We have presented information about species diversity
of the coastal zoobenthos in some of Karasun lakes,
Krasnodar. We have shown methodology information
and reported the research area. We have made a
taxonomic analysis. The biomass and the quantity of
the main zoobenthos groups were calculated. Based on
the two main fodder objects - Olygochaeta and
Chironomidae and the P/B coefficient, there was
calculated zoobenthos production of the studied lakes.
The potential fish capacity was defined
In this article we consider application of the automated systemic and cognitive analysis (ASK-analysis), its mathematical model – a systemic information theory and the program tools realizing them – the intellectual Eidos system, for input (digitization) of images from graphic files, synthesis of the generalized images of classes, their abstraction, classification of the generalized images of classes (clusters and constructs), comparison of concrete images with the generalized images (identification) of classes, comparisons of classes with each other and creations of the generalized images of genus of ground beetles on the basis of images of the types. The new approach to digitization of images of ground beetles based on use of a polar frame, the center of weight of the image and its external contour is offered. Before digitization of images, their transformations standardizing the provision of images, their sizes and an angle of rotation can be applied. Therefore, the results of digitization and the ASK-analysis of images can be invariant (are independent) concerning their situation, the sizes and turn. There is a successful experience of the solution of similar tasks in other subject domains. This article can be considered as a continuation of series of the works devoted to application of the automated systemic and cognitive analysis (ASK-analysis) and its program tools – the Eidos system
The article presents data on the growth of an
assimilation apparatus of Scots pine, silver birch and
pedunculate oak in the conditions of the Lipetsk
industrial center. It is established that the growth
dynamics of annual and biennial needles of Scots pine
under pollution is higher compared to the control,
while absolute values of length and mass of needles
less. Starting from the second year, in the conditions of
contamination noted stunted pine needle growth,
which increases by the third year. It is shown that the
linear dimensions of the lamina of birch in the
conditions of pollution are not changing much
compared to the control, whereas the linear dimensions
of the lamina of pedunculate oak in the conditions of
pollution is less than the control

In the article we present the results of comparative researches of herbaceous covering of plant communities in the alpine zone of the Republic of Dagestan on the example of Dido- depression. The plant covering of the investigated region differs in extraordinary variety. The general regularity of plant distribution is vertical zones. There were made 6 ground profiles at different elevations from 1450m to the alpine zone at 2500m above sea level. Variety of phytocenoses is connected as with changes of ground conditions, so with environmental conditions. We have researched and identified the types of grounds with laying of grounds profiles on the vertical zonality. There we studied the specific composition of herbaceous plants on the examined ground and given names to plant communities. The studying phytocenosis are analyzed by productivity of functional groups. We have shown the share of each species and their abundance. Of all plant communities, the mass of herb differ dominates. The composition of plant communities is analyzed, depending on high-altitude grades and degree of anthropogenic load influence
For the conservation of biodiversity, this study of
patterns of biological processes and phases in the
development of Convallaria majalis L. that are
repeated annually becomes actual. In the article, we
have presented an analysis of five years of
observations of the rhythm of the development of
Convallaria majalis L. in the conditions of the middle
Don. There were allocated phenological phases of lily
of the valley: vegetative (beginning of sprout growth,
deploying of leaves), bud formation, flowering
(disclosure of the first flower, mass blossoming, the
withering of separate flowers, the ending of
flowering), fruitage (the beginning of fruit setting,
mass of fruit setting, mass ripening of fruits), the end
of the vegetation (appearance of the first changes in
color of leaves, the complete drying). We have defined
daily average temperature and the appropriate amount
of positive temperatures for the passage of various
phases of development Convallaria majalis L. By the
results of two growing seasons, the optimal daily
average temperature for the flowering period is 14,3 °
C (the sum of average daily temperatures 161,3-204,
0С) - until 9-15 days. At higher daily air temperatures
flowering begins at lower amount of positive and
effective temperatures after 40-45 days after the start
of the vegetation. At lower daily air temperatures
flowering is longer than at higher. In the conditions of
the middle Don there were allocated some examples of
Convallaria majalis L. which bloom two years in a
row
Tomato is one of the most popular vegetables in Kuban. Every year, the area under this crop in the region occupies more than 11 thousand ha. Currently the State Register of Breeding Achievements approved for use in Krasnodar region, includes more than 90 tomato varieties and hybrids, however, the need for new, more productive varieties is not reduced. The important task of breeding is development of varieties and F1 hybrids with stable realization of the potential, with high level of yield ability, resistance to adverse environmental factors. In the southern regions of Russia for tomatoes, especially during flowering and fruit ripening, the most unfavorable abiotic environmental factors are excessive heat (air temperature 35 - 45 ° C or higher) and high solar radiation. Adverse temperature conditions often act as a deterrent in obtaining high yields, due to the flowers and fruits drop. The article presents the results of breeding activities of the last ten years (2007 - 2016) on development of new tomato varieties and F1 hybrids for different purposes As a result of studies there were developed four tomato varieties and one F1 hybrid that meet the requirements of production and are adapted to abiotic conditions of cultivation in open field in Kuban
Questions of microbial plant protection become more
relevant. The use of microorganisms can solve the following
problems: biologization of agriculture and sanitation
of soil. Application of various physical factors
affecting the microorganisms reduces their number.
This influences the efficiency of their use. This article
gives examples of the application of pressure in the
biotechnological process of microbial preparations and
their use in the process of spraying. The effect of pressure
on nonspore bacteria - Azotobacter chroococcum,
spore-forming bacteria - Bacillus megatherium and fungi
- Trichoderma viride has been presented in this article.
These microorganisms are used in the tank medium
for protecting plants against diseases and pests developed
by Ltd. "Kuban agrotehnoloogy" of Kuban State
Agrarian University. Efficiency is the simultaneous
application of tank medium of microorganisms with
herbicide. It was found that the application of the tank
medium of microorganisms for spraying is necessary to
limit the pressure of 4.5 atm. Тhe use of higher spraying
modes effects on reducing the number of viable bacteria.
This fact has not been checked against fungi
In the presented study, we have performed genotyping
of modern Russian rice cultivars using microsatellite
DNA-markers. The markers showed different level of
allelic polymorphism: from 2 to 8 alleles per locus. For
all studied cultivars,unique DNA-fingerprints were
obtained
The work was carried out in the scientific-research
laboratory of the chair of Biotechnology, Biochemistry
and Biophysics of Kuban SAU, the aim of which is the
search of optimal conditions of obtaining the
hydrolyzates of lactic acid bacteria by thermoacid and
enzymatic ways. The pure cultures of microflora of
gastrointestinal tract of quails − Lactobacillus agilis,
Lactobacillus intermedius and Lactobacillus salivarius
were the object of researches. Under conducting the
thermal acid hydrolysis there were used the same
correlations of bacterial mass and water as well as
procedures of clearing of hydrolyzates. The variable
conditions were рН, temperature and time of hydrolysis.
When carrying out the enzymatic hydrolysis in this
study there was used the enzyme from the group of
muramidase lysozyme. The amount of enzymes and
time of carried out hydrolysis were the variable
conditions under obtaining the enzymatic
hydrolyzates. In the process of researches there were
studied: qualitative content of total protein, peptides
with М.м. < 1500, protein and peptides with M.m. >
1500, aminoacids and as well as GMDP
(glucosaminilmuramilpentapeptide). On the basis of
carried out experiments there was stated that according
to all components of biologically active substances the
thermal acid way is more effective than enzymatic. The maximum accumulation of BAA in hydrolyzates
by different ways was revealed at destruction of cells
Lb. intermedius. Content of GMDP in thermal acid
hydrolyzate was higher than in enzymatic on
