The accumulation features of radionuclides in the epitaphic pylaisiella moss (Pylaisia polyantha) in the territory of the city of Rostov-on-Don have been considered. The specific activities of 137Cs, 226Ra, 40K, and 232Th in the samples of moss, soils, and aerosol air have been compared. The capacity of Pylaisia polyantha to accumulate radionuclides has been estimated for four radionuclides (137Cs, 226Ra, 232Th, and 40K) with consideration for the background level. On the basis of radionuclide analysis, zones in the city of Rostov-on-Don with the highest accumulation coefficients of 137Cs, 226Ra, 40K, and 232Th were revealed. These were primarily the zones with both industrial and traffic loads and the motor transport zones
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 dependence of the grass cover state of the golf courses from the soil properties was observed. The soils named “replantozem” are the basic soil of gaming zone of "fairway". It is shown, that the heavy particle size structure with a predominance of clay particles is unfavorable to the lawn. During the golf course construction, natural soils were ameliorated with high sand content. This new made soils ensure the formation of better grass coverage despite the low humus content
The article presents the results of studies on the effect of dietary supplements «Kumelaсt» and «Laсtumin» on the microflora of calves. Prepara-tions stimulated proliferation lactic acid microflora, which depressed proliferation of opportunistic or-ganisms, which prevents the calves from diarrhea
In this article botanical and morphometrical characteristics of four wild-growing biotypes of Azerbaijan, growing on the Nakhichevan plain - original natural reserve of the richest vegetable gene pool of Eurasia are listed. Unique lianas are discovered, featured and listed under titles of Ajryndzh, Dary-dag, Ilandy-dag and Ordubad. Their comparison on 40 arguments of leaves with reference Vitis vinifera silvestris Gmel. triune herbarium of Russia and Ukraine is resulted
This article discusses the actual problem of using SSR-markers in studies of the genus Prunus. We have examined the works on the most important cultures of genus, collected and analyzed contemporary literature of the subject. Data of the initial stage of Prunus SSR-based genetic diversity study in the North-Caucasian region has been described in the presented publication
The research work was conducted on the tomato hybrid F1 Мо 755 × L. esculentum var racemigerum (Lange) Brezh. The individual characteristics of the reproductive system of tomato F1 hybrid were studied for their further inclusion into the selection programs. The dynamics of these factors in regard to the clusters in the tomato inflorescence was investigated.
The results of the morpho-ecological adaptations of imago carabidae researches in Tersko-Kumsckay lowland of Dagestan are exposed in this article. The species composition of carabidae in area was classified according to the Sharova’s system of living form and the detailed analyze has been done in this work
The article considers the issues of international spread the fruits of bottled gourd. Analysis of polymorphism of lagenaria fruits have been made on the basis of images of the paintings and sculpture, marked characteristic features of each country. Issues of selection on the basis of the trait of fruit form have considered
In this article the influence of four nanometal oxides on tadpoles of lake frog in pure water and in low concentrations of sawage of sugar factory is considered. It is revealed the protecting action of three nanometals, characterized by an increase in growth rates and decrease in death rate of tadpoles in sawage of sugar factories
