The article gives the estimation of the influence of Agro industrial complex on the state of small water basins. Hidrochemical and microbiological researches of rivers at their main stages of water regime were conducted. Seasonal fluctuations of main polluting substances were revealed. For microbiological estimation of the water quality in investigated water basins, there was done the calculation of the total quality of microorganisms. At the same time, a quality control of sanitary demonstrative microorganisms was done
Daily watering (for 7 days) with probiotic "Provagen" at a dose of 14 g/head and complex probiotic (14 g/head) with chitosan (0.8 g/head) has optimized homeostasis, as evidenced by a strong tendency to reduce to the normative values of the relative content of neutrophils in the blood of calves
The results of ecological modeling of regularities of formation of vegetation sand massifs of Don basin are presented in the article
It is shown that under in vitro conditions, regenerated plants of Lilium caucasicum cultivated in the light of varying intensity and spectral composition didn’t have the same biometric parameters (length and width of leaves) or number of micro bulbs. There were established some specific effects of the two main areas
of photosynthetically active radiation - blue and red on the growth and development of the plants as well as on the content of photosynthetic pigments
There are comparative characteristics of agronomic biological qualities of bulls of Kazakh white and Kalmyk breed and their crosses
Plants images in painting, mosaics, scientific illustration, herbals and books or agro-botanical iconography is a valuable resource of the information about the history of the spread of various phenotypes, such as turbanoformis form of pumpkin in the past century in different regions of the world
Radioecological risks of bovine leucosis spread among cattle in Chelyabinsk region are estimated. The obtained data can be used for simulation modeling and the forecasting of leucosis prevalence in the conditions of ecological troubles
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
In the given work there is information about peculiarities of distribution and phytocenotic placement of the endemic of Dagestan flora Helianthemum daghestanicum Rupr. Twenty five
locations of the species are detected and four of them are new ones. Altitude levels of its spreading are defined more accurately – 350 – 1750 m. It is notified that basic types of vegetation, where Sunrose Dagestanian can be met, are communities of mountainous xerophytes and mountain steppes with domination of Botriochloa ischaemum and Salvia canescens
The results of study of production process of winter wheat amid of changing of agro ecological conditions such as seeding time, level of initial fertility, fertilizer system and variety throughout 3 year-research are shown in the article. Five hypotethetical systems are pointed out with the help of factorial analysis. Detached varieties and research years are pointed out in terms of their factorial influence
