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 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 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
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
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
According to the results of long-term evaluation of promising hybrids of lavender angustifolia the ability to predict the influence of abiotic factors on the yield and gathering of essential oil of inflorescences is shown. Correlations, agronomic stability and variability of the yield of hybrids are defined
The process of the presowing seed treatment with
alternating electromagnet field of the commercial
frequency (EMF CF) 50 Hz is economically
efficient. The use of the EMF CF 50 Hz in the unit
with ring pole pieces allows increasing the
germinating energy and power. The electromagnet
seed treatment in the units with ring pole pieces is
the perspective process of the presowing treatment
which does not make unhealthy influence on the
operating personnel. At the presowing treatment one
has to take into account three factors; they are the
arrangement of seeds in the working chamber, the
time of treatment and the seed humidity. In this
article the authors recommend to promote the unit
consisting of a magnetic circuit with ring pole
pieces of the rectangular cross-section, a
magnetizing coil and an embedding of the nonmagnetic
material in the working chamber which
allows to increase the germinating energy of spring
barley by 10% and the germination by 6,5%. The
addition to crop capacity has run to 7% as a result of
the spring barley treatment. We analyzed the
parameters of the working chamber of the
alternating electromagnetic field source of industrial
frequency of 50 Hz, we established the dependence
of the rate of treatment on the parameters and
modes of installation, which are confirmed by
laboratory tests. Long-term field studies revealed
that the field germination rate of the seeds of spring
barley treated with EMF IF, even under adverse
weather conditions, exceeds by more than 8% of the field germination rate of control samples
In this article, the orderliness of the wheat plants phytomass increase has shown, observed until plants growth stopping time, which concurs with flowering ending. The discovered orderliness determinates the nitrogen, phosphorus and potassium (N, P, K) transfer dynamics. The mathematical model of N,P,K elements carrying out from roots - inhabited soil layer has been proposed
Kormilitsa Lisa grape was created in Greece by P. Zamanidi and L.Troshin in 2003 with crossing the varieties of the Pervenets Maharach with varieties of Muscat white. The duration of the production period is 146-155 days. The yield is high. The average mass of clusters of 250 g. It has winter hardiness, drought-resistance and high resistance to fungal diseases in comparison with varieties of Vitis vinifera; it is also tolerant to phylloxeras. The flower is ambisexual. The bunch is average, cylinder-conic, medium density. The berry is average, oval, green-yellow colour, with a thick wax coating. The skin is thin, thick, and strong. The pulp and juice with a strong Muscat flavor. Sugar content is high with acidity constant. When overripen, it dries long and is stored on the bushes. The variety is meant for manufacture of dry white wine of superior class and high-quality dessert and sweet wines; It is also suitable for the development of high-quality juices and compotes
The article deals with the problem of overgrowing of ponds and reservoirs. One way to reduce the intensity of development of plants is covering the territory with geosynthetic materials. Laboratory researches of geosynthetic materials are carried out. The optimum size of the layer of soil, which is loading geotextiles, was determined
