The dynamics of α-, β-amylase and summering amylase activity of single germinating spring barley seed is presented for the first time. It has been shown,
that the environment of seed growth period influences the development of ferments’ activity
The article discusses the organizational scheme of sugar beet seed production, as well as technological methods of seed production using the stick method and the cultivation of basic seeds in NRU. We substantiate the key elements of the cultivation of uterine sugar beet of summer sowing season
The ability of Phomopsis to transmit from affected seeds to plants has been studied in both anamorphic and teleomorphic phases of its development in the year of sowing. The sunflower lesion with Phomopsis affects not only the germination, but also causes the plant disease
The article presents the results of the genetic analysis of the trait ‘plant height’ for six crosses involving the forms related to different subspecies of rice. There have been estimated the types of inheritance and a number of genes, which assist to determine this quantitative trait. We have found out that the variance of the trait ‘plant height’ is determined by 3-5 pairs of genes having additive and dominant activities and the degree of dominance reduces in case the variance among parental forms increases. The non-allelic interaction of the genes of the initial forms produces transgressive dwarf and tall forms. The cross ‘Lampo’x’Virazh’ showed the highest degree of transgression in ‘plant height’ due to short height of both parental forms (61.7%), but the frequency of transgression was larger than that of the cross ‘Lampo’x’Komandor’(17.6%). This combination (‘Lampo’x’Komandor’) produced more tall forms (up to 135 cm). The segregation of a great number of tall forms into F2 testifies that the parental forms of these hybrids vary in the allelic state of several pairs of genes, whose various combinations form phenotypes with a longer stem. Thus, the semi-dwarf feature of the varieties ‘Lampo’, ‘Komandor’ and ‘Virazh’ is determined by various non-allelic genes
Experience of supervision of safety of the hydraulic engineering constructions, operating in our country since 1971, and the first 15 years of the Federal law of the Russian Federation No. 117-FZ from 21.07.1997 “About safety of hydraulic engineering constructions”, when persons under surveillance of GTS steel of power, the industry and a water economic complex is given. The majority (97 %) potentially dangerous GTS of the Russian Federation treat the IV class of solidity with service life from 40 to 50 and more years where, as a rule, is absent or the operation service, insufficient quantity of instrumentation is small. Monitoring of a technical condition of similar GTS is possible with use of the mobile, mobile complexes equipped with the modern equipment (hydrological, geophysical, geodetic, mechanical, etc.). Safety of GTS is in many respects caused by a skill level of the operational personnel. For the solution of questions of increase of their safety amending the current legislation is necessary
To control irrigation erosion, the artificial aggregation of soil by structure-forming materials was proposed in the article. The research was conducted for establishing the impact of the percent content of each fraction on soil cation exchange capacity
As a result of the research conducted there have been distinguished the sources and the donors for the subsequent usage in the selection programmers of stone-fruits assortment improvement
Trophoblast cells circulating in maternal blood may
serve as potential sources of genetic information for
screening in obstetric practice approaches to
noninvasive prenatal diagnosis. The material for the
study was whole blood of pregnant women of
gestational ages of 8-12 weeks in a volume of 10 ml.
stabilized with heparin. Enrichment was performed by
the method of gradient centrifugation and magnetic
separation (CD45–) with fluorescent staining negative
fractions labeled with antibodies to antigens of
trophoblasts (HLA-G, and Trop-2) to conduct flow
cytometry and sorting of cells on glass slides. Single
cell candidates using laser micro dissection were
transferred into a vial for subsequent whole-genome
amplification, providing sufficient representativeness
of their genome. Fetal origin of the genetic material
was confirmed by comparison of alleles of the HLA
genes of the parents and cells candidates. It is possible
to improve significantly the accuracy and versatility of
non-invasive prenatal diagnosis using comparative
genomic hybridization using chips (аCGH)
In the article, we show the results of researches on creation of a material with a fast return of moisture at ripening of a grain are resulted. The general (ACS) and specific (SCS) combinational ability of new corn lines was determined. A promising material has been identified for further work in the field of rapid release of moisture to grain during maturation
This article offers a choice of quality indicators for automating the production of soft drinks
