We have described the theoretical assumptions and methodological solutions in the present review. They are innovative possibilities in the development of laboratory methods for assessing biological features of grain during the selection process
A new science – genetics was born in the first decade of XX century. The part of G. Mendel as a founder of this science is showed here. Also here are scrutinized tasks of scientists - biologist, who assist to the making and progress of genetics
The questions of use duckweed as green vegetable are considered in article. The structure of types of duckweeds, their biological features, distribution in the world and in the territory of the Krasnodar region is shown. Possibility of their use as biotesters and
bioindicators of the water environment, as analytical system for the analysis is shown. Questions of use of duckweed in artificial conditions as well as requirements to the content of culture are considered
The morphometry of leaves of the Kuban wild-growing lianas of grape, as we know, is not learnt till now and availability of quoters of pure subspecies of Vitis vinifera silvestris Gmel is not demonstrated., though suppositions about this information soared in the scientific environment as old as Adam [5]. With the advent of a direction of morphometry taxonomy there was a necessity of accurate bracing of a current state of a genotypical diversity of lianas and biological polymorphism of leaves for link establishment silvestris - silvesatis - sativa
There have been examined the methods for estimating the degree of heavy metal contamination in soils. There have been revealed some discrepancies that concern estimation of soil contamination degree and calculation of consolidated figures for chemical elements contamination in soils stated in effective
normative documents. The formulas for estimation of summary soil contamination stated in normative documents reveals considerable discrepancies that do not let give an objective estimation of dangerous concentration of heavy metal. We offer estimation of concentration of several chemical elements not by summarizing their concentration but by estimating their excess in relation to rock or its concentration in soil taken as a background
The article discusses the features of the pathogenesis of micromycetes Gibellina cerealis Pass. in vitro
In the article the characteristic of age states of the rare species Oxytropis baschkirensis Knjasev (Fabaceae) is described in South Urals, and also biometric parameters of generative plants are resulted and their variability is estimated
In this article the changes of age and sexual structures of populations of a lake frog from ponds-evaporators of sugar factories are show. The are the low number of adult animals, the increase of frogs of morpha maculate and females
The characteristics of meadow-wood typical soils, located on territory of lowland of Tersko-Sulaksk and Hunzahsk mountain area of Dagestan are given. Results of research of the contents of vitamin C (an ascorbic acid), P-active connections and mineral substances of iodine, manganese, copper and zinc in the hips, growing on above-stated ground are resulted. The received data testify that the meadow-wood ground of Tersko-Sulaksk lowland promotes accumulation of iodine in a dog rose, and the similar mountain ground in a greater measure influences synthesis of vitamins and the contents in hips of mineral substances. The value researched biochemical connections for a human’s organism of the person, the is shown and the comparative estimation of their structure in a dog rose growing on meadow-wood grounds, being on various heights above sea level is given
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
