FEATURES OF THE EVOLUTIONARY DEVEL-OPMENT OF LIFE FORMS OF HIGHER PLANTS
DescriptionClimatic cycles associated with global phases of create gasses are the reasons of oscillation ecosystems and their constituent. Ecological capacitance of systems increases or decreases due to the appearance of new ecological niches, which creating favorable conditions for expanding or narrowing opportunities of adapting new types of organization of living organisms and their significant changes. Conjugacy of the biological evolution of living organisms with geological crises and periodic variations in solar activity is observed. Direction in the development of plant life forms since the beginning of their occurrence was quite varied. The most deeply the development of life forms was developed for flowering plants, starting from of different groups of gymnosperms. The main reasons for selection of life forms are due to challenges facing researchers

QUESTIONS OF PROTECTION OF SOIL IN THE AGROLANDSCAPES
DescriptionBalance of heavy metals in the topsoil describes their content at admission and take-out for a specific period of time. Sources of heavy metals in the soil are their admission with atmospheric precipitation, sowing material, dust, organic and mineral fertilizers, as well as other components. Take-out of elements from the soil is taken into account with a crop (grain yield of green mass, roots, etc.), as well as with the removal of water and wind erosion

Description
The theoretical analysis of the problem of disclosure of mechanisms of mutual influence of inoculative components on utility signs of the inoculate fruit-trees is carried out. New approaches of use of methods of biometric genetics for a prediction of their productivity according to characteristics of varieties and a rootstocks are offered

USAGE OF THE BACTERIAL PREPARATION “DESTROIL” FOR DESTRUCTION OIL POLLUTION IN FRESH WATER
DescriptionThe researches of degradation of oil products in fresh-water reservoirs at the expense of the activity of petrooxidizing bacteria of Acinetobacter speivs SN-2 are carried out. The decrease in the content of oil products in 25 days prior to maximum concentration limit (0,05 mg/l) and the increase in concentration of oxygen in the reservoir are defined

ISSR ANALYSIS OF PINUS SYLVESTRIS TREES APPURTENANT TO DIFFERENT SELECTION CATEGORIES
DescriptionThe genetic variability study of Pinus sylvestris trees appurtenant to different selection categories in the plus stand is carried out with ISSR markers. A total of 178 loci were amplified by 6 ISSR – primers and 168 of them were polymorphic. It is detected that the genetic distance between the trees appurtenant to difference selection categories varies from 0,038 to 0,082. Genetic variation parameters of the Pinus sylvestris plus stand are calculated. Shannon’s index (I) was 0,4303, Nei’s gene diversity (H) was 0,2735 and Effective number of alleles (Ne) was 1.4268

Description
One of the ways to save rare species of plants is to create models of natural communities on the grounds of the botanical gardens. In the Botanical Garden of Kuban State University we have created the model of forest communities with the participation of rare and endangered species, and we are still working on creating models of herbaceous communities. We have introduced 18 species of plants of the flora of the Krasnodar region in the forest community and more than 30 species in herbaceous community

ANALYSIS OF SYNANTHROPIC FLORA OF RICE SYSTEMS OF THE KRASNODAR REGION
DescriptionThis article has given the analysis of systematic and ecological structures of synanthropic flora of rice sys-tems of the Krasnodar region. There was shown the relation of plants of aboriginal and adventive frac-tions of flora to different ecological factors. There were studied the timeness of different plant species to elements of the rice system and the degree dependence of their distribution on rice growing tech-nology

SORTIMENT TABLES FOR ESTIMATION OF ARTIFICIAL ORIGIN OAK FORESTS IN THE LOWER VOLGA REGION
DescriptionThe article proposes a system of regression equations for estimating industrial wood size by categories and varieties of commercial trunks of oak plantations in the Lower Volga region. The authors developed a table of logs for the taxation of trees and forest stands of oak

Description
The results of studying the ordinary pine condition in geographical cultures of the Central forest-steppe are cited in the article. The general pattern of the ordinary pine intraspecific variability is represented. The data of origin influence on safety, efficiency, qualitative adjectives is presented. The pattern of ecotypes adaptability to new environment conditions is presented
