NETSUKE AS A RESOURCE OF INFORMATION ABOUT SPECIES DIVERSITY OF LAGENARIA SICERARIA (MOLINA) STANDL
DescriptionIn the article, with a descriptive method and a method of analysis and synthesis, we have conducted a study of species diversity of Lagenaria on the basis of a miniature sculpture of netsuke. In Japan and China, in the period from the 17th to the 20th century, the most common was 9 species. The biological peculiarities of some rare species of lagenaria has been described

CHANGES IN BIOLOGICAL ACTIVITY OF BROWN FOREST SOILS UNDER AGRICULTURAL USE
DescriptionAgricultural use leads to a significant transformation of soils. The first to use the soil for cultivation react most sensitive biological indicators. The purpose of the study - to establish the effect of using the brown forest soils for planting apple orchards for their biological activity, in particular on the humus content, enzyme activity (catalase and dehydrogenase). For the control, we have selected forest area adjacent to arable land. Because of violations of the natural vegetation, there are changes in hydrothermal conditions of the soil. Humidity soil plowed off under forest, while temperatures gets considerably higher. Plowing, compared with the control, revealed significant loss of humus (50%) in the upper most disturbed horizons. In the lower horizons of the values of this index were quite low (1.5%) on all sections of the test. The decline in humus content, as well as overheating and draining soil tillage results in a change of enzymatic activity not only in the surface layers, but also in the whole profile. Due to the movement of the most favorable hydrothermal conditions in the underlying horizons, an increase of enzyme activity over control values in the deeper layers of the soil. The article shows a possibility of the use of biological indicators as indicators of changes in the brown forest soils as a result of agricultural use

Description
The article presents the ecological characteristics of soil types and forest cover of the Red October forestry of the State Unitary Enterprise of the Republic of Adygea. We have defined their relationship and the division into groups of forestry and environmental values. A complex combination of bioclimatic factors, parent rocks and topography has led to a large diversity of soil cover. We have revealed that different soils have different degrees of erosion on sloping hillsides, ravines, and steep slopes are dominated by strongly eroded soils. The most common form of physical degradation of soils of the red October experienced forestry is seal root layer observed on heavily used areas and pastures. Also, we found that poorly structured soils containing little humus are prone to compaction. Methods of rooting out areas after clear cutting of forests lead to secondary soil degradation. It especially enhanced if, at the moment of stressing, the soil is in the waterlogged condition. Therefore, at reforestation we should use different reclamation processing. And this leads to the difficulty of their use in reforestation. It is established that intensive anthropogenic activity leads to degradation of soil and forest cover of the study area

60 YEARS IN THE RANKS: FEATURES OF MOLECULAR BIOLOGY OF BEZOSTAYA 1 WINTER WHEAT VARIETY
DescriptionThis review is devoted to the 60 anniversary of the winter wheat variety (Triticum aestivum L.) Bezostaya 1 – a masterpiece of world selection. This variety played a great role in increasing total grain yields in the Kuban Region. It also was an important gene source for Russian and world breeding. This variety has initiated and was for many years a party to research molecular biological mechanisms of wheat frost resistance formation. The article summarizes data about the peculiarities of functioning of protein-synthesizing system it sprouts (coleoptilies) under the influence of hardening temperature (4oC): translational activity in vitro, poliribosomts, degree of polyadenilation and stability of total mRNA and specific mRNA translational elongation factor α subunit 1 (eEF-1 α). The in vitro (ommp) system, which adequately characterizes the relative mRNA stability in vivo was used for these measurements. The effects of cooling and light on mRNA stability were shown to be cultivar-specific. The hardiness of winter wheat has a positive relationship with the amount of RNA and DNA, and a negative correlation with the amount of magnesium cations in mature grain that can serve as a simple marker of frost resistance. The main feature of the variety Bezostaya 1 is high content of magnesium ions (Mg++) in RNA molecules and relatively low variation of Mg++-depending molecularphysiological responses for different environmental conditions. The knowledge gained in the study of variety of Bezostaya 1 contributes to the understanding of molecular biological processes that underlie the selection and determining its future success
