The influence is shown for the race of yeasts to the dynamics of the fermentation of grape must, the composition of organic acids and aromatic of components. The races, which ensure obtaining high-quality winemakings material are presented
The article presents the average and optimal calendar dates of the main phenological phases exotic woody angiosperms in Rostov-on-Don. We assess the level of variability timing of individual phenological phases. The data obtained can be used to diagnose the prospects of exotic woody plants for the regional culture
We know, that in the development of the natural ecosystems of the Western Priazovye its biomass predominates. This ensures the maximum protection from noticeable changes of habitat. Basic succession defining a significant shift of energy flow in the direction to increase of their expenditures to maintain forming populations determined by broad specialization of natural systems on ecological niches, and their individuals have rather small size, the life cycles of many of them are very simple and short. The coastal strip of the Azov Sea has been seriously degraded due to powerful recreational load, especially in the summer. Presumably one should expect an increased anthropogenic load on ecosystems of this area. Quite obvious is a regularity of overload agroecosystem which occupies the territory between the river and other water formations. The relatively low productivity of agricultural systems of the Eastern Azov is limited by number of factors, among which the main place is occupied with the moisture, nutrients and high weediness of sown areas
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
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
The article provides an overview of materials of conferences on problems and prospects of the industry of cattle breeding
This work was carried out on the natural territories in the collection and of the Yakut botanical garden (JBG). The object of study was medicinal plants used in the treatment of cardio-vascular system. On the natural territories JBG we have noted 39 species of
medicinal plants. 26 species were studied in a culture
The results of a long-term research of the influence of various biologically active agents (a humic preparation Lignogumat and microbiological Baikal EM fertilizer) on a structural state and the enzymatic activity of ordinary carbonated black soil are presented. It has been established that biologically active substances
contribute to increased enzymatic activity, humus and improve the soil structure
Apogeotropic 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
Studying of perennial cereals of southern and boreal origin led to the allocation of plagiotropic shoots of rhizomes, stolons, that are placed in the soil or on the surface from the apical or lateral kidney of various structures with modified leaves, the beginnings of roots at nodes and developing of type kidney - lengthened shoots. Two types was allocated: type of solid finned cylinder and type of intermittent cylinder with scattered around the periphery of vascular bundles: first include cereals temperate regions and is characterized by separation from the epidermis continuous sclerenchyma ring, the second type (sorghum and millet) no continuous mechanical ring and vascular bundles relatively evenly spaced along the periphery of the shoots
