Authors: Aksenov I. A.
Published: October 2020

Relevance and methods. The structure of the food market is represented by various types of products, of which the largest share is in the fruit and vegetable sector. Given the tense political situation in the world and the establishment of barriers in foreign trade, agriculture is a strategically important sector of the Russian economy. Today, the fruit and vegetable branch of the Russian economy does not fully satisfy the population’s needs for fruits and vegetables. This is evidenced by the fact that the domestic market does not provide the population with high-quality vegetables and fruits, creates favorable conditions for filling it with foreign goods, which make up about 35% of the consumer basket of Russians. All this leads to the need for additional analysis to identify trends in the Russian market of fruits and vegetables and identify priority areas for its development. The purpose of the article is to identify the features of the functioning of the fruit and vegetable market in Russia. The study was based on statistics from the customs authorities of the Russian Federation on the import and export of fruits and vegetables, as well as the Federal State Statistics Service on production, consumption of fruits and vegetables in Russia. The article discusses the features of the functioning of the fruit and vegetable market in Russia. The key factors that influence the development of the market of fruits and vegetables at the present stage are determined.

Results. As a result of analysis of the state of the market of fruits and vegetables in Russia in 2011-2020. it can be stated that the fruit and vegetable market is experiencing difficult times due to the sanctions policy of the EU and the USA and the low level of material, technical and logistics base in Russia. The advantages of the market of fruits and vegetables during the period of antiRussian sanctions are reflected. Groups of problems of functioning of the market of fruits and vegetables are revealed. Based on the identified problems of the fruit and vegetable market, methods for solving them are proposed based on the best practices of the European Union. The article focuses on the development of the market for fruits and vegetables in Russia. The proposed solutions and development directions are substantiated by specific figures of economic efficiency.

Authors: Ignatova S. I. , Babak O. G. , Bagirova S. F.
Published: October 2020

Relevance. High lycopene fruit content has been regarded as a very important genetic trait in tomato breeding. Use lycopene molecular markers in combination with conventional breeding techniques allowed us to create hybrids with high lycopene accumulation, excellent organoleptic qualities, high yield production and resistance to pathogens, and to effectively optimize our breeding programmes for commercial greehouses production.

Material and Methods. In this study tomato samples including selected lines and hybrids with various allelic combinations of genes determining carotene accumulation, and other genetic traits, such as disease resistance and yield production were tested. Introgression of spontaneous and induced mutations was used to increase carotenoid levels (og and hp) and improve fruit technological qualities (nor, alc, rin). The research material was tomato collection, mutants, breeding lines and hybrids listed in the State Register Russian Federation tomato hybrids of breeding SS Agrofirm "Ilyinichna" VNIIO branch of the All-Russian Scientific Research Institute of Vegetable Growing – Branch of the FSBSI Federal Scientific Vegetable Center. DNA typing of fruit quality genes was performed at the Institute of Genetics and Cytology of the National Academy of Sciences of Belarus.

Results. New domestic hybrids for industrial greenhouses, which characterised by improved organoleptic qualities and technological traits were developed with the help of phasedcross-breeding that allowed to combine the genes nor, rin, alc, leading to an extension of the shelf life with the genes B, og, hp1, etc., contributing to an increase in carotenoid content in fruits. It was established that for targeted selection and hybridization, despite the negative influence of the nor, rin, alc genes it is possible to raise the level of carotenoids to average values. Correlation between lycopene concentration in fruits and high temperature and level of insolation was confirmed. It was shown that pink-fruited forms contain significantly more lycopenethanred-fruitedones. Different all eliccombinations of structural genes involved in carotenoids biosynthesis and regulatory genes that provided maximal accumulation of lycopene in hybrid swithred and pink fruits were revealed. Hybrids with the combination of high concentrations of sugar (° Brix), dry matter and maximal lycopene values, combined defining excellent taste were selected: Prekrasnaiya lady, Olya, Quadrille, Victoria. New F1 hybrids one for industrial greenhouses: G950, G956, G960, Magistral and pink fruited G12897, surpassed the Dutch standard in productivity up to 21%, and in tastes/organoleptic qualities for 1-1.8 points.

Published: October 2020

Relevance. The creation of heterotic hybrids of watermelon is one of the modern breeding trends for solving the problem of providing the population of the Russian Federation with melon production. The process of creating heterosis hybrids can be accelerated by the assessment of the total combination ability (ОCS) of parental lines.

Materials and methods. The studies were carried out in the zone of the Volgograd Trans-Volga region at the Bykovskaya melon selection experimental station, in dry conditions in 2018 and 2019. The object of research was 9 paternal lines and 3 maternal lines of watermelon. The assessment of the general combining ability was carried out according to two indicators: yield and dry matter content.

Results. In the course of the research, the obtained F1 watermelon hybrids were assessed for a set of economic characteristics in comparison with the standards: Zenit, Sinchevsky and Barkhan. Based on the results of the work, F1 hybrids were identified according to the length of the growing season, yield, and dry matter content. By selecting valuable genetic sources with a high GCS, it is possible to successfully conduct breeding to improve the economically valuable indicators of F1 watermelon hybrids. According to the results of studies on yield, both in 2018 and in 2019, heterotic hybrids were distinguished, obtained from crossing with the paternal lines Favorit, Stimul, Ikar, the average effect over two years ranged from 3.5-10.6 t/ha. Among the studied maternal lines, the line Chms-4 has a positive effect, the average effect was 1.2 t/ha. In terms of dry matter content, a positive effect was found in the paternal lines Stimul – 1.8%, Medunok – 1.6%, Favorit – 0.8%, and in the maternal line Chms – 41.8%

Conclusions. Based on the results of the analysis of the combining ability in terms of yield and dry matter content, we identified two promising paternal lines for creating heterotic watermelon hybrids: Favorite, Stimul. Also, one maternal line Chms-4 was distinguished. When using these lines in heterotic breeding of watermelon, in most crossing combinations, heterosis will be manifested in one or two characters.

Authors: Kozar E. V. , Kozar E. G. , Soldatenko A. V. , Domblides E. A.
Published: October 2020

Relevance. Doubled haploids (DH-plants) are excellent material for genetic research and breeding due to their complete homozygosity. The genus Raphanus from the Brassicaceae family is the toughest to produce doubled haploid plants through isolated microspore culture in vitro (IMC). The study of the causes of disturbed root formation and the development of elements of this stage of technology will significantly increase the effectiveness of the IMC technology for European radish.

Methods. The study included three varieties from the collection of the Federal State Budgetary Scientific Institution Federal Scientific Vegetable Center (FSBSI FSVC): Teplichny Gribovsky, Rozovo-krasniy s belim konchikom and Rhodes. The experiments used a standard protocol for obtaining DH plants using IMC technology in a standard form and with a modification of the rooting stage. The solid MS medium (with agar 7g/L): MS without hormones, MS medium supplemented with IAA at concentrations of 0.5; 1 and 2 mg / L and liquid MSm medium supplemented with 0.1 mg / L kinetin were used for rooting of regenerated plants. All media were supplemented with 20 g/L sucrose. We used three types of techniques for transplanting plant explants onto a solid hormonefree MS medium: planting micro-shoots with their basal part immersed by 2-3 mm into the medium; planting in a well made in a nutrient medium using tweezers under sterile conditions; and landing on the surface of the medium without embedment.

Results. In this work, we studied the features of the stage of rooting of regenerated European radish plants in vitro conditions. The transplant technique has been proven to be important for the successful establishment of radish micro-shoots. Plant explants must be planted strictly on the surface of a solid hormone-free nutrient medium MS, without embedment. The use of tubes with bridges made of filter paper and MSm liquid medium with the addition of 0.1 mg/L kinetin for the induction of root formation also showed high efficiency. For plants prone to the formation of root-like structures (RLS) with secondary tumors (ST), multiple dissection of abnormal formations with successive transplants is necessary. Modification at the rooting stage of micro-shoots growing has increased the percentage of successfully adapted DH plants in vivo conditions from 0-14% to 95-98%.

Authors: Borovskaya A. D. , Mashchenko N. E. , Ivanova R. A. , Gumanyuk A. V.
Published: October 2020

Relevance. Increasing the resistance of vegetable plants to unfavorable growing conditions with the use of growth regulators that actively affect the seed quality, increase the survival rate of seedlings, stimulate the setting, formation and maturation of the crop is a significant reserve for increasing productivity with the already achieved level of intensification of their production.

Material and methods. The effect of verbascosides obtained by exhaustive extraction with 60% aqueous ethyl alcohol from the aboveground part of Verbascum densiflorum Bertol. (Scrophulariaceae) was studied on the germination, growth, development and yield of tomatoes, cucumbers, onions and white cabbage. Before sowing, the seeds were soaked in an aqueous solution of verbascosides for 15-20 minutes, followed by drying to flowability at the rate of 0.5-0.8 liters of solution per 1 kg of seeds.

Results. It is shown, that possessing phytoregulatory activity and influencing the metabolic and synthetic reactions of plants, these compounds, applied exogenously, stimulate the seed germination energy and total germination of vegetable crops, provide simultaneous appearance of seedlings and optimal plant density, accelerate the growth dynamics of plants assimilation surface and fruit mass. Reducing the consequences of stresses arising in the process of plant growth and development, they thereby contribute to increasing plant resistance, productivity and improving the commercial quality of the products. The ability of these compounds to improve the production process of vegetable crops, depending on the type and variety of vegetables was established. Their highest stimulating effect was determined on cabbage variants, where the yield exceeded the control by 34.3%. The performed studies and obtained results allow to recommend the pre-sowing seed treatment with a 0.01% solution of biological active substances from Verbascum densiflorum Bertol. as an element in technology of growing vegetable.

Authors: Prudnikov P. S. , Golyayeva O. D.
Published: October 2020

Relevance. In modern climatic conditions, the suppression of production process occurs against the background of short-term or long-term exposure to unfavorable environmental factors on agricultural plants, and, therefore, yield decreases. In this regard, there is a need for the use of growth regulators with protective and stimulating effects on many physiological processes.

The aim of the work was to study the influence of the element selenium and 6-benzylaminopurine on the production process of red currant.

Methods. Foliar treatments with solutions of sodium selenite and 6-benzylaminopurine (6-BAP) were made after flowering plants of the Dana and Asya varieties of the VNIISPK. The currant leaves were taken from annual shoots for determine the content of abscisic acid (ABA), the amount of pigments, and the rate of light reactions of photosynthesis. The parameters of the fruit brush of plants were recorded.

Results. It was shown that treatments with sodium selenite and 6-benzylaminopurine contribute to a decrease of 2.1-3.5 times in the leave tissues of the endogenous ABA level, increase the chlorophyll biosynthesis by 27.5-48.0% and accelerate by 19.3-45.8% electron transfer rate on the level of light photosynthesis reactions. Treatment with selenium and 6-BAP of Dana plants increased the average mass of the fruit brush by 19.30% and 24.5%, respectively, Asya varieties by 20.7 and 35.8%. The increase in the average mass of the fruit brush occurred due to the enlargement of the average mass of one berry in it. It was shown that selenium and 6-BAP in the Dana variety increased the weight of the berry by 27.3% and 47.3%, in Asya by 33.3% and 45.8%. The treatment did not have a significant effect on the amount of sugars. Thus, for increase the production process, it is advisable to make foliar treatments with sodium selenite and 6-BAP during the growing season on red currant plants.

Published: October 2020

Relevance. A rare representative of the Apiaceae family the garden chervil is widely used abroad in nutrition and in folk and traditional medicine.

Methods. Evaluation of nutritional potential of Anthriscus cerefolium (L.) Hoffm and Anthriscus sylvestris Hoffm grown in Moscow region is achieved using the parameters of ascorbic acid, polyphenols, flavonoids, total antioxidant activity of ethanolic extracts.

Results. Garden chervil (Anthriscus cerefolium) was characterized by lower concentrations of ascorbic acid (1.6-1.8 times), phenolics (2.2-2.5 times), flavonoids (1.8-2.2 times), total antioxidant activity (1-1.54 times) and dry matter content (2.4-4.9 times) than wild chervil (Anthriscus sylvestris) but demonstrated significantly higher levels of total dissolved solids. Significantly higher content of dry matter in leaves and especially stems of wild chervil correlates with low nutritional value of stems despite large total mass of plants compared to garden chervil. Contrary to wild chervil, Anthriscus cerefolium recorded unusually high concentrations of carotene in leaves and significantly lower levels of chlorophyll b. Seeds of garden chervil were also characterized by low antioxidant status contrary to wild chervil and seeds of curly parsley. High yield and significant nutritional value of garden chervil indicate important prospects of its wide-scale cultivation in Russia while Anthriscus sylvestris plants seem to be important in breeding processes.
Comparative evaluation of several Dynamics of accumulation of lactic and acetic acids in the process of directed fermentation of white cabbage of the Parus variety
Authors: Kondratenko V. V. , Posokina N. E.
Published: October 2020

Relevance and methodology. Today, white cabbage is the most popular type of vegetable raw materials used for fermentation not only in Russia, but also in other countries. To obtain a variety of flavors and shades of flavor, various vegetables (carrots, sweet peppers), fruit (apples, cranberries) and spicy-aromatic additives (cumin, dill seed, etc.) are added to the cabbage during fermentation. During fermentation, the product contains not only the initial components of the raw material (vitamin C, macro-and micronutrients), but also significantly increases the number of lactic acid microorganisms – the main "participants" in the process.One of the main products of the metabolism of lactic acid microorganisms is lactic acid. At a concentration of 0.5%, it begins to inhibit the development of many microorganisms. When reaching a concentration of 1-2% microbiological enzymatic hydrolysis, as a rule, ceases. The accumulation of acetic acid allows us to judge the intensity of the heterofermentative stage of fermentation using strains of lactic acid microorganisms.

Results. The L. plantarum + L. casei consortium has shown a synergistic interaction in the accumulation of lactic acid, since the amount of acid produced by the consortium significantly exceeds the amount of acid produced by each strain separately. This point is also noted for the accumulation of acetic acid. In the L. brevis + L. casei consortium, the opposite situation is observed: when using cultures separately, the accumulation of lactic acid occurs to a greater extent than when using two cultures simultaneously. There are no obvious differences between monocultures and the consortium in terms of acetic acid accumulation. In the case of the L. plantarum + L. brevis consortium, we observe a synergistic interaction, with the dominant role in this consortium played by L. plantarum, and the contribution of L. brevis to the accumulation of lactic acid is insignificant. At the same time, the total resulting accumulation of acetic acid is significantly less than the result of each strain separately, which may indicate a negative mutual effect of the participants in the process. Acid degradation of the polysaccharide matrix of cell walls does not occur during the entire fermentation process.

Authors: Patsyuk L. K. , Fedosenko T. V. , Kondratenko V. V.
Published: October 2020

Relevance. The article presents the results of a study of the increase in the amount of reducing sugars in the inversion of sucrose due only to thermal effects during ultrasonic processing of vegetable and fruit monocomponent purees (with or without added sucrose). The relevance of the study is to identify the quantitative thermal component of a separate process in the total inversion of sucrose at the specified parameters of ultrasonic action on the product.

Material and methods. to perform this task, experimental samples of carrot, pumpkin and Apple puree with the addition of sucrose in an amount of 5% (by weight) and without it were previously made, which were then subjected to heat treatment at the same temperature and time exposure (at a temperature of 50 °C for 30 minutes). To study the dependence of the degree of sucrose inversion on the component composition of the processed product, the mass fraction of reducing sugars – fructose and glucosewas determined in the manufactured experimental samples of natural fruit and vegetable purees (without added sucrose) and in mixtures of purees with sucrose (according to a given recipe) before and after heat treatment at the specified parameters, depending on the recipe composition and pH of the medium.

Results. The obtained results of the study of the carbohydrate composition before and after thermal exposure show that the amount of reducing sugars in products subjected to heat treatment has significantly increased, compared to the initial content. Thus, in Apple puree with added sucrose, the mass fraction of fructose after heat treatment of the mixture increased by 197 mg per 100 g, i.e. by 3.8%, and glucose – by 192 mg per 100 g, i.e. by 6.7%. The total invert sugar content of the Apple mixture increased by 4.8 %. In the carrot mixture of puree with sugar, the content of total reducing sugars after thermal exposure increased by 5.4%. At the same time, in carrot natural puree, the increase in reducing sugars was only 3.6%, which is 1.5 times lower. In the pumpkin puree mixture with sugar, the total content of reducing sugars increased by 3.9%, and in the natural puree, the amount of invert sugars increased by only 2.7%, which is 1.4 times lower than puree with added sugar.

Livestock systems are based on the monoculture of grasses, grazing does not usually take into account the physiology of the species, this affects the persistence and quality of the forage. Silvopastoral systems favor forage production and quality, it is important to know the growth dynamics of the pasture to determine the optimal grazing moment. The objective of this work was to evaluate the effect of Acacia melanoxilum on the production and nutritional quality of a mixed meadow in the high tropics. The research was carried out at the “Santa María del Puyón” Research and Training Center, located in Sopo, Colombia. A meadow of Cenchrus clandestinum and Lolium perenne was evaluated, in alley pastures, plots were established under and outside the trees, the growth was evaluated (15, 30, 45 and 60 days) for nine months. The physicochemical properties of the soil, undisturbed height, number of leaves, leaf area index, production and quality of forage were determined. A random design was used, descriptive statistics and analysis of variance were performed. The Infostat® program was used for data analysis. Under the trees there is a higher ph, organic matter, minerals and cation exchange capacity, higher undisturbed height (p = 0.0001), differences in green forage production (p = 0.0128), botanical composition, and higher protein crude (p = 0.0061). A. Melanoxilum trees favor the growth and nutritional quality of mixed grasslands in the high tropics

Published: October 2020

Чешката народна самостоятелност беше много важен предмет на социанo и културно обсъждане в 20-то десетилетие на 20-ти век в Чехия. Тази дискусия беше заглушена във следваща декада по причина на икономоческата криза в началото на 30-те години. Периодът, кога тема на чешката народна идентита беше важно отново, стана в моментта на нарастваща опасност от национализъм в Германия. Това се открива в чешката литература. В литературната историа има течение, който тематизира селския живот. Авторите използват почвата като симбол — тя представлява семейство и народна памет. Връзката между почвата и хората (които живеят и работат на тази пръстта) повлияе характеристика и поведение на ги, и то е приемано като дял от народната самостоятелност. Тази студия се занимава с избрани новели, именно Puszta (Josef Knap, 1937) и Ztracená země (Václav Prokůpek, 1938), и открие, как е изобразена чешката народна самостоятелност и как този произведения изобразяват развитието на съвременната дискусия.

Published: October 2020

Amorphous silicon (α-Si) film present an inexpensive and promising material for optoelectronic and nanophotonic applications. Its basic optical and optoelectronic properties are known to be improved via phase transition from amorphous to polycrystalline phase. Infrared femtosecond laser radiation can be considered as a promising nondestructive and facile way to drive uniform in-depth and lateral crystallization of α-Si films that are typically opaque in UV-visible spectral range. However, so far only a few studies reported on utilization of near-IR radiation for laser-induced crystallization of α-Si providing no information regarding optical properties of the resultant polycrystalline Si films. The present work demonstrates efficient and gentle single-pass crystallization of α-Si films induced by their direct irradiation with near-IR femtosecond laser pulses coming at sub-MHz repetition rate. Comprehensive analysis of morphology and composition of laser-annealed films by atomic-force microscopy, optical, micro-Raman and energy-dispersive X-ray spectroscopy, as well as numerical modeling of optical spectra, confirmed efficient crystallization of α-Si and high-quality of the obtained films. Moreover, we highlight localized laser-driven crystallization of α-Si as a promising way for optical information encryption, anti-counterfeiting and fabrication of micro-optical elements.

Respiratory syncytial virus (RSV) is associated with adverse outcomes among immunocompromised patients. Inhaled ribavirin has been shown to improve mortality rates. The Small-Particle Aerosol Generator delivery system (SPAG-2) is the only FDA-cleared device to deliver inhaled ribavirin. However, it is difficult to set up and maintain. We developed a method for delivery of this medication using the vibrating mesh nebulizer (Aerogen®). We did not observe any adverse events with this method.
New Bioadsorbent Derived from Winemaking Waste Cluster Stalks: Application to the Removal of Toxic Cr(VI) from Liquid Effluents
Authors: Alcaraz Lorena , Alguacil Francisco J. , López Félix Antonio
Published: October 2020

A winemaking waste was used as a precursor of activated carbon used in hazardous Cr(VI) removal from solutions. The preparation process consisted of a hydrothermal process, and a chemical activation, of the resulting product, with KOH. The adsorption results showed that the adsorption of Cr(VI) on the obtained activated carbon is strongly dependent on the stirring speed applied to the carbon/solution mixture, pH of the solution, and temperature. The equilibrium isotherm was well fitted to the Langmuir type-II equation, whereas the kinetic can be described by the pseudo-second-order kinetic model. Thermodynamic studies revealed that Cr(VI) adsorption was an exothermic and spontaneous process. Finally, desorption experiments showed that Cr(VI) was effectively desorbed using hydrazine sulfate solutions, and at the same time, the element was reduced to the less hazardous Cr(III) oxidation state.

Variable voltage DC power supply that has wide range of power, lightweight and inexpensive is quite difficult to obtain. This research designs and tests a DC power supply without a transformer using switching technology that utilizes TRIAC. The 220 Volt AC power source is converted to DC electricity by the method of cutting off some AC waves signal, using TRIAC, and then rectifying it with diodes and filters. DIAC functions as a trigger TRIAC at the specified time, by turning the variable resistor. The test results show that the output DC power voltage can be adjusted from 5 Volts to 75 Volts by adjusting the DIAC resistance and the load resistance. The results of the series image characteristics are given 2-dimensional and 3-dimensional graphics.

To prevent the outbreak of the Coronavirus disease (COVID-19), numerous countries around the world went into lockdown and imposed unprecedented containment measures. These restrictions progressively produced changes to social behavior and global mobility patterns, evidently disrupting social and economic activities. Here, using maritime traffic data, collected via a global network of Automatic Identification System (AIS) receivers, we analyze the effects that the COVID-19 pandemic and the containment measures had on the shipping industry, which accounts alone for more than 80% of the world trade. We introduce the notion of a “maritime mobility index”, a synthetic composite index, to quantitatively assess ship mobility in a given unit of time. The mobility index calculation used in this study, has a worldwide extent and is based on the computation of Cumulative Navigated Miles (CNM) of all ships reporting their position and navigational status via AIS. We compare 2020 mobility levels to those of previous years assuming that an unchanged growth rate would have been achieved, if not for COVID-19. Following the outbreak, we find an unprecedented drop in maritime mobility, across all categories of commercial shipping. The reduced activity is observable from March to June, when the most severe restrictions were in force, producing a variation of mobility quantified between -5.62% and -13.77% for container ships, between 2.28% and -3.32% for dry bulk, between -0:22% and -9.27% for wet bulk, and between -19.57% and -42.77% for passenger shipping. The presented study is unprecedented for the uniqueness and completeness of the employed AIS dataset, which comprises a trillion AIS messages broadcast worldwide by 50,000 ships, a figure that closely parallels the documented size of the world merchant fleet.
