The results of the researches of the technology impact of various intensity levels on the productivity of forage crops in the Priazovskaya zone of the Rostov region are given in this article. Economic effective technologies for each crop are identified
An analysis of the state of contamination of rice crops
with red-grained forms was carried out, as well as
impurity was found both in the seed material and in
the soil. It was shown that there is a need to switch to
non-weeding seed growing technology when
conducting elite and reproductive seed production.
Various variants of soil cultivation in combating the
red rice forms are considered, both in the main and in
the pre-sowing treatment. It has been found that after
harvesting rice on heavily foul areas, it is better to
burn straw, and not to carry out autumn tillage of the
soil, the seeds of red-grained forms die mostly when
wintering on the soil surface. The most effective
method of soil cultivation for controlling of red rice
forms in seed crops has been identified, in which the
yield is increased, and the contamination of crops and
the resulting rice grain is significantly reduced. The
work carried out will allow reducing manual labor
costs in the production of seeds, improving their
quality and assortment, speed up variety changing and
variety updating
In this article, we have considered the possibility and the availability of cold plasma technologies application in different branches of industry. We have described the investigations of cold plasma treated water in potato growing technology which will conduct in PetrSU at Agricultural faculty. The basic parameters of the device for water treatment with cold plasma are described. The results of the experimental investigations about cold plasma treated water influence on potato growth and productivity are presented
The introgression of race-specific blast resistance genes Pi-ta, Pi-b, Pi-z into genotype of Russian rice variety has been performed by backcross method with marker control of donor alleles. Plants that demonstrated maximal similarity with recurrent parental form, the short vegetation period and abundant panicle fertility have been picked up from BC3-population.
Marker analysis of developed population revealed the samples carrying introduced target genes in homozygote state
In this article we present information on features of
microcloning in culture of in vitro of perspective for
Eurasia, pink and white-berry table genetic grades of
grapes by I. A. Kostrikin, V. N. Kraynov and V. V.
Zagorulko. Researches were conducted at an input
stage in culture of in vitro of meristems of 0,1-0,2 mm
in size. At the majority of grades and forms, we noted
good regeneration abilities in the conditions of sterile
culture. It is bound to the fact that almost all the
studied grades: Anyuta, Bogatyanovsky, the Princess
Olga, Preobrazhenie, Anniversary of Novocherkassk,
Favor are received from crossing of couple the Mascot
× Sultana-ray grape. And only grades called Libya and
Lowland which showed lower regeneration properties
at stages of proliferation and rooting of shoots are
received from crossing the couple of Flamingo ×
Arkadya and (Talisman x Tomaysky) respectively. At
the same time, the grade of Talisman, being one of the
parents of the majority of the studied grades, showed
stable results at all stages of cultivation
The research purpose was estimate of the red oak
growing suitability in Mari El Republic. To achieve
this goal we investigated experienced 44-year-old red
oak plantation at the Botanical garden-Institute,
determined acorns morphological characteristics of red
and English oaks and seedlings grown from them. The
evaluation of red oak plantings identified excess of
average height and tree diameter in comparison with
English oak, but the sanitary condition of both oaks
forests was weakened due to the influence of the
complex of unfavorable factors. Morphological acorns
evaluation showed that the shape factor of acorns of
English oak is equal to 1.64, while the red oak is 1.1.
Biometrics parameters of red oak bareroote seedlings
in the field were higher than English oak bareroote
seedlings. In greenhouse biometric parameters of red oak container seedlings had not excess. According to
this research, red oak is recommended for use in
landscape construction in Mari El Republic
In the article we consider the influence of agricultural
technologies of cultivation of winter crops on
existence of various forms of heavy metals in an arable
layer of earth in the conditions and their accumulation
in grain production. The gross content of compounds
of copper in an arable layer of black leached soil is
above background values (maximum concentration
limit 1,5-1,7), a share of the fixed connections makes
75 %. The gross content of zinc exceeds background
value for chernozems (1,25 clark). The correlation of
the water mode of the soil and the content of mobile
compounds of heavy metals in an arable layer - a
straight line for Cu and the return for Mn , Pb, Cd and
Co. Supplement of an arable layer of earth with mobile
forms of copper, zinc and cobalt low, manganese -
corresponds to the average level. Speaking of the
degree of actual mobility the studied elements settle
down in sequence: Cd> Mn> Co> Pb> Zn> Cu.
Degree of potential availability decreases among:
Zn> Mn>Pb> Co> Cu. The existence of Mn,
Cu, Zn and Co in grain of wheat is lower than
maximum concentration limit, and accumulation of
Pb and Cd is higher than maximum concentration limit
in grain production for baby food for 10-15 %, that
increases individual risk of death to the maximum
permissible level
Correlation of finished and meat qualities of swine with biochemical and cytochemical indices of blood with the aim of selection of true tests for earlier estimation of productive qualities of animals are carried out and analyzing
Results of the fifth International Conference
(KubSAU,2007) on problems of vintage,
characteristics and storage of perishing wild
and native grape of the North Caucasus and
the Black Sea area regions are dealt with
in the review article. Results of the work of Eurasian countries scientists for the last two years fulfilling
the project of International institute of genetic plant resources Biodiversity International have been cited.
In particular, assessment of wild grape in the places of its initial origin was carried out, world gene pool was enriched on three hundred patterns, methods of molecular marking of grape genotypes and ampelographic screening of two subspecies Vitis Vinifera L. were improved, international data bank was created and variant of regional ampelography was written.
The article shows the results of years of research, which showed that the intermediate culture - is an important factor in the impact of increasing the fertility of meadow black soils, meadow (rice) soils perform environmental, agronomical and soil protection roles,
as well as they are involved in the biological cycle of nutrients
