THE CURRENT STATE OF PIKES IN YAKUTIA WATERS

abstract 1191605029 issue 119 pp. 415 – 425 31.05.2016 ru 455
Pike inhabits almost all the rivers of the Yakutia system. It is more widespread in the lakes of YanoIndigirka and Kolyma lowlands. Objective: To provide a modern assessment of fish in the main model reservoirs, create an ecological prognosis and the possibility of their use in modern conditions. Methods. The material was collected in the conditions of anthropogenic pollution. Full general biological analysis was conducted for the fish. Cruise studies were conducted covering the northern territories - r. Anabar, Olenek, Lena, Yana, Indigirka, Kolyma and Chrome, as well as Vilyuy Dam, from 1969 to 2016. We used the standard ichthyologic methods of selection and processing of the collected material. Results. Because of climate warming, there were reported pike approaches in the lower reaches of the river Lena, Yana and Kolyma. Maximum dimensions were noted earlier in the lower reaches of the river Lena, where the maximum weight of pike was 18 kg. The fecundity of 16-211 thousand eggs. It was revealed, that the catch was better for young pike. Conclusions. Stocks of pike are in satisfactory condition, and its reserves are proposed to be increased, at the expense of unused areas (lakes Kolymo- Indigirka lowland) up to 220 m. It is proposed as a fish-breeding facility in Yakutia reservoirs

FORMATION OF SOILS STUDY AND THEIR FERTILITY; A HISTORICAL EXPERIENCE OF SOIL CLASSIFICATION

abstract 1191605043 issue 119 pp. 588 – 605 31.05.2016 ru 609
The roots of scientific knowledge on soil go into antiquity and are connected with the development of land management. A human had knowledge about soil as a friable layer of Earth, which was a subject o land management treatment until the time there were occurred the problems of shortage of arable lands, hunger and decrease of fertility, which caused the necessity of obtaining of more produce with less arable lands. The development of soil science was required for solving of these practical tasks. In postwar period there were carried out the large researches in the field of plant nutrition and application of fertilizers. For this period the active study of organic properties of soil occurred. The Dokuchaev’s study on genetic types of soil was the tuning point in the development of problems of soil classification. The further development of problems of soil classification were made on the basis of set genetic positions, thus the various approaches lighting the different parties of a classification problem took place. The soil fertility in force of its important functions for a long time is not only as an agronomic category but also as a social, economic, philosophic, and at the last time – ecological one. The modern understanding of function of fertility is reached with the help of mathematical modeling. First, it is necessary clearly to present the aggregate factors of fertility and their interaction between them and external factors

60 YEARS IN THE RANKS: FEATURES OF MOLECULAR BIOLOGY OF BEZOSTAYA 1 WINTER WHEAT VARIETY

abstract 1181604035 issue 118 pp. 627 – 657 29.04.2016 ru 1198
This 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

THE INFLUENCE OF POLYMERIC GROWTH REGULATORS ON MORPHOLOGICAL AND PHYSIOLOGICAL PARAMETERS OF RICE IN SALINE CONDITIONS

abstract 1181604065 issue 118 pp. 1061 – 1074 29.04.2016 ru 992
The article studies the influence of polymeric in the form of formers and growth regulators on the growth and development of rice plants when grown in saline conditions. We controlled the effect of salinity on grows regulators and vigor, seed germination, root and shoot weight, the content of photosynthetic pigments parameters, induction curves of delayed fluorescence, the indicators of structure of harvest, grain yield. It was found, that pre-sowing seed soaking in solutions of polymer grows regulators has a stimulating effect on the growth and development of rice plants in the early stages: we significantly increased germination and emergence, dry weight of root and shoot compared to control. At different stages of ontogeny rice, the absolute content of pigments in the leaves and the relationship between the individual variants change. The absolute content of pigments in leaves and their relationship between experiences at different stages of ontogeny change. In the period of intensive vegetative growth from seedling stage the content of total chlorophyll is maximum, and by the end of the growing season it decreases. It can be assumed that the salinity of the substrate significantly reduces the productivity of photosynthesis in young plants, possibly due to imbalance of ions in the cell, the older it gets – the weaker the phenomenon is and even becomes reversed. The second maximum IR ZF increases during the growing season from germination to flowering, then decreases to the beginning of ripening in all embodiments. The same dynamics is characteristic of the magnitude of the proton gradient in the membranes of chloroplasts tylakoids. Salt protection effect of growth regulators on grain yield is significant on both backgrounds of mineral nutrition

THE EFFICACY OF USING PHOSPHATE SOLUBILIZING MICROORGANISMS IN GRANULAR BIOFERTILIZERS WITH PHOSPHATE ORE

abstract 1171603014 issue 117 pp. 254 – 271 31.03.2016 ru 754
Two granular formulations of phosphorus biofertilizers combining rock phosphate and two highly active phosphate solubilizing strains: Acinetobacter species 305 and Pseudomonas species 181а have been investigated. Granules of about 3 mm in size were obtained by contact-convective drying of a mixture of ground ore, concentrated biomass of two different strains, starch and glucose. Micro granules with size of 0.1- 0.5 mm were obtained by spray drying the biomass of two different strains and application of dried cells on the particles of the ground ore. Starch was used as a binder. In the model liquid medium it was shown that the microorganisms have retained the ability to solubilize mineral phosphates in granular formulations prepared. In laboratory pot trial on marigold (Tagetes patula) it was demonstrated that both formulations of biofertilizer increased the dry weight of the plants to the same level as that of chemical fertilizer - double superphosphate, but were inferior in the concentration of phosphorus in plants. Both formulations exceeded the effectiveness of rock phosphate and biomass used as biofertilizers both separately and jointly. No significant differences were noted between the two strains and the two granular formulations both for plant dry weight, and the content of phosphorus therein. Both granular formulations of biofertilizer retained their structure and avoided aggregating over a year of storage at 4 oC. The average persistence of living cells in the microbeads was about 1.5%, in granules - 32 %
