To control irrigation erosion, the artificial aggregation of soil by structure-forming materials was proposed in the article. The research was conducted for establishing the impact of the percent content of each fraction on soil cation exchange capacity
The ability of Phomopsis to transmit from affected seeds to plants has been studied in both anamorphic and teleomorphic phases of its development in the year of sowing. The sunflower lesion with Phomopsis affects not only the germination, but also causes the plant disease
The dynamics of α-, β-amylase and summering amylase activity of single germinating spring barley seed is presented for the first time. It has been shown,
that the environment of seed growth period influences the development of ferments’ activity
We present a brief description and analysis of the weather conditions of 2005-2011 in North, Piedmont, and the Kuban Krasnodar fruit zones. In the course of many years of research, the optimal conditions for precipitation of water supply as one of the most im-portant factors in increasing the productivity of agro-phytocenoses in the region
In order to find compounds that increase sugar beet resistance to the adverse effects of herbicides, a series of naphthalenesulfonamides derivatives have been synthesized. The protective effect of new compounds for the herbicide mixture Betanal, Lontrel and Super Zeleke was studied in field conditions. The effect of pyridylhydrazones on the synthesis of photosynthetic pigments in leaves was investigated. Substances with a high protective effect were found
The results of long-term population-genetic studies in wheat pathogen system “wheat – dangerous disease pathogens” associated with the study of the structure, variability, forecast of plant pathogen development and the host plant genetic diversity are introduced.
It is shown that it is necessary to develop polymorphic genetic disease resistance of plant populations to rehabilitate the agroecosystem phytosanitary state, which is possible only on the basis of broad genetic diversity of source material, taking into account the intraspecific differentiation of pathogens and tendencies of the changes
This article is a review work where the role of microelements in life of plants is observed and theoretical and practical issues concerning application of complex microfertilizers enhancing productivity, quality of seeds and grain on rice crops are highlighted. The complexions of the metals used as micronutrients, are an effective form of trace elements and means of regulation of the production process of agricultural crops as seed treatment before sowing, and when conducting foliar vegetating plants. Their inclusion in the system of fertilizer rice to balance mineral nutrients necessary for plant life, providing increased productivity, quality seeds and grains
Nicotiana tabacum and rustica are facultative self-pollinated plants, therefore, because of pollination peculiarities, specific methods are applicable to growing seeds of this plants. Researches on mass, individual and family, recurrent methods of seeds selection for productivity and sowing properties are carried in the institute for revealing most efficient methods of getting seeds. Seeds growing system for Nicotiana tabacum and rustica is a part of general seeds growing system for all agricultural plants and consists of breeding, testing new sorts, mass reproduction of seeds with retained biological and productivity properties, seeds harvesting and controlling their sort and sowing properties. Primary growing of nicotiana tabacum and rustica seeds is carried by individual and family or recurrent selection and further testing of chosen plants, distinctive for this sort, on economically valuable and biological properties. Peculiarities of each zoned sort are kept by retaining its primary genome with constant selection of highly productive genotypes, specific for this sort. Well-organized seed growing system leads to sort potential revealing. Biotype composition of sort is obviously changing in a few years, so primary seeds growing system should be constantly improved
There were described the rice varieties created in Russia for production of children’s and curative nutrition. Among them are waxy varieties as Viola and Violetta, long-grained – Snezhinka and Avstral and red-grained – Mars as well. There were cited the agro biological characteristics of these varieties
The article presents the results of three-year researches of root-formating ability of grafts of 9 resistant table and technical grape varieties of native and foreign selection at their rooting in water.
Among studied indexes of root-formaing ability of grafts, the best varieties were Moldova, Lyana, Riton and Pervenets of Magarach
