The article presents the results of study of the reproductive capacity of landrace varieties of winter wheat on the example of the chief of the ear. Analysis of sales productivity was conducted by the method of F. M. Kuperman. We have also considered the relation of actual productivity number formed flowers on the 6th stage of ontogenesis
The article presents the data of the yield of winter barley varieties various breeding institutions in conditions of the South zone of the Krasnodar region, as well as the analysis of selected indicators of yield structure elements
The problem of identifying of the most promising polymer materials for sledge sliding application. The comparison of materials is given: the bench tests of polyethylene, fluoroplast, steel and ultra high molecular weight polyethylene (UHMWPE) with different molecular weight and their composites are carried out. On the basis of research of polymeric samples on ice and snow friction in exploiting condition with the use of specially designed sledges was shown that GUR 4150 UHMWPE has the lowest mass volume and linear wear. Also in article the results of research of ice adhesion to different materials are presented. Adhesion research was carried out in low temperature conditions of air from -21oC up to -46oC and in cryocamera according method which was patented by Institute of oil and gas problems of SB RAS. The research showed that GUR 4150 UHMWPE has the lowest adhesion to ice. On the basis of obtained data the authors assumed that GUR 4150 is the most perspective materials for development of sledge sliding exploiting in Arctic conditions.
The article gives the overview of the non-invasive method of NMR relaxation and assess the efficiency of using this method in the study of cultured under in vitro plant objects on the example of Rosa hybrida plants
As the result of 4-year researches there were studied the main economic characteristics of the apple-tree varieties Retina, Renora, Revena Reanda, Remo and Piccolo. The varieties that were positive selected in fruit crop productivity, quality and keeping capacity were recommended for wide productive experiments. There was shown the possibility of use of studied alien varieties as pollinators
In the present work description of the structure of atomic and nanocomposite (NC) levels of crystalline materials which differs from the previously accepted is done
There were presented the results of researches of pectin influence as a cryoprotector on rheological properties of dough and physical-chemical indexes of bread quality in the article. We have also obtained the results which allow recommending pectin in the technology of bread producing from frozen semi-finished foods
Brake-off of a corn-cob from a stem occurs in expense of a corn-cob blow and pedicle distention in modern husker-shredder corn-harvesters. Any mechanical impact is connected with deformation of a corn-cob. Forces destroying connection between grains with rod appear under its deformation. Condition under which mechanical damage of a corn-cob occurs is considered in the article.
The analysis of genetic polymorphisms of 12 autochthonous grape varieties grown in the National ampelographic collection of Russia (Anapa district of the Krasnodar region) through the study of allelic diversity at six microsatellite loci: VRZAG79, VVMD5, VVMD7, VVMD27, VRZAG62, VVS2 has been done. We have found that all native varieties have a unique set of allele. The assessment of genetic relationships varieties has been performed using cluster analysis. Data for DNA certification of the investigated genotypes of the grapes has also been obtained in the article
The results of investigation of melanoidin’s formation
early stages in acidic ethanolic D-glucose – p-toluidine
model system are presented. Based on the elemental
analysis, IR- and UV-spectroscopy data obtained we
have shown, that in system studied Amadori
rearrangement product undergo the aryl amine
elimination during browning to form a nonnitrogenous
reductons with antioxidative activity in
processes of linoleic acid oxidation. It is also noted,
that in system studied inhibition of carbohydrate’s
destruction occurs because of non-reactive O-ethylglycosides
formation. The data obtained may be useful
for technology of carbohydrate-containing raw
material
