Description
The peculiarities of vegetative propagation of ornamental plant Hypericum forrestii (Hypericaceae) by cuttings under conditions of the Black Sea coast of the Krasnodar region have been studied. It has been found that summer cuttings of lignified and semi-lignified propagula are the best for vegetative propagation of Hypericum forrestii

DYNAMICS OF MOUNTAIN FOREST IN RESERVE AREA (“STOLBY” RESERVATION)
DescriptionAccounting stands (1959, 1977, 2007) revealed reduction of areas dominated by deciduous species and larch in the State Nature Reserve "Stolby". Area stands of fir and pine increased. Area stands of cedar and spruce didn’t change over the last 50 years. Deciduous stands differs rapid accumulation of stock, but they have productivity lower then conifers. There is a shift in even-aged stands to multiple-aged stands in coniferous formations. They are close to a climax state. Cedars grow on the type of the even-aged stands, because they appeared in the area recently

Description
The article considers the agro-botanical characteristics of pumpkin annual plants – lagenaria ( Lagenaria siceraria (Molina) Standl.) have been consider in article. The task of the analytical study went in search of communication between anatomic-morphological characteristics of plant and use this in the images, the iconography of the cultural traditions of different nation

Description
In this article there have been given an analysis of a complex of biochemical signs, usual for cold resistant apple, cherry and plum sorts. There have been found the regularities of variability for different complexes of biochemical signs which is similar for all investigated cultures

THE ACCUMULATION OF COPPER AND ZINC COMPOUNDS IN BLACK LEACHED SOIL UNDER TECHNOGENIC POLLUTION
DescriptionThe influence of exogenous form of heavy metals intake on their transformation in the soil is determined during the model experiment. Distinctions in quantity of extracted mobile compounds of heavy metals in the soil depending on a form of addition various connections of Cu and Zn are established. The smallest mobility of Cu and Zn at addition of heavy metal oxides is observed. It is established that Cu accumulates mainly in the fraction connected with organic matter, Zn accumulates in residual fraction and in the fraction connected with ferric oxide and manganese oxide by consecutive fractionation technique

ECOSYSTEM DEGRADATION OF THE LIMESTONE MASSIFS OF WESTERN CAUCASUS AFTER DEFORESTATION
DescriptionSignificant changes in mountain ecosystems occur after deforestation on limestone massifs of the Western Caucasus. Tall-mountain-meadow vegetation with a large variety of species formed at low and medium soil disturbance 3 years after logging. Physical and biological properties of calcareous soils also vary greatly. The values of biological activity decrease at the maximum load is more than 10 times. Biological activity is increased by 20-50% or more cutting stations with low disorders. Biological properties of soils (especially the enzymatic activity) are very sensitive indicators of changes that have occurred as a result of logging. Changes in the activity of soil hydrolases different from changing oxidase activity at different times after logging

STABILITY EVALUATION OF SOUTHERN RUSSIA SOILS TO CHEMICAL POLLUTION
DescriptionWe propose a method of biodiagnostics of soil resistance to chemical pollution and its regulation on the degree of violation of the ecological functions of soil based on the definition of the integral indicator of biological state (IIBS) of the soil. The comparative assessment of the stability of the major soils of the south Russian to chemical pollution are considered in this article
