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
The article presents a biological characteristic of
burbots in the waters of Yakutia. We discuss the most
essential features of the ecology of this fish
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
The article presents the results of the studies on the
variability of morphological traits of the
cenopopulations of Allium prostratum, Allium
ramosum on the natural territory of the Yakutsk
Botanical Garden and in cultura. We have performed
researches of biometric parameters, which revealed the
structural features of the plant and the nature of the
variability of their parts. The article also gives an
estimation of coenopopulations vitality
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 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
Humpback whitefish - Coregonus lavaretus pidschian
(Gmelin, 1788), is spread in Siberia, in the Kara,
Laptev and East Siberian seas and in the lakes of the
Arctic and Subarctic. Objective: To assess the status of
fish in the waters of Yakutia, to make ecological
forecasts and determine the possibility and prospect of
economic use of whitefish, as a fish-breeding material
in the present conditions. Methods: The analysis was
carried out on the fresh material as described
I.Pravdina (1966), taking into account the
recommendations of Y. Reshetnikov (1980).
Collection and processing of materials were carried out
in 1969-2015 by standard methods. Results. Reaching
sexual maturity at the sixth (in weight - the eighth and
ninth) year of life, whitefish begin to move to the main
breeding groundsin the early fall. Absolute fecundity
of eggs 2500-140000. Spawning is common in late
September-early October. The food spectrum usually
consists of the following objects: chironomid larvae,
plants, mollusks, fish eggs and copepods. By the
nature of power - benthophage, but often becomes
planktonic organisms. Conclusions. Important food
fish, but its reserves significantly reducedunder the
influence of anthropogenic factors in recent years. The
catch of whitefish can be increased as a result of the
development of aquaculture
Numerous revealed negative impacts of the diamond
industry and Vilyuiskaya HPP on the aquatic
environment and biological objects are more expressed
in the change of the hydrochemical regime in water
basin of Viluy and as its consequence - in violation of
the structural and functional nature of the components
of aquatic biota; in the change of he average biomass
and abundance of planktonic populations
(phytoplankton and zooplankton) and benthic
organisms, and in general - in the change of the flow
energy in an aquatic ecosystem
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
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 %
