DEVELOPMENT OF MULTIPLEX SETS OF SSR MARKERS FOR GENOTYPING APRICOT VARIETIES (PRUNUS ARMENIACA L.)
Description
Genetic studies of apricot are the actual direction in the genetics of fruit crops. In this regard, the improvement of the collection of SSR markers for the genotyping of this culture is an objectively significant task. In a study for the 16 SSR-markers previously developed on almonds (PdUnchar2, PdSLD1, PdGMGT1, PdTrTFGT1, PdUnchar2, PdSLD1, PdGMGT1, PdTrTFGT1) and Siberian apricot (A3-72, A1-63, H2-22, A3- 7-1, H2-5, A1-7, A3-9, H2-45), approbation and evaluation of the prospects of using for genotyping Prunus armeniaca L. were performed. Approbation, performed on 3 varieties of different origin, revealed markers and their combinations optimal for their use. During the study, all tested DNA markers were grouped into multiplex sets, including 4 markers. This allows carrying out genotyping simultaneously on 4 loci in the formulation of one reaction. One marker (PdUnchar2) from the studied sample included in the multiplex set did not show amplification. Five markers gave a monomorphic product. The remaining 11 SSR markers allowed us to obtain polymorphic, cultivar-specific SSR fingerprints for all the studied cultivar. These multiplex sets are proposed for use in studying the genetic polymorphism of the species Prunus armeniaca L.

RESOURCE-SAVING AS A FACTOR OF INCREASING THE EFFICIENCY OF INDUSTRIAL FRUIT AND VINE GROWING
Description
The interrelation of efficiency of reproduction with rational structure of the organization and resource capacity of productive and technological processes is established. The need in imbalances of elimination for the organization of reproduction processes is caused. The main directions of efficiency increase of industrial fruit growing and vine growing are developed: the rational structural organization of productive and technological processes, the application of resource-saving technologies of crops cultivation, the decrease in level of chemical and technogenic impacts on agric cenosises. The criterions characterizing effective results and optimal resource capacity of technologies of long-term cultures cultivation are defined. The characteristic of decrease ways of resource capacity on the basis of new constructional decisions in the forming agric cenosises is given: in the industrial fruit growing is application of the unsupported cultivation of fruit plants providing the differentiated application of a wide range of rootstocks of the SK series which without influence on heredity of the grafted variety, reduce the force of plant growth, provide a fast fruitage and high productivity, resistance to biotic and abiotic stressor; in the industrial vine growing is the application of the formations of new type reducing the costs for the making of support-trellis construction, on the carrying out of agric and technological time-limits that is reflected in product cost and profitability of production of branch production. The main directions of resource-saving are systemically presented, the assessment of their efficiency in the industrial vine growing by the principle of a golden rule of economy" is carried out

IMPROVEMENT OF AGROTECHNOLOGICAL METHODS IN A FRUIT TREE NURSERY
Description
Agro-technological operations, achieved in the specialized fruit tree nurseries are directed toward the optimization of the seedlings cultivation conditions. The agro-chemicals application is one of the most important technological questions in production system. The method of the complex use of physiologically active materials with the nourishing salts is directed, in the first place, toward the development of the healthy, actively functioning assimilation apparatus of the perennial plant, whose task – the balanced increase and the formation of reproductive organs already in the early stages of ontogenesis. In the article the results of work on introduction into the flow chart of the production of the apple tree landing material of bio stimulants and fertilizers of the directional effect are represented. Positive effect from the introduction into the diagram of nourishing salts of stamp N20P8K8+1,5Mg+9S in different combinations with the preparations: «lignogumat» of sodium, «lignogumat» of potassium, by ethane-1,2-dicarboxylic acid, by the natural stimulator of an increase «Silk» it was reflected in the level of the plants security of with mineral elements, it contributed to an increase on 5,7-10,2 % the diameter of trunk; the height of seedlings exceeded index in the control on 4,9-6,2 %

COMPARATIVE ASSESSMENT OF THE CLONE OF STOCK М9ЕМLA AVERAGEGROWING APPLE-TREE
Description
In FSBRI «North-Caucasus zonal scientific-research institute of horticulture and viticulture» (Krasnodar) there was carried out the comparative economicbiological study of the average-height apple-tree stock М9ЕМLA in comparison with initial weakgrowing stock М9 in manifold, nursery and garden. Manifold bushes of the clone M9ЕMLA is quite worse in force than the stock М9 and were less branchy. Output of standard per hectare of manifold at the clone M9ЕMLA was on 35,5 thousand units more, and а standard condition of cuttings - on 13,2 % higher, than at the stock М9. Cuttings of the clone were less spiked and better rooted. In the first field of nursery, the plants of the clone had a vertical growth of the central conductor, slightly weaved and were more suitable to inoculation. The output of standard plants, in the variant with the use of clone M9ЕMLA by the variety Champion, in average for 2006-2010 was on 3112 units/hа, and on the variety Prikubanskoye – correspondently on 2470 units/hа higher than grafted on the stock М9. The cost price of 1000 seedlings on the clone M9ЕMLA was on 1962 rubles less than on the stock М9, and the standard of profitability of seedling growing, on the contrary was on 14-19 % higher. In the garden the trees on the clone M9ЕMLA were worse in growth of trees grafted on М9: on volume of the crone on 0,4-0,6 m3 , in diameter of the stem on 9-12 mm, in dependence on the variety, independently on the fact that some trees on clone were more weaker than grafted on the stock М9, their productivity for 2011-2015 was higher as from one tree as from the unit of area. The intensity of fruiting expressed in yield in kilos from a tree on the unit of volume of the top of a tree on the clone M9ЕMLA was on 33-39% higher than at the trees on the stock М9

STABILIZATION OF MRNA CEREALS IN VITRO UNDER THE SILICON INFLUENCE
Description
The differential stability of mRNA is an important mechanism for posttranscriptional regulation of gene expression in eukaryotes. Messenger RNA stability is controlled by specific genes and growth conditions. The review examines the theoretical possibility of mRNA stabilization in vivo as a consequence of replacing carbon atoms (C) or phosphorus (P), composed of nucleic acid on the silicon (Si) atom. During isolation of poly-(A)+mRNA from plant tissues by the two-cycle affinity chromatography on poly-(U)-Sepharose, regular changes in poly- (A)++mRNA yield were observed. The changes varied both with the plant genotype and growth conditions. Celite treatment of heated and unheated total RNA preparations from developing corn kernels and from green and etiolated wheat seedlings. Messenger RNA that differed in the length of poly- (A)-sequences was used for hybridization. It is evident that a reduction of poly-(A)-length causes alterations in spatial structure of mRNA, and associated proteins and cations Mg++ become accessible to celite absorption. Heating promotes melting of secondary structure, already initiated, and increases the efficiency of mRNA stabilization by celite. Interpreting the facts interact celite with mRNA in vitro and stabilization of mRNA in vivo by cycloheximide with a modern point of view can be considered with the position research of the phenomenon of RNA interference
