DEVELOPMENT OF PROTEIN ENZYME FEED ADDITIVE FOR POULTRY FARMING
DescriptionThe research work was conducted at the Research Laboratory of Biotechnology, Biochemistry, Biophysics Department of Kuban State Agrarian University. The main purpose of this study was to select the most productive type of fungus of a genus of Trichoderma and optimal nutrient medium on basis of a waste of reprocessing of soy for acquire of protein enzyme feed supplement. For selection of a fungus of a genus Trichoderma used 3 types: Trichoderma viride, Trichoderma lignorum, and Trichoderma harsianum. We used 3 types of nutrient media as a carrier for micromycete, which were based on soy okara and the additional sources of reprocessing of raw plant material – husk of a sunflower, husk of wheat (bran) and husk of rice. The results demonstrated the benefits of using the nutrient medium based on soy okara forms and husk of a sunflower fungus to enhance Trichoderma lignorum production

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

APOGEOTROPIC SHOOTS OF CEREALS
DescriptionApogeotropic shoots of cereal different of wide range of types of shoots, noticeable differences on characteristic, features of development, their role in the herbage, the seasonal dynamics of crop formation, experiencing noticeable effect on the reaction conditions of soil fertility and humidity. Multiyear cereals in the process of shoot formation form the generative, hidden generative, elongated, short side and underground runners. Multiyear cereals are widely distributed throughout the world, including the tribe Antropogoneae, Chloridaeae, Maydae, Peniceae, Tripsaceae, Festucoideae and others that presented in different parts of the world, and perennial and annual forms. Many cereals are allocated notable longevity, which is largely determined by a wide adaptability to vegetatively propagate. Between northern and southern grasses differences are observed throughout the development of individuals, beginning with emergence. In the southern cereal first sheet has a lancet or ovoid shape and bent at a right angle to his vagina, it is the northern linear subulate form. Cereals are different typology of different shoots. Most large divergence is characterized with erect shoots in both groups of cereals

Description
The analysis of the variability dynamics of recombination frequency in the population of splitting F2 interspecific and intraspecific tomato hybrids has been carries out. It was discovered that recombination frequency depends on the components of cross breeding. It has been established that it is reasonable to use mutant forms of Мо 393, Мо 628 and interspecific hybrid F1 Мо 628 × L. esculentum var. racemigerum in selection process as an inductor of genotypic variability

EFFECTS OF GROWTH REGULATORS ON ROOTING CUTTINGS OF SYRINGA (PHILADELPHUS L.,PHILADELPHACEAE)
DescriptionIncreased range of Syringa in landscaping is a topical issue. They are very decorative shrubs, more and more widely used in landscape design. Study of vegetative propagation of plants, with the use of growth regulators, was conducted to identify the most perspective stimulator and to reduce the terms of the finished product. Syringa refers to bad rooting cultures. However, the methods of green propagation of cuttings with the use of growth stimulators not only propagate a culture, but also increase the yield of landing products. The article considers the technology propagation by cuttings of this promising shrub. It also shows the effect of growth stimulators: radifarma and HB-101, used for soaking of cuttings. According to the research, we have found an apparent benefits effect of the processing of cuttings with the stimulators on growth and development of root system. The analysis of the tables of rooting rate of cuttings shows the positive development of cuttings in the processing of the growth regulators. We have obtained the experimental data allowing to define which varieties distinguished by the greatest rooting and duration rooting among all the studied cultivars. Thus, the studies show that the use of growth stimulators with propagation of Syringa cuttings is an effective way of reproduction
