Experience on studying of immune genetic properties of esherechious anatoxin is described in the article. There was revealed that new complex of inactivated toxins of intestinal rod is able to stimulate antibodies forming in animal organisms.
DYNAMICS OF CATALASE ACTIVITY IN THE LEAVES OF APPLE TREES UNDER THE INFLUENCE OF FOLIAR FERTILIZING
The research was conducted studying the effect of
various system of foliar fertigation on catalase activity
in the apple orchard with drip irrigation in 2013-2014.
The object of research were apple trees of
Zhigulevskoye variety grafted on rootstock 62-396 in
experimental intensive apple orchard of I.V. Michurin
FSC which had been planted in 2007. During
vegetation, the following indices were determined in
apple tree leaves in dynamics: catalase activity by
gasometrical method of M.I Lishkevich on the 3rd and
5
th day after treatments, the content of nitrogen
(Kjeldahl method), phosphorus (KFK-3), potassium
and calcium (Jenway PFP-7). Data were statistical
processed according to the generally accepted methods
described by B.A. Dospekhov. It has been established
that foliar fertigation increased catalase activity on the
3
rd day after treatment, which then decreases to normal
values. So, treatments acted as a stress factor.
Correlation of catalase activity with nitrogen content in
the leaves increased, and with calcium content
decreased as the number of megafol mixed with
calcium calbit treatments was enlarged. Using tank
mixtures for multiple treatments with combination of
antistress preparations and calcium-containing
agrochemicals allows to moderate significantly the
stress effect of foliar fertilizing on plants
The production of eggs is one of the most important indicators of the productivity of poultry, including chickens The main purpose of breeding chickens in the collections of genetic resources - conservation of genetic diversity. The chickens from the collection of genetic resources it is also possible to receive products, for example, in the form of eggs. The account of the egg productivity of the chickens showed that the intensity of egg production varies among representatives of different directions of productivity. The most stable egg-laying was possessed by chickens of breeds New Hampshire, Black Australian, Dutch white. These breeds are bred as breeds of egg direction of productivity. But they are characterized by long downturns in egg production, lasting more than 7 days. Chickens of meat direction by stable, but low intensity of egg production. All the chickens had a short period For all chickens a short period is characteristic, when the egg-laying is kept at a certain level. It is 30-40 days, after which there is a gradual decrease in this indicator. Such a high level of genetic diversity in egg production in gene pool makes it possible to use this bird as a model object for studying its features
In the article, we have studied the effect of antibiotics on enzyme’s activity of black soil. Introduction of the high doses (600 mg/kg) of antibiotics benzylpenicillin, nystatin) leads to considerable decrease in enzyme’s activity of soils. The class of hydrolyses is most sensi-tive to the action of antibiotics, their activity decreases for 50-70% from control values, the class of oxidore-ductase is least sensitive (10-40%). Antibiotic’s action on enzyme’s pool of soils has the prolonged character
The dynamics of closed wood coniferous and deciduous forest formations for the last 15 years are presented
Under conditions of vegetation experiment at soil artificial chloride salinization the dynamics of accumulation and distribution of sodium, potassium and calcium in organs of rice plants (Oryza sativa L.) have been studied, as well as their correlation with tissue hydration in ontogenesis. The significant restriction of salinization ions transport and accumulation, particularly sodium, in the actively functioning upper leaves and panicles has been observed. Whereas the content of calcium and potassium in the experimental and control plants differed slightly
The article considers the main point of liberal ideology, its spontaneous connection with ideas of Enlightenment, reasons of victory of liberalism over ideological competitors. The factors, which water down the integrity of liberalism in present conditions of the Enlightenment, are analyzed, the main trends of modern modification of liberalism (libertarianism, agonal liberalism, Kantian liberalism) are considered. There were determined the possible perspectives of liberalism as a world-view in limits of which there were stated the strong positions of liberalism as a practical rootedness as well as the high popularity of ideas of Enlightenment in scientific communities
Remineralization of leached chernozem was carried
out by applying such rocks as loess-like loam, shell
limestone, apatite phosphogypsum. We have
revealed that the introduction of species didn’t
change substantially the content of boron during the
growing season. We have also displayed the seasonal
dynamics of macro variants of the experiment and
the increase in the content of food items in the phase
of active growth of winter wheat. Seasonal dynamics
of trace elements is expressed, but can not be
expressed with certain regularity
In the article there were given the results of researches
for 20110–2012 obtained of many years stationary
experience of the chair of general and irrigated land
management of Kuban State Agrarian University on
study of main soil treatment influence and doses of
mineral fertilizers under soy beans on dynamics of
moisture in soil and efficiency of its use by this cultivar.
There was determined that from all studied variants
the ploughing on 20–22 cm led to the higher accumulation
of moisture for autumn-winter period. The
decrease of productive moisture reserves on 6-9 % was
observed on the types with surface treatment and direct
sowing. The increase of soil treatment depth and doses
of mineral fertilizers promoted to the better accessibility
of moisture during vegetation period and correspondently
to their greater expenses. Moreover, there
was revealed the more rational use of water by soy
beans under mouldboard soil treatment and introduction
of mineral fertilizers in the dose of N90P120, it discovers
the high effectiveness of present agricultural
methods. The highest productivity of soy beans in the
experience was achieved by means of ploughing on
20–22 cm and introduction of mineral fertilizers as a
main type of soil treatment
Accounting stands (1959, 1977, 2007) revealed reduction of areas dominated by deciduous species and larch in the State Nature Reserve "Stolby". Area stands of fir and pine increased. Area stands of cedar and spruce didn’t change over the last 50 years. Deciduous stands differs rapid accumulation of stock, but they have productivity lower then conifers. There is a shift in even-aged stands to multiple-aged stands in coniferous formations. They are close to a climax state. Cedars grow on the type of the even-aged stands, because they appeared in the area recently
