The theoretical analysis of the problem of disclosure of mechanisms of mutual influence of inoculative components on utility signs of the inoculate fruit-trees is carried out. New approaches of use of methods of biometric genetics for a prediction of their productivity according to characteristics of varieties and a rootstocks are offered
Climatic cycles associated with global phases of create gasses are the reasons of oscillation ecosystems and their constituent. Ecological capacitance of systems increases or decreases due to the appearance of new ecological niches, which creating favorable conditions for expanding or narrowing opportunities of adapting new types of organization of living organisms and their significant changes. Conjugacy of the biological evolution of living organisms with geological crises and periodic variations in solar activity is observed. Direction in the development of plant life forms since the beginning of their occurrence was quite varied. The most deeply the development of life forms was developed for flowering plants, starting from of different groups of gymnosperms. The main reasons for selection of life forms are due to challenges facing researchers
Balance of heavy metals in the topsoil describes their content at admission and take-out for a specific period of time. Sources of heavy metals in the soil are their admission with atmospheric precipitation, sowing material, dust, organic and mineral fertilizers, as well as other components. Take-out of elements from the soil is taken into account with a crop (grain yield of green mass, roots, etc.), as well as with the removal of water and wind erosion
In the article, we have proposed regional environmental standards for heavy metals, oil and oil products in the main soils of southern Russia
The objective of the present study was to investigate the supplementation effect of different treatments of whole cottonseed and full fat soybean on the diet of dairy ewes and the milk fatty acid profile and conjugated linoleic acid (CLA) content. The results indicate for both diets it is most suitable to use the second treatment in order to increase the level of cis-
9,trans-11 CLA isomer in milk. In the level of trans-10,cis-12 and cis-9, cis-11 no changes were observed in neither of the diets.
Ecological factors have a great impact on transition of a fescue meadow to formation of a bush. The optimum mode develops at high daily temperatures, in the rarefied crops, at security with nitrogen and without salinization
The article discusses the growth and development of gerberas varieties of Dutch and Turkish breeding on different substrates when growing them in volumetric technologies in the conditions of glass-covered ground
The article represents the results of African swine fever virus adaptation to continuous cell lines. We determined the conditions required for the adaptation and selected the cell lines most permissible for the virus proliferation
The research was made on the territory of the Internal mountain Dagestan. There were found 190 species of Oribatida belonging to 83 genera; 1 species isdetermined and scientifically described for the first time [3], 2 species are registrated in the Caucasus for the first time [1, 2, 4], and 10 species are first found in Dagestan [2, 4], 15 species are endemic Caucasus species [4]
As the result of the work, the test of microsatellite DNA markers for the identification of genomic polymorphism between apple cultivars Florina, Golden Delicious and clonal forms has been done. With the high level of intervarietal polymorphism, studied DNA markers showed no allelic differences between varieties and their clonal forms
