The impact of anthropogenic pollution on soil
phytotoxity and on triticale plants in Vladikavkaz
suburb was investigated in the work. The objects of
the study were sod-gley leached soils and different
varieties of triticale plants. The research was
conducted in 2010-2011 at the Department of Biology
of Gorsky State Agrarian University. The article gives
data on microelements content in soils and plants
within the range of influence of Vladikavkaz industrial
enterprises. There was a marked change of
miroelements’ mobility in soil and activity of their
penetration into plants during fertilization. The sort
characteristics of microelements’ accumulation in
vegetative mass of triticale were researched. The
conducted research is informative for soil and plant
condition monitoring in anthropogenically polluted
environment. The work indicates the increasing danger
of microelements (including heavy metals)
accumulation in soil and their inclusion in biological
cycle in concentration that is too toxic for plants,
animals and people during the usage of fertilizers,
especially their high doses. The most dangerous
among heavy metals are mercury, cadmium and lead.
We used MPC rate of excess to estimate the content of
these metals. The results of the research can be used in
soil and cereal plant condition monitoring and
diagnosis and in development of regional
environmental regulation
This article presents the studying results of new premixes of domestic production using efficiency based on processed products, in particular - oil cakes. The research was carried out in the conditions of the second-order pedigree reproductor in LLC "Svetly" in the Svetloyarsky district of the Volgograd region in the period from 2015 to 2017. During the scientific and economic experience, the authors revealed the new fodder additives positive influence on the laying hens’ egg productivity, on the eggs morphological and incubation rates and on the got young birds. The use of premixes in layer diet, which included the fodder concentrate from the plant raw material "Sarepta" and Camelina seed oil cake, contributed to the increase in the hens laying capacity, in general, the group received in 249 and 310 pieces more than in the control one. The egg average weight from the chickens of the control group was 60.89 g; from the first experimental it was 61.33 g; from the second experimental it was 61.39 g, which was higher than in the control one, respectively, by 0.44 g and 0.50 g. While the hatching eggs morphological indices analysis, it was revealed that all parameters are within the permissible limits of the physiological norm. Fertilization of eggs in the control group was at the level of 89.33%, which is lower than in the experimental groups. As a whole, the eggs' production in groups was 20.00% in the control, 17.33% in the 1st group, and 16.00% in the 2nd test group
One of the prospect directions in new sunflower
hybrid development is cold resistance breeding in
the emergency stage. Sunflower hybrids with
uniform emergency and high rate growth under the
low temperature conditions could allow to
introduce sunflower in the new regions of our
country and so to increase sunflower acreage. The
aim of our work was to screen all sunflower
available samples for growth rate under the low
temperature and to select the best lines and initial
material for future breeding. 140 sunflower lines of
VNIIMK breeding and hybrid populations on their
base were used as a material. Seeds of every sample
were incubated during the 10 days in the thermostat
under 100 С. Seed germination was evaluated for
the each sample along with the seedling size. As a
result the most prospective samples were selected
for the future breeding work. On the second stage
of the experiment one selected population was
evaluated on the Breeding station of Vavilov’s AllRussian
Research Institute of Plant Industry in the
city of Pushkin (Leningrad region). Seeds from the
best plants were obtained in this place and will be
used for the new lines development.
So the effectiveness of selection of sunflower
samples for growth rate under the low temperature
was verified and this method could be used to
introduce sunflower in the new regions of our
country with more severe climatic conditions
Early-ripening white cabbage has a special place
among the vegetables cultivated in Kuban region. It
opens the pipeline of vegetables from the open
ground and is supplied to other regions at a time
when shortage of vegetables of domestic production
is felt the most. Modern producer requirements to
domestic hybrids are the highest - product quality,
uniformity and productivity should not concede to
foreign analogues. Ways to improve the quality of
early ripening hybrids: development of lines based on
modern foreign hybrids, high uniformity of lines by
morphological and economic traits. Development of
male sterile lines and dihaploid lines in culture in
vitro can more successfully solve the problem of
quality of early ripening hybrids. The use of the
above methods and approaches helped develop series
of inbred lines - gene sources for complex agronomic
traits. On the vase of obtained lines promising earlyripening
hybrids were developed. One of the hybrids,
Ritsa F1, entered the State register of breeding
achievements. Advantages of the hybrid: earliness,
uniformity and high marketability of heads, high
productivity. According to results of contest trial new
hybrid Milana F1 is passed for State trial, this hybrid
has high productivity potential for growing in sale
cropping. Both hybrids were produced with the
participation of male sterile line Dt46f, resistant to
fusarium. High quality seeds of these hybrids were
produced in a greenhouse in direct crop for a wide
industrial and environmental testing
Feijoa crop is valuable due to the complex of useful
traits (high frost resistance, big yield, ornamental
value and long profitable period). These fruits have
delicate flavor, nutritional and dietary properties. The
fruits are juicy with a pleasant, gentle, refreshing
sweet and sour taste, specific strawberry-pineapple
flavor and contain significant quantities of important
substances for the human body. Pectin (up to 2.5%),
sugars (6-14%), proteins, vitamins, organic acids,
mineral salts, etc. are among them. However, the
challenge of its cultivation is the lack of cultivars and
plantations are represented by a mixture of hybrids
originated from free pollination, and characterized by
a great variety in biological and morphological traits,
differing not only in yield, but in size, shape and
yield period. In this connection, the breeders faced
the objective to create new cultivars of feijoa, using
classical and modern breeding methods and available
genetic resources for commercial gardening and
production. Development of the core hybrid diversity
material and selection of promising forms are the
most important stages of the breeding process,
providing success of further breeding programs. The
breeding of varieties and forms for crossings was
carried out according to the principle of combining
the desirable traits of the obtained offspring. There
are direct and reverse crosses in six combinations
('Dachnaya' x 'Superba', 'September' x 'Superba',
'Dagomysskaya' x 'Superba', 'Superba' x 'Dachnaya',
'Superba' x 'September', Superba ; X 'Dachnaya'). The
viability of the pollen was evaluated prior to
pollination, by germination on a nutrient medium -
1% agar-agar + 15% sucrose. The degree of fertility
varied year by year: in 2015 - 60-62%, and in 2016 -
68-77-88%. The best crossing combinations were
established 'September' x 'Superba' and the 'Superba'
x 'Dagomyskaya for the creation of the hybrid
genepool of Feijoa sellowiana. A high percentage of germination of the feijoa seeds was noted in
combinations of 'Dagomyskaya' x 'Superba' (74%)
and 'Superba' x 'Dagomysskaya' (70%).
Using of seedling method for growing early potatoes
accelerates the starting processes of growth and
development of plants, and the application of
temporary covers of the nonwoven covering materials
protects the landing from sudden temperature changes
and relapsing frost. To receive seedlings of early
potatoes we used standard seed tubers of 60-80 g
weigh of the following varieties: Agata, Red Scarlett,
Kislovodskiy, Vershininskiy and Sheri. By the time of
planting in the ground, depending on the varieties, the
height of seedling was from 13 to 26 cm, the number
of leaves - 7-10 pieces. Conducting of trial unearthing
of potato showed that on 45 days after transplanting
into the ground (the second decade of May), it is
possible to receive up to 10, 5-11, 4 t/ha (Agata and
Red Scarlett varieties). On 55 days (the third decade of
May), the yield reached 26, 4 t/ha of standard tubers,
and in the first decade of June the yield was from 26, 4
to 50, 6 t/ha. The maximum yield of standard tubers of
50, 6 t/ha was obtained by lifting on 65 days with the
Red Scarlett variety. In the terms of the Astrakhan
region the growing of early potato by seedling method
with using of temporary cover allows to receive the
ultra-early harvest of marketable tubers in the II-III
decade of May
The biotechnology (year - round utilization of livestock and spirit wastages) was developed for the protection of farmlands and water objects. Technology of processing of organic wastages by means of earthworms (vermicomposting) gives the chance to use wastages of livestock complexes, to make a sewage disposal at minimum energy consumption. In the field experiment which was made in the training farm called "Kuban" for the detailed studying of influence of the held events there were put the platforms. The technique of probability of estimation of ameliorative condition of an irrigated field is given in the article. The nonparametric statistical assessment of degree of soil compliance to the normative conditions is defined
The article presents results of the evaluation of the
physiological aspects of growth and fruiting of peach
on clonal rootstock VVA-1, depending on the layout
of the trees. It was found that when forming a spindleshaped
crown, the most productive planting scheme is
5,0Ñ…1,5 m, at which the most optimized physiological
processes were proved
The modern cattle breeding in Russia is
characterized by dynamic development, development
of intensive technologies, increase in production, but
at the same time, there are problems of increase in
production of milk due to increase of dairy efficiency
of cows at the most effective manifestation of the
available level of their genetic potential. For the
solution of this problem, i.e. for genetic
improvement of dairy cattle, creation of new breeds,
intra pedigree or zone types, more than 100 thousand
of bulls with high genetics, and also 430 thousand
heifers were delivered to Russia for the last 10 years.
In this regard, the purpose of our researches was to
study the level of genetic potential of dairy cows in
breeding farms of "Nasha Rodina" of Gulkevichsky
region, Vasyurinsky milk farm of Dinsky region, the
Firm «Agrocomplex» of Vyselkovskiy region
(Gazyrskoye enterprise), "Urozhay" of Kanevskoy
region from 2000 to 2014, by using bulls of
Golshtinsky breed. Researches have shown that in
farms of the Krasnodar region producers with the
high level of potential from 10791,0 kg to 12045 kg
on milk were yield used on a breeding uterine
livestock; from 4,22 to 4,40% of fat; from 3,32 to
3,49% of protein in milk. As a result the level of
potential of daughters of bulls and cows in herds of
farms was from 7774 to 9144 kg of milk; from 3,89
to 4,05% of fat; from 3,26 to 3,67% of protein in
milk. However, genetic potential of new generation
of animals is shown not completely. It is influenced
by partial compliance of the created technological
conditions of biology of animals, and indicators of
breeding value of producers, with their prepatent
indicators. Calculations of breeding value indexes of
bulls – fathers of cows in the herd of "Urozhay" have
shown that each bull has its breeding value, an
ability to transfer the qualities to posterity. Bulls of
Golshtinsky breed of red – motley color ( Pan 2037
and Tulup 78160689), by results of comparison of
milk yields of daughters, mothers and
contemporaries, had negative prepatent indexes of
milk yield and milk protein content (according to
F.F. Eysper and V. Sidorova). The data confirm the
need of carrying out an obligatory index assessment
of bulls before their use on the farm in order to avoid receiving descendants with low dairy efficiency
In the article, long-term data (2007-2015) of biometric parameters of an elevated part of plants are provided. Assessment of prospects of five introduced botanical species of juniper is carried out and recommendations about their use in landscaping are made. From 25 studied grades of junipers of types: Cossack, Sredniy, Virginia, Horizontal and Scaly we have established very perspective, perspective and a little perspective for gardening in the conditions of a foothill zone of the Krasnodar region
