Description
The article considers the new method for recovery of P. arbelaeziion intact material on the basis of grafting into endogenous pathogens resistant Passiflora species in vivo. The influence of the explants origin depending on the stock of intact plants on the development of regenerated P. arbelaezii under in vitro condition is examined

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

THE ROLE OF SCIENTIFIC ILLUSTRATION IN THE HISTORY OF BIOLOGY
DescriptionIllustration is an important part of scientific work and educational process. They help us understand studying material and see the different connection among things. The different types of illustration were analyzed and we also demonstrated illustrations in scientific world, education materials and the role of abstraction in scientific illustration

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
During cultivation in the glucose-mineral medium, Escherichia coli M-17, O75, № 14 and VL 613 and Salmonella enteritidis excrete amino acids, their composition and dynamics depend on the species and the strain identity. The total concentration of the ami-no acids for probiotic strains was higher than oppor-tunistic. Comparative analysis of the amino acids to their ability to influence the growth of bacteria, sug-gests that amino acids are carry out certain regulatory functions

INFLUENCE OF THE NEW RACES OF YEASTS ON THE CHEMICAL COMPOSITION OF THE WHITE TABLE FAULTS
DescriptionThe influence is shown for the race of yeasts to the dynamics of the fermentation of grape must, the composition of organic acids and aromatic of components. The races, which ensure obtaining high-quality winemakings material are presented

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
