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 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
This article aims to study the effect of insect pests in oak forests, as well as the impact of the green oak leaf on other types of leaf-eating insects
The article shows the influence of associated species on oak trees in small groups and evaluation of the state of the oak tree category depending on its surrounding
Significant 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
We 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
This article shows how soil contamination with oil leads to a significant decrease in the values of its biological properties. High levels of induction of the alternating magnetic field intensified oil toxic effects
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
In the article we investigated the effect of the bacterial metabolites compositions (Aktoflor and Patogen) on antagonistic activity of L.acidophilus D â„– 75. It was shown the both compositions stimulate integrated antagonistic activity of L.acidophilus D â„– 75 by inducing the synthesis of the bacteriocin and decreasing the proportion of low active clones in the population. We have also shown the advantage of probiotic bacteria metabolites (Aktoflor). The results can be used to enhance the probiotic potential of the bacterial preparations
The article proposes a method for landscape area analysis, which consists of four stages. Technique is proposed as a tool for the practical application of pre-project research materials in the design solutions for landscape areas planning and organization
