USE OF EPIN-EXTRA, R PREPARATION ON SEED PLANTS OF ONION
Description
An important element in the technology of growing seed plants of onion is the use of physiologically active substances to protect plants from frost in early spring growing season. Damage to plants during this period affects seed production. In the experiment we used preparation called Epin-Extra R, with which the leaves of plants were treated a day before expected frost. Test results have shown high efficiency of preparation in the field and in the film unheated greenhouse. Treatment helps to balance the negative impact of low temperatures and obtain an additional seeds yield 92-95 kg / ha more compared with the control, due to the increase of seed of productivity of plants to 3.2 g

Description
The research results on regeneration activity of wilding cuttings of phylloxeraresistant varieties of grapes influenced by heteroauxin treatment are analysed in the article. The preliminary studies were held in All-Russian research institute of viticulture and wine-making of Ya.I. Potapenko using cuttings of 3 grape varieties – Berlandieri x Riparia Cober 5bb, Riparia x Rupestris 101-14 and Berlandieri x Riparia CO-4. The cuttings were soaked during 48 hours in 0,005 % heteroauxin and were implanted in sand in adjustable conditions of temperature, humidity and aeration. In 2012-2013 experiments were continued in Kuban State Agrarian University. The varieties Gravesak, RSB and Berlandieri x Riparia Teleki 5C were added to the experiment. Three-items buds were shooted in damp steamed sawdust in a film hothouse. In preliminary researches application of heteroauxin has allowed to increase root-growing by 20,3-40,0 %. The greatest increase of root-growing (40 %) was observed on variety СО-4, that is characterized by the weakest potential rhizogenesis activity, and the least (20,3 %) on control variety Cober 5 bb. Next researches show that treatment of cuttings basal ends by 0,01 % heteroauxin activated their regeneration process, that was expressed in: increase in sprouts length – variety 5 C, 101-14 and Gravesak by 23,1- 157,6 %; increasing of cuttings root-growing from 16,7 % on variety 5C to 60,0 % on variety Cober 5 bb, the quantity of cuttings with not fewer of 3 roots from accordingly 13,0 % to 54,7 %; increasing of roots from 0,7 on variety СО-4 to 2,7 on variety 101-14 or in 1,7-2,7 times. The application of heteroauxin on variety RSB did not show positive results, because of the variety peculiarities

FASCIATION IN NATURE AND IN EXPERIMENTS
Description
The phenomenon of fasciation on the example of higher plants was considered. The effect of fasciation on the various particularities of plants has been shown. The numerous examples of the different groups of plants with fasciation bodies are given. We have demonstrated that the phenomenon of fasciation is more common for cultivated plants than for wild. In most cases, fasciation is considered as an exceptional phenomenon. A number of authors have distinguished fasciation to inheritable and non-inheritable. The first is caused by internal reasons. The second is the influence of external factors such as insect damage, injury, weather conditions. The number of regularities was installed: reproductive bodies of plants fasciationing more often; thermophilic forms are more likely to be fasciation. The images of different cultures with fasciation parts are given. We discuss using the introduction of the term ”connаtions” as morphological abnormalities. Fasciation can be considered as a marker trait for the cause of this phenomenon with violation of ecological situation. The plants with morphosis, including fasciation of the certain parts of bodies, can act as indicators of environmental pollution. The study of the phenomenon of fasciation in higher plants can be regarded as a method of breeding for large fruit size. From one side, to establish the adaptation abilities of newly created genotypes. Thus, the phenomenon of fasciation has affected many areas of science. On the other side, it is proof of the violations caused by environmental factors. On the other hand, it is hereditary reasons, and can also serve as a model for studying morphogenesis

EXPLORING THE POSSIBILITY OF OBTAINING PECTIN EXTRACTS OF HIGH PURITY
Description
The article describes a possibility of obtaining food pectin extracts of high purity form secondary raw materials such as sunflower anthodiа. The relevance of the use of pectin extracts as independent products or as an ingredient in food products for therapeutic and prophylactic purposes is determined by the high complexing ability of pectin substances in the dissolved form, in comparison with the commercial powder pectin. The use of pectin extracts reduces the cost of the final product by reducing the number of technological procedures. As dried plant material is mainly used for the production of pectin and pectin extracts, the article presents the study of the swelling process of dried and crushed sunflower anthodiа. It is established that the inclusion of the swelling process as a separate technological process for the production of pectin extract from the sunflower anthodiа is impracticable. The study on further processing of vegetable raw materials by electroactivated water system (EAWS) to reduce the content of ballast substances in raw material in relation to pectin and increase the purity of pectin extract is also presented. Some processing options of sunflower anthodia with EAWS of various рН were considered as well. The decrease in the content of dry substances in the processing of plant material that characterizes the decrease in the number of ballast substances is shown. We have also calculated the purity of the obtained pectin extracts

WAYS OF FURTHER MODERNIZATION OF VEHICLES FOR AN AGROINDUSTRIAL COMPLEX
Description
The role of transport in agricultural production is considerable. It is a connecting link in a single technological chain of the agroindustrial complex of the country (RF AIC). In intraeconomic transportation in the RF AIC, along with cars, we widely use tractors. Rational application of wheeled tractors in intraeconomic carriage substantiates the possibility of their movements both on asphalted and dirt roads. A specific share of tractor transport in domestic agriculture amounts 22-27% of the total transport transportations and 50-60% of intraeconomic carriage. There is a high level of the usage of tractor transport in Western European countries and in the United States. In farms of leading Western European countries (Germany, Italy, France and others.) there is about 70-90% of intraeconomic carriage performed by tractor transport. One of the most substantial and difficult tasks is to fight with damage and losses of agricultural production, in which a very responsible role has been assigned to automobile and tractor transport as an important link in the AIC. According to the analysis of materials for the preparation and use of potatoes and apples, more than 15-20% of the products do not reach the consumer. Low quality of the use of vehicles during transportation is a problem. Transport costs in the prime cost of produced products in rural areas reach 30-40% or more. Lowering them will further influence the development of the agroindustrial complex. Thus, the creation of new of scientifically grounded decisions in designs of vehicles for intraeconomic carriage that enhance preservation and performance of potato harvesting and apples in the conditions of Russia's AIC is the actual scientific and technical task. Its solution makes a significant contribution to the development of the country, as well as it contributes to the implementation of breakeven, competitive manufacture

Description
In agriculture the issue of enhancing the efficiency of operation of internal combustion engines (ICE), reducing the costs of maintenance (TO) and repairing (TP) fuel supply apparatus (TA) using the improvement of methods and means of diagnosis is a topical in connection with the aging rolling stock farming and lack of investment. Analysis of the known TA diesel engine vehicles systems showed that the most widespread system is the divided type with multiplunger high pressure fuel pump (fuel pump), while the methods of its diagnosing are laborious, they require partial disassembly and have insufficient accuracy. The mathematical models that characterize the work of a high-pressure fuel pump (fuel pump) use a large number of parameters that significantly affect the quality of dynamics of the change of pressure values of diesel fuel. However, in the materials of previously published articles there were no issues considered assessing the extent of the quantitative impact, performance and features change in the sensitivity settings of the mathematical models on the simulation results, there are no recommendations on the degree of sensitivity and importance of each of the parameters. For a more accurate diagnosis of the fuel supply apparatus of a diesel engine it is advisable to use several methods of diagnosing. The article substantiates development of a mathematical model of a high-pressure fuel pump based on the analysis of modern methods of diagnosing of fuel equipment for autotractor diesel engines
