BIOLOGY OF SEED GERMINATION OF SOME SPECIES OF FAM. ROSACEAE JUSS
DescriptionWe have studied the germination and the nature of germination of seeds of 20 species of FAM. Rosaceae. A wide range of germination characterizes their seeds: rapid, slow, with very poor or no germination. Laboratory germination of seeds stored at room temperature for 6-7 months have 80-100% - 8 species, 66-77% - 3, 1-9% - 4 species and 5 species did not germinate at room temperature, they need special conditions for germination

BIOLOGICAL AND PRODUCTIVE RESOURCES OF LACTATING COWS AT DENITRIFICATION
DescriptionThe article presents the results obtained in the process of two scientific-practical experiments carried jut on two milk cows (Shvitskay breed) aimed at the antioxidants detoxication properties and mould inhibitor revealing. This factor is actual in the Republic of North Ossetia-Alania as the intensive technologies of the fodder crops cultivation using the nitrate fertilizers are widely applied in the region leading to the excess nitrates and nitrite penetration into the animals’ organism. During the first experiment, the antioxidants of epophen and vitamin C were added into the ration of the lactating cows with the subtoxic dosage of nitrates both separately and in complex. The complex feeding proved to increase the milk productivity, the fat mass and protein mass in milk while reducing the fodder expenditure per product unit. Beside, the lactating cows revealed the digestive and intermediate exchange betterment and the reduction of nitrates and nitrites level in blood. The second experiment helped to study Khadoks antioxidant and mould inhibitor called Mold-Zap efficiency use for the nitrates and aflotoxicin B1 detoxication. The researches showed that the complex admixtures of the said preparations introduction into the rations of the animals increased the milk productivity, fat and protein content and reduced aflatoxineM1 content. The cows activated the digestive and intermediate exchange, accompanied with the nitrates and nitrites level reduction in the organism

BIO-UPDATING OF MEAT RAW MATERIALS FOR THE PURPOSE OF MANUFACTURING FUNCTIONAL PRODUCTS
DescriptionThe products containing consortia lactic and bifidobacteria, play an important role in a food of people, especially children, persons of advanced age and patients. Microorganisms - active producers of the useful substances capable to transformation of connections natural or synthesized by a chemical way in substances valuable to the person. In this article the researches of the influence of consortia of microorganisms on meat raw materials are presented

BIOMONITORING OF CHEMICAL ELEMENTS CONTAMINATION OF RECREATIONAL AREAS OF ROSTOV-ON-DON
DescriptionThe article presents the data on the chemical elements content in soils, plant leaves and lichens of three squares in Rostov-on-Don. The calculation of the total index of soil contamination by chemical elements finds that soils of the square are characterized by a low degree of contamination

Description
The article provides information about phytochemical investigation, medical and nutritional importance of fruits of Capparisherbacea L. including CapparaceaeJuss. family in the area of the Nakhchıvan Autonomous Republic. Some solvents had been applied, fruit and leave extracts had been bought. The purification and identification of content of plant extracts had been investigated with spectroscopic and chromotographic methods. The saponins, carotinoids, chlorophyll pigments and flavonoids had been revealed in the content of extracts. The extracts have been acquired from fruits of this species by use of polar and nonpolar solvents and the composition of extracts have been studied with different applied methods. The column and thin layer chromatography carried out in order to purification of contents and extracts were fractionation and Rf values were calculated

Description
The features of functioning of the reef modules are studied in the conditions of north and middle parts of the Caspian sea in the district of knocking down of depths. Quantitative descriptions of benthos associations are set in the district of setting of artificial reefs and in their zone of influence. The estimation of efficiency of module constructions is executed. Optimal materials and structural decisions, most suitable for the terms of district of researches are specified

BIOTECHNOLOGY OF TRICHODERMA-BASED FEED ADDITIVE WITH CELLULOLYTIC PROPERTIES
DescriptionIn the work, we have presented the information of elaboration of a manufacturing process of Mycocel feed additive with the cellulolytic activity for poul-try industry. Manufacturing process includes follow-ing steps: stock culture maintenance and storage of Trichoderma lignorum 81-17, growing fluid culture of microscopic fungus in sucrose yeast extract me-dium, feed additive with cellulolytic properties out-put and quality control, packaging, storage and disposal of waste. We have shown that the Mycocel is non-toxic feed additive for protozoa and warm-blooded animals (laboratory mice and quails). This study demonstrated total population livability in the experimental group with feed additive. Quail body-weight of experimental group was higher by 6% as compared to the control and feed consumption per 1 kg of live weight of bird was 3,58 kg, 7,5% lower than the control

BIOTECHNOLOGY – SCIENCE AND SECTOR OF AGRICULTURE
DescriptionThis article presents information about the features of biotechnology as the driving force of scientific and technological progress. The national programs of the leading countries of the world, it is one of the priority sectors, reflecting the level of the socio-economic condition of the society. Biotechnology is now successfully solves such vital tasks as providing food, the establishment of effective medicaments, obtaining fuel based on renewable raw materials, maintaining ecological balance, conservation of biological resources of the Earth. The development of agriculture in modern conditions is impossible without agricultural biotechnology. It is directly related to viticulture. Choosing an object of an integrated system (embryos, apical meristem, axillary buds), it is possible to clone plants, i.e. produce plants identical to the original. If the same as the object to use isolated cells or protoplasts, in this case, there will most likely altered versions, creating diversity for the breeder. Genetic engineering – the science of younger, since the establishment of the first chimeric DNA molecule. The origin of genetic engineering is rooted in the development of molecular genetics, biochemistry. These technologies, undoubtedly progressive, but their biological safety is still insufficiently explored and is a danger to all life on Earth. The leading Western powers carried out strict control over the introduction of transgenic crop plants, as they are in agrocenosis new biological risks that may adversely affect the plants, animals and humans. In Russia, as in other countries, have already adopted the law “State regulation of genetic engineering”
