DYNAMICS OF RESTORATION OF BIOLOGICAL PROPERTIES OF BLACK SOILS POLLUTED WITH OIL
DescriptionNegative impact of oil on biological properties of soils right after pollution is shown in the article. Eventually, there is their restoration. However, even in some years after pollution, the biological properties of soils aren't restored completely

Description
In the article we have investigated the influence of nickel oxide in the amount of 100, 1000 mg/kg of the soil (1, 10 MPC), combined with the influence of an alternating magnetic field of induction of 50, 100 and 650 µT power frequency of 50 Hz on the biological properties of alkalinity black soil

BIOLOGICAL FEATURES OF THE BLACK SOIL DEPOSITS IN THE BOTANICAL GARDEN OF SFU
DescriptionWe have studied changes in flora, humus content, peroxidase activity and polyphenoloxidase in ordinary black soils in natural succession of different-age deposits. We have also selected stage successions in uneven deposits

Description
This study was aimed on testing of IRAP markers developed at plum on varieties of peach, Russian plum and cherry plum and genotyping of home and foreign varieties of plum, followed by an analysis of the data. During the testing of the markers have been identified as a high level of polymorphism between genotypes of plum and between the studied species. On the basis of the results obtained by genotyping 15 samples of Prunus was built dendrogram. Cluster analysis was divided into 3 groups corresponding varieties of P. persica, P. domestica and a common group for varieties of Russian plum and cherry plum

STRUCTURE OF FORESTS OF PREDKAMJE OF THE REPUBLIC OF TATARSTAN
DescriptionThe article presets results of the studies that reflect the nature of the distribution of forests of Predkamje of the Republic of Tatarstan on the types of forest grown conditions, the predominant tree species, age, site class, completeness and volume of stem wood. It is shown that there are large reserves of increasing productivity of forest stands by optimizing their density and species composition of forests

EFFECTS OF INCREASED WATER TEMPERATURES ON REPRODUCTIVE CHARACTERISTICS OF RAINBOW TROUT FEMALES
DescriptionThe effects of increased water temperatures on the reproductive characteristics of rainbow trout females were studied. It was found, that the increased water temperatures produced negative effects on the gonad maturation and survival of the embryos when acted at the late stages (IV and V) of female gametogenesis, but not at the earlier (III) stage
