2017
E. G. Kozar | S. A. Vetrova | M. I. Fedorova | N. E. Mashenko
The protected cultivation technology, through which the various inbred generations with the combination of economic valuable traits and different level of sterility can be produced, is used in order to accelerate the breeding program. However, there is a negative effect of inbreeding depression and self-incompatibility can often occur and cause the loss of valuable breeding forms. The aim of the work was to study the influence of steroidal glycosides capsicoside (SGC) on exhibition of CMS, and morphobiological parameters of 13 inbred generations that were produced from fertile plant and partly sterile plants with level of sterility 10% and 50%. The seeds were soaked for 24 hours in water solution of SGC with concentration 10-3%, and in water control. Then the seeds were dried up and sown in the greenhouse. The stecklings and roots obtained were vernalized at 3-5Co. Mother plants were grown under 18 hour photoperiod in greenhouse with supplementary lighting. Inbreeding seeds were obtained in individual cloth isolators. It was shown that for all generations the treatment with SGC improved the seed germination (4-8% more), increased the root index and its length (12-24% more), decreased betanin content (22-48% less) in comparison with control. The action of SGC on the other morphological and biochemical traits such as height of leaf rosette, leaf number, plant and root weight, head size, number of generative buds, and nitrate content was defined by the level of sterility of mother plant. The most expressed effect for all traits mentioned was seen in inbreeding generations of sterile plants with high level of sterility. After action effect of seed treatment with SGC on development of seed plants from inbreeding generations, not depending on sterility level of mother plants, showed the positive influence on plant habitus of seed mother plants, decreasing the plant height, but increasing stem number and functional parameters of microgametophyte in fertile plants. This caused the improved seed formation 1.6-2.2 times higher during inbreeding process and increased the portion of plants with high productivity. The SGC had no effect on exhibition of CMS trait. Thus, the SGC is worth using in valuable highly inbreeding forms inclined to self-sterility, in order to enlarge the genetic variation and output of divers generations. However, it should be taken into consideration that the complicated effect on the plant traits can be noticed in inbreeding generation of red beet and may have an effect on the result of selection process at the root stage.

E. G. Gadzhimustapaeva
The plant growth stimulating preparations such as Agrostimul, Lignogumat, Ecosil and Organobor (Br) were tested in broccoli. It was shown that variety reaction in dynamic of growth of assimilation apparatus was different when treating with the preparations. The different plant responses were noticed among broccoli cultivars. The data analysis was carried out, where treated with stimulators cultivars were estimated for productivity, early-maturation, output quality, simultaneously-matured heads, duration of vegetation period, and rates of growing in comparison with control variant. As a result of the study, it was shown that economic suitability of broccoli cultivars varied depending on year temperature, and particularly the optimal time when broccoli formed heads. The application of growth stimulating preparations in open field of southern regions is very promising, in order to enhance the adaptability and yield capacity during yearround cultivation and multiple utilization of a soil unit. The treatment of seedlings and vegetative plants after having been planted and at the beginning of head formation with growth stimulating preparation was very effective way to stimulate the growth and development and to hasten broccoli head formation. In our study, the preparation Agrostimul was the most effective in increasing the yield of central heads by 181% in cultivar Burpess, Green Bud and hybrid, Cape Queen by 134%, while the yield of extra heads from the first to the third was increased by 445% and 131%, respectively.

N. N. Potrakhov | S. L. Beletskiy | F. B. Musaev
Presently the X-ray separation is used not only for research program, but it is also elaborated and applied for different sectors of economy. The seeds as biological objects that possess the complicated microstructure are very difficult to be exanimated by x-ray technology. The application of x-rays and further elaboration of optical separators, principle of action, basic specifications, way of their use and their efficiency was shown in the article. The x-ray separator may distinguish all hidden seed defects as it was described by a programmer, where owing to the use of the optical separating block in visual range it is possible to add some more details as a shape, brightness and a color of object surface being exanimated. The elaboration of such separation equipment is scientifically hard work requiring time and expenses. Last year researchers of ‘LETI’ developed the working model of industrial x-ray separator for examination of grains and nuts in different crops. This model was made on the basis of photoseparator F-5 manufactured at OAO ‘Voronezhselmash’. The instrument state and its mechanism operation are highlighted on monitor. In the regime of processing (separation and examination) of each controlled batch, the passport is produced with following information on identification code, time of material receiving, time of test passed, number of grains or seeds tested. The code of receiver of material is given to each of established characteristics when working the regime of separation, determination of number of objects with characteristics tested and number of unidentified objects. The application of x-ray separators constructed on the basis of photoseparator F-5 enables to carry out the complex estimation on seed quality and separation in only instrument with the development of electronic protocol with many characteristics.

N. А. Golubkina | A. J. Sokolova | A. V. Sindireva
Selenium deficiency is widespread among the human populations of different countries of the world and associating with cardiovascular diseases and cancer that determines the necessity to develop new technology needs to increase selenium accumulation levels by agricultural crops. Besides that, the utilization of selenium containing food supplements, soil and foliar application of selenium salts are the most popular approach to resolve the selenium deficiency problem. At the same time there is a certain drawback of selenium plant biofortification, which is a low accumulation of the element, and as a result, the possibility of environmental pollution caused the element. The review is devoted to a new direction in improving plant selenium accumulation via utilization of rhizobacteria; their participation in selenium cycle; mechanism of bacteria-selenium-plant interaction; the role of volatile compounds, released by rhizobacteria, on selenium accumulation. The questions that were separately considered were regarding rhizobacteria Microbacterium oxydans extracted from Cardamine hupingshanesis that had an exceptionally high resistance to selenium impact and ability to synthesize selenocystin.

M. I. Mamedov | O. N. Pishnaya | Y. A. Dzhos | A. A. Baykov | A. A. Matyukina
Capsicum chinense Jacq. is the rich source of phytochemical substances, such as vitamin C, phenolic compounds, carotenoids, and occupies a significant place in the cooking of many peoples. The pigment composition, the amount of carotenoids, ascorbic acid and their contribution to the formation of antioxidant properties were studied. The total content of carotenoids and red/yellow pigments varied greatly among the accessions of C. chinense. The highest content of carotenoids 0.581 mg/g was observed in the varieties ‘Ognennaya Deva’ with the red fruit color in the phase of biological ripeness, where red pigments accumulated 56% more than in yellow ones. Fruits of accessions ‘Kolokolchik’ only accumulated yellow pigments, 0.318 mg/g. Presence of significant amount, 2.03 times as much red pigments as yellow ones in the variety ‘Trinidad Scorpion Chocolate’, with protein complex could cause the formation of a brown fruit color. Another tendency was observed in ‘Trinidad Dglahou’. The yellow pigment is 1.5 times as much amount as red, as estimated 0.119 mg/g of yellow and 0.077 mg/g of red pigment. The ascorbic acid content did not depend on the fruit color. Fruits of the ‘Ognennaya Deva’ accumulated the highest amount of ascorbic acid, 301 mg%. The maximum total antioxidant content, was detected in the variety ‘Ognennaya Deva’ 2.65 (TAC, mg.eq. GA/g). Analysis of the dependence of the content of thermo stable antioxidants to the total ones showed the contribution of the unstable antioxidants to thermal effects (particularly ascorbic acid) on the level of 16%, on average. A comparative assessment of the pungency level and quantitative capsaicin content in the fruit was carried out by organoleptic, spectrophotometric and HPLC methods. The intervals of observed concentrations of capsaicin were 1.0-7.5 mg/g of dry weight (HPLC), the level of pungency on the Scoville scale was 17440-153120 SHU. There was a direct correlation between the organoleptic assessment of the pepper fruit pungency and capsaicin content studied by spectrophotometry and HPLC methods.
