recreational biogeosystem’s technique are developed.

Number and Mean Frequency of Species on Sites of Natural and Synanthropic Subalpine Plant Communities of West Caucassus Akatov V. V., Akatova T. V., Chefranov S. G. For detecting density compensation effect in subalpine plant communities of West Caucasus the relationship between number and mean frequency of species in plots 15–16 m2 were analyzed, using a computer simulation models. The results demonstrated that 1) communities with low species richness can be characterized by, as low, so and high mean frequency of species; 2) relatively high mean frequency of species exist mainly in isolated plant communities; 3) the anthropogenic transformation of natural subalpine plant communities in grazed-over area has not caused broad spreading the density compensation effect.

Norms for Arsenic’s Contamination of Soil Bezuglova O. S., Okolelova A. A. In our research we identify inaccuracy in assessment of low-degree arsenic’s contamination based on two background values to MPC, because the MPC is calculated in terms of exceeding background values higher on 2 mg/kg. We evaluate the low-degree arsenic’s contamination of soils as the difference between background values and MPC. Another informative assessment of arsenic’s accumulation in soils includes analysis of ratio of its concentration to the regional background value. In case if the regional background value is unknown, the assessment employs the ratio of arsenic’s concentration to Clark (CC). However, CC doesn’t have the classification scale. That fact reduces its benefits as useful assessment tool of soil contamination’s degree. In our article we devise CC’s classification scale that works for the assessment purposes.

Sunflower Chlorophyll Mutations Induced by N-Nitrosomethylurea and Character of Its Inheritance I. Variegated Mutants Usatov A.V. , Kolokolova N.S., Rogkova O.K., Usatova O.A., Chesnokova N.A., Fedorova M.A., Plotnikov v. G. Variegated mutants of the sunflower chlorophyll mutant collection of Southern federal university were studied. Its uniqueness consists in the fact that it was worked out on the base of one inbred line. Secondly, only one mutagen (N-nitrosomethylurea) was used for mutation inductions. Variegated mutants are characterized by leaves having white, yellow and yellow-green sectors of the various sizes and forms. Chlorophyll deficient sectors may be caused by some reasons in green plants. However, long-term researches of induced variegated mutants showed that they met the classic criteria of plastid inheritance. They are characterized by permanent somatic segregation, one-parental maternal inheritance of mutant character, defects of plastid structure and functions, presence of heteroplastid cells on the borderline between normal and mutant tissues.

170 years since the birth of V.V. Dokuchaev Bezuglova Olga Stepanovna Abstract: March 1, 2016 marks 170 years since the birth of  V.V. Dokuchaev – an outstanding scientist, naturalist, founder of soil science. His views, theoretical and practical research influenced the development of a number of related disciplines, as well as the later appearance of such sciences as the doctrine of the biosphere and biogeochemistry.   Dokuchaev's ideas to restore the fertility of chernozem  steppes, which were implemented, have slowered the rapid degradation of the soil, but the situation remains difficult. In this regard, one of the urgent tasks of modern soil science is to increase public awareness of the importance of soils for food security and the implementation of essential ecosystem functions.

It is established that this cellular interaction in vitro is implemented in the form of three different types, the intensity of which is related to the temperature parameters of the joint incubation of these cells.

Special features of highly technological processing of the tomatoes  In the food branches of the industry of many countries the tomatoes are considered as the most popular culture because of the valuable nourishing and dietetic qualities, the wide variety of types, high responsiveness to the methods of cultivation used. However, the state of technology and equipment for processing of tomato raw material existing at present requires further development and improvement.  Canning industry is the branch forming the budget of the republic of Daghestan. To 30  % the financial means of republic it comes from that processing, including from canning industry. However, according to the quality indicators and using the methods of packing the canning production, manufactured in the republic thus far cannot compete with the analogous production on the international market. In many respects the low competitive ability of domestic tomato products determines the irrational relationship between price and quality of the manufactured articles. To increase the quality of canning output and to reduce its prime cost is possible due to the thorough selection of the types of tomatoes and use of highly technological production processes. In the scientific arsenal of the technologists of  Daghestan State Technical University and Kuban State University of Technology has already been located high technologies and pour on the mechanisms of action on the qualitative composition of the tomato raw material of multi-frequency electromagnetic and ultrasonic. By the large potential of highly technological working of raw material possess the methods of the preparative separation of the components of raw material the liquified and compressed gases. New technological methods make it possible to produce production without the preservatives, the fillers, the chemical, undesirable aromatic substances and other additives. In this work we propose effective means of the solution of this problem in the use of physical, physical chemistry and chemical methods of action on the tomato raw material, semifinished products, auxiliary materials and finished production. They include the electromagnetic field of low and superhigh frequencies, ultrasound, the SO2- working, utilized in other branches industries.

SPOROBOLUS CRYPTANDRUS (TORR.) A. GRAY (GRAMINEAE) – INVASIVE SPECIES OF FLORA IN THE ROSTOV REGION O.N. Demina, L.L. Rogal, S.R. Mayorov   In the Rostov region (Russia), in the sand in the river valleys of the Seversky Donets, Derkul and Kalitva it was discovered Sporobolus cryptandrus (Torr) A. Gray. – North American adventive species. In recent years, recorded an increase in its population, which is related to the increase of anthropogenic load, including the resumption of active use of these territories as the grazed areas. At the same time, the fight against the settling of alien species that may subsequently become dangerous quarantine weeds, more cost-effective in the early stages of infestation. In view of this, an urgent need to pay close attention to the study of the biology and ecology of  S. cryptandrus. In the near future it is important to carry out an assessment of limiting fact affecting its size and the speed of the processes of invasion species.
