In the article some results of complex physical and chemical researches of a wide spectrum metabolites grapes of grade Rkatsitely from ecotopes various high-altitude zones are presented. For the first time it is certain, that the ecological conditions of a foothill zone promote more intensive synthesis of carbohydrates, vitamins, titric acids, phenolic substances, amino acids and to greater accumulation of mineral elements, than on plain. High concentration of biologically active substances allows to recommend grapes from foothills for reception of products with greater food advantages. Use of the grapes which is grown up at heights of 200 and 265 m above sea level is shown, that, for manufacture of champagnes wine materials considerably will improve quality of a champagne.
The article is devoted to the evolution of the content of the conception of sustainable development reflecting the transition from technological to anthropocentric principle. The role of educational factor is mentioned; the forms of multicultural and multilingual education, the most convenables for preservation of the cultural variety and linguistic heritage are described; the experience of creation of the similar educational system in RNO-A is indicated.
The special content of microorganisms (fungi and bacteria) caused root decay in grape infected by phylloxera was studied. As the result of investigations it was detected that in infection of grapes with microorganisms in Azerbaijan condition take place following species: Су1 radicicola Wr., F. oxysporum Schlecht., Gl. verticilloides Pidopl. from phytopatogenic fungi; Ps. liquefaciens Migula, Bac. mesentericus vulgatus Flugge from phytopatogenic bacteria; P. citrinum Thom, P. cyclopium Westl., Rhac. vitis, Abs. vitis, Muc. Mucedo (L.) Fres., Mol. vitis from saprotrophic fungi.
The modern state of mountain and foothill pastures in Uzbekistan and their transformations under the influence of man's agricultural activity are dwelled on in this paper. The main reasons of degradation of the planting surface consequences of the republic's mountains have been determined. On the example of Uzbekistan the authors have found out the range of natural and agricultural consequences of mountain deforestation. The authors think that for the stable improvement of mountain and foothill pastures in Uzbekistan the forest melioration is the most effective way.
It has been revealed that there is a close connection between landscapes, soil types, thermal and hydrothermal conditions on Pamir. General schemes of the distribution of soils and vegetation as dependent on the distribution of the sum of active temperatures and the degree of climatic moistening (Ivanov-Vysotskii humidity factor) in the Pamir Mountains are suggested. It is shown that the development of particular types of soils and vegetation communities in all vertical thermal belts, except for the cold belt, is mainly controlled by the humidity factor. The information about soils of the Western Pamir is necessary for introduction of scientifically-based systems of agriculture, land reclamation, improvement of hayfields and pastures, development of agrotechnology system and planning and realization melioration.
Features of mountain territories and their problems which demand reconsideration of economic policy of development of all republics of Northern Caucasus, coordinated with the concept of transition of Russia into the model of steady development of economy are considered. The basic problems of social and economic development of mountain territories of Northern Caucasus and the corresponding macroeconomic conditions which will allow to provide transition to the steady economic growth are formulated.
In the article Speed of an ice-stone mass at the catastrophic tails of the Kolka glacier is appraised with model of viscid liquid free flow. The results are in good agreement with seismic supervisions .
This study was carried out during 2007 and 2008 in the vineyards of Ardebil province of Iran to study the biology and the epidemiology of Uncinula necator, the causal agent of grape powdery mildew disease. The study concentrated on the survival and the initiation of primary inoculum of the fungal causal agent. Results of this study and the new findings on the biology and epidemiology of U.necator may be of national and international interests for the management of powdery mildew disease which is one of the most destructive diseases around the world including Iran.
The paper addresses the issues of transboundary cooperation of protected areas (PAs) in the Altai-Sayan Ecoregion, located within Russia, Kazakhstan, China and Mongolia. High biodiversity, presence of globally endangered species as well as a number of threats (transboundary infrastructure projects and pollution, decrease of population of rare species, etc.) determine the need for transboundary cooperation of PAs. For the Altai region this idea was firstly suggested in 1998. During this period several projects on the planning of transboundary PA were accomplished. The case study of Katunskiy Biosphere reserve (Russia) and Katon-Karagaiskiy National Park (Kazakhstan) shows major problems and perspectives of transboundary cooperation.
Sclerotinia sclerotiorum, the causal agent of stalk rot, is a problem of sunflower (Helianthus annuus L.) production in Iran under irrigation fields in West and East of Azerbaijan and Ardabil provinces. One hundred and eighty six isolates of S. sclerotiorum were obtained from fields in West and East of Azerbaijan and Ardabil provinces during 2007-2008. After 186 isolates were paired, 26 MCGs were distinguished. 14 MCGs consisted of two or more isolates (MCG 18 had 23 isolates) and the remaining 12 MCGs were each made up of one isolate, compatible only with itself. In most pairings, mycelial incompatibility was not detected by the presence of a red reaction line, instead, there was, usually, an interaction zone of sparsely mycelium and also reaction line was visible as a abundant, tufts, white patches of aerial mycelium in the reaction zone on the colony surface. This study has demonstrated that West and East of Azerbaijan and Ardabil populations of S. sclerotiorum from sunflower fields are made up by various and different MCGs and also Sclerotinia isolates from three provinces were incompatibility between each other.
