ENZYME ACTIVITY OF SEVERAL SOILS OF THE CRIMEA
DescriptionThe article considers the enzymatic activity and some other ecological and biological properties of zonal soils of the Crimea (cambisol, Chromic cambisol, different subtypes of chernozems). We have revealed significant differences in catalase, dehydrogenase, polyphenol oxidase, peroxidase, invertase for soils of the Crimea, which can not be explained only by the content of soil organic matter. Despite the low humus content of the soil, some have a high level of some enzymes. The level of enzyme activity depends on the reaction medium, the content of carbonate and other soil properties. We have also revealed that the agricultural use of brown soils under vineyards leads to a significant change in their properties and enzymatic activity

FENOLOGICAL VARIABILITY OF TREES AND SHRUBS IN TOMSK
DescriptionThe analysis of phenological phenomena of 9 tree and shrub species and longevity of their vegetation activity was made in Tomsk (southeastern West Siberian Plain). Since 1969 until 2013 the start of the phenological phenomena in the trees and shrubs became to be earlier and the end did to be later. Trends of the start of birch juice moving and flowering is higher (–2.5–3.4 days/decade) than trends of leave appearance, yellowing and falling (+2.5–1.3 days/decade) in the trees and shrubs. Dates of the start of the phonological stages and the sums of accumulated positive temperatures high correlate between each other. The period of their general vegetation activity increased by 20 days and active vegetation activity did by 7 days

FASCIATION IN NATURE AND IN EXPERIMENTS
DescriptionThe phenomenon of fasciation on the example of higher plants was considered. The effect of fasciation on the various particularities of plants has been shown. The numerous examples of the different groups of plants with fasciation bodies are given. We have demonstrated that the phenomenon of fasciation is more common for cultivated plants than for wild. In most cases, fasciation is considered as an exceptional phenomenon. A number of authors have distinguished fasciation to inheritable and non-inheritable. The first is caused by internal reasons. The second is the influence of external factors such as insect damage, injury, weather conditions. The number of regularities was installed: reproductive bodies of plants fasciationing more often; thermophilic forms are more likely to be fasciation. The images of different cultures with fasciation parts are given. We discuss using the introduction of the term ”connаtions” as morphological abnormalities. Fasciation can be considered as a marker trait for the cause of this phenomenon with violation of ecological situation. The plants with morphosis, including fasciation of the certain parts of bodies, can act as indicators of environmental pollution. The study of the phenomenon of fasciation in higher plants can be regarded as a method of breeding for large fruit size. From one side, to establish the adaptation abilities of newly created genotypes. Thus, the phenomenon of fasciation has affected many areas of science. On the other side, it is proof of the violations caused by environmental factors. On the other hand, it is hereditary reasons, and can also serve as a model for studying morphogenesis

BLACK SOIL RESISTANCE TO COMBINED OIL AND ELECTROMAGNETIC POLLUTION
DescriptionThis 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

Description
Due to the wide spread of winter barley varieties with different Phytopathologic characteristics, a serious threat to the crop is dwarf rust caused by a pathogenic fungi of the Puccinia. The article presents the results of phytosanitary studies conducted in different agroclimatic zones of the North Caucasus region for the period from 2013 to 2015. Electronic maps of levels of development and distribution of dwarf rust are based on phytosanitary inspection. On the experimental field called «Kuban» as well as rust nursery of VNIIBZR we have performed an immunological evaluation of the sustainability of winter barley accessions to the pathogen of the dwarf rust on natural and artificial infectious backgrounds in the period from 2013 to 2015. The article reflects the objective characteristics of varieties and lines of winter barley with a relative stability to the North Caucasian population Puccinia hordei. The most promising varieties and lines of winter barley of the KubGAU breeding were selected during operation. These varieties and lines are highly resistant to rust and dwarf, they also have other valuable features. The article presents information on the best yield varieties and lines of winter barley as well as on gross yield and sowing area

Description
The article presents materials about selection and optimization of the nutrient medium for cultivation of Propionibacterium shermanii. We have shown a high positive effect expressed in the intensive growth of microorganisms of Propionibacterium shermanii on optimized medium with the juice from the tomatoes, as well as replacement of glucose on corn extract, which allows concluding that these components have a positive impact on the accumulation of biomass of Propionibacterium shermanii
