ASSESSMENT OF ENVIRONMENTAL PERFORMANCE OF LARGE CITIES IN THE CONTEXT OF RAPID URBANIZATION
DescriptionThe article defines the basic characteristics of the environmental performance of urban areas. There was offered the system of environmental performance indicators, covering the basic characteristics of the environmental performance. There was developed the algorithm and calculating methodology of composite index of the environmental performance of major cities in the context of rapid urbanization. There was conducted the approbation of the methodology according to the data of major cities which are the administrative centers of the Russian Federation for 2008, 2009 and 2011. There was carried out the rating of major Russian cities based on the composite index of the environmental performance

FEATURES OF PLANT INTRODUCTION IN THE KUBAN REGION
DescriptionThe features of introduction of trees, shrubs and herbaceous species in terms of the Krasnodar region and the south of the CIS are analyzed, the specificity of this process for deciduous and coniferous species, and grasses at their development in the spring and autumn periods, the allocation of forming niches generative organs, microsporogenesis, etc. are discussed. Opportunity to adapt different kinds of herbs and species of shrubs and trees, taking into account seasonal development with allocation of exotic species in the annual cycle of vegetation critical periods for the growing season Kuban has been considered. The results of the horizontal and vertical introduction in the study of the imported seeds and planting material of different species of trees, shrubs and grasses are discussed

COMBINED PLANTING OF ANNUAL CROPS - IMPORTANT PROBLEM OF PRACTICAL ECOLOGY
DescriptionSelf-regulation of agricultural systems is based upon taking into account the interaction of their components released in variety of species and trophic relations; agricultural systems is diversified in towards a sustainable, productive and strategic development of the systems; one of the most promising areas of diversification of agricultural systems is considered to be an introduction to the practice of combining crops, known in agriculture for a long time, which shows us the nature. The most developed technology for creating combined crops is the practice of creating mixtures and the nature of the relationship between their different components

Description
In the process of the research we had accomplished an analysis of allelic polymorphism of self-incompatibility in pears in demand in the production and breeding of modern varieties of pears of North-Caucasian Zonal Research Institute of Horticulture and Viticulture collection of genetic resources. In the first stage the consensus primers PycomC1F and PycomC5R were used. With obtained data, after identification of the alleles studied in varieties using consensus primers an allele specific S5 and S8 DNA markers were used for confirming the presence / absence of data allele studied cultivars
