Adventive weeds control using classical approach of biological protection against adventive species is not always satisfactory. A new method of the ragweed inhibition is developed that is based on shifting of the natural phenological stage of the phytophage growth. It makes possible to produce a large group of ragweed noctuidae under laboratory conditions on an artificial nutrient medium and to inundate weed infested areas with them by the time of the invader emergence
The results of laboratory studies of accumulation of gross forms of heavy metals, the total rate of accumulation (SPN) in the soil under the canopy of woody landscape parks of the town of Novocherkassk are presented in this article
We investigated the basic soil types (brown, brown wood) of foothill zone of Dagestan. We revealed that the distribution of nickel, chromium and lead in the soils depends on several factors: soil-forming rock, physical clay, humus and pH. We defined the background content of heavy metals in the studied soils of the region
The article describes the theoretical concept of environmental reclamation of nuts in the bio productive land reclamation of agricultural lands. Theoretical propositions formed the basis of technology of creation of bio productive plantings of walnut and black nut
By the methods of classical histology and modern histochemistry in differential assessment of various albuminous components, we have revealed a number of new regularities of age dynamics and distribution of some albumen in cells and tissues of musky preputial glands of muskrat males inhabiting under conditions of Baikal region ecosystem
The results of studies of copperhead (2008-2011) in the Volgograd region are shown, geographical distribution, habitat association, environmental characteristics are examined; morphological characteristics of species in the study territory are given
The results of studying the ordinary pine condition in geographical cultures of the Central forest-steppe are cited in the article. The general pattern of the ordinary pine intraspecific variability is represented. The data of origin influence on safety, efficiency, qualitative adjectives is presented. The pattern of ecotypes adaptability to new environment conditions is presented
The review presents some data on structural and non-structural, regulatory proteins and enzymes of African swine fever (ASF) virus. The variety of the virus biological characteristics is substantially caused by proteins belonging to multigenic families. It is suggested, that the protection development at ASF is provided not only by the membrane proteins, but also by the regulatory ones
Different aspects of applying the pollen analysis were studied in plant breeding. Fertility, pollen viability, change of pollen morphological characteristic were used by basic characteristics. Connection between pollen analysis and plant reproduction potential have been analyzed
The immunologic characteristics of 18 domestic winter wheat cultivars to Transcaucasia population of yellow rust pathogen have been studied. 251 resistance sources to Puccinia striiformis have been detected among 468 studied soft wheat samples from Vavilov ARRIP collection. The efficiency of known resistance genes (Yr) to Transcaucasia population of yellow rust pathogen are estimated
