The results of the study of the dynamics of physiological and biochemical parameters of the immune response of grapes to fungal pathogens are given in the article
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
Phytocenosis of the oak durmast and english oak on southern and northern exposition are studied and compared
In the article we have described the history of the studies and the modern features of fish community of the Black sea's river Durso (the length 14 km). It was established, that in present time the river includes only seven species of fishes from three ecological groups: freshwater (five species), saltwater (one specie) and marine (one specie). A bleack (Alburnus alburnus) and Colchis minnows (Phoxinus phoxinus colchicus) dominate by quantity in the structure of Durso river fish community, bleack and Prussian carp (Carassius auratus gibelio) dominate by biomass.
The negative changes of Durso river conditions were found in compare with the last years. First of all, it appears in biological pollution of fish species allochthonous for this river. In the period of the Durso river monitoring (1935–2014) it was established the distinct raise of allochthonous components with parallel reduce of variety of autochthonous fresh waters rheophilic species. The main reason is the building of reservoir in upper flow of the Durso river in 1976. The additional negative factor influence on of the Durso river fish community is the falling down of the water level during the important period of fish lifecycle. The best condition of fish community is in the middle part of the river were reaches combine with the cold springs and powerful flow
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.
With biotechnology development, working out and introduction of the new technologies focused on an intensification of a complex of difficult biochemical transformations which proceed in meat raw materials by manufacture smoked sausages became possible.
One of such ways is introduction of starting cultures in a compounding of sausages. In this article we have presented the researches of perspective microbial strain and the choice of the strain for creation of starting cultures
This article presents the data of chorological analysis of the flies’ fauna (Insecta, Diptera) of the Kamishanova Polyana Nature reserve. The analysis of distribution of 432 species of the reserve allowed to identify the 4 groups and 16 types of areals
The article presents the results on the effects of
Imazethapyr herbicide on aquatic organisms. The
chronic toxic effects have been studied of the
imidazolinone herbicide in a concentration range of
0.4 - 1150 mg/l to the representatives of various
groups of aquatic organisms: zoobenthos – great
ramshorn snail (Planorbarius corneus), zooplankton
- Daphnia (Daphnia magna Straus), phytoplankton -
protococcal alga (Scenedesmus guadrigauda) and
macrophytes - higher aquatic vegetation (Elodea
canadensis Michx). It is shown that the herbicide
does not have a pronounced lethal effect to aquatic
organisms tested. Their respective LC50 values are
> 1000, 680, 510 and 910. Elodea is shown to be
most sensitive to its sublethal effects (decreased
growth of lateral and main sprouts at a concentration
of 10 mg/l and more), reduced fertility was observed
in Daphnia at a concentration of 300 mg/l and
above, and as to the great ramshorn snail no
sublethal effects have been revealed for all the
concentrations studied
In this article, we discuss the results of the research of
quality characteristics of Russian and foreign rice
varieties. Possibility of using data in characterizing
germplasm from collection is discussed
The clone selection has very outstanding position behind the actual problems of modern viticulture in the world and in our country. This problem usually has the primary importance behind the scientist who works with grape in all the countries such as USA, German, French, Spain, Italy, Hungary, Bulgaria, Moldavia, Ukraine and etc. In our country last years some positions becomes solving in the plane of scientific research work. Consequently, in the article the history and the situation of clone selection of grape on the Eurasian continent is widely covered.
