Relevance. The non-chernozem zone of Russia and the more northern regions of the country are far from the most favorable zones for the cultivation of tomatoes in open ground. The most promising for the northern zones of Russia are earlyripening, cold-resistant varieties and hybrids of tomato. The most promising in terms of productivity, resistance to short-term frosts and late blight damage are standard and semi-standard forms of tomato. Stamp forms (var. validum Brezh.) are of significant interest, both for breeding, genetic studies of tomato culture, and for production.Results. In the laboratory of selection and seed production of solanaceous crops of the FSBSI FSVC (VNIISSOK) in recent years, a whole series of standard early ripe tomato varieties for open ground has been created (Chelnok, Revansh, Pervotsvet, Argo, Evgeniya, Malinka, Otradny). The involvement of the selected standard forms in the crosses made it possible to create a number of promising lines and varieties of the semi-standard form (Perst, Pervotsvet, Blagodatny, Dolgonosik, Voskhod VNIISSOK), which significantly increases the genetic diversity of the standard forms. These varieties with a solids content of up to 7.5%, with a long shelf life. In the non-chernozem zone and the more northern regions of the country, the VNIISSOK selection varieties easily tolerate a short-term decrease in day and night temperatures to 0…-1°C, and in the southern regions drought.

Relevance. Vegetable seed production is a key step in using of new varieties/hybrids in agriculture. The main problem of vegetable seed production is the negative effect of environment to the seed productivity of plants and seeds quality. Usually, vegetable seeds produce in greenhouses in Russia, but special greenhouses are necessary for the obtaining of qualitative seeds. Possibilities different types of greenhouses for seed production of new special tomato varieties for multi circle hydroponics have been studied at this paper.Materials and methods. Materials of study: plants, fruits and seeds of two new tomato varieties Natasha and Timosha. Influence type of plants cultivation on the yield, plant productivity, the middle mass of the fruit and seeds quality have been studied at the two factorial experiment, which has been carried out with help of random repetitions method with 4 repeats. Seed quality has been evaluated by GOST 32 592-2013. Experimental data have been calculated with dispersion analysis by B.A. Dospekhov (1985).Results. It has been established, that the environment of “Rishel” greenhouse (France firm “Rishel”) with polycarbonate cover is optimal for the seed production of new tomato varieties Natasha and Timosha for multi circle hydroponics. The productivity and the yield of seed’s plants were significantly higher in “Rishel” greenhouse, than in the usual greenhouse. The middle mass of one fruit at the plant was significantly higher too. The quality of seeds was in accordance to GOST 32 592-2013 for qualitative tomato seeds (2014).

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.

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.

Relevance. Biofortification of agricultural crops with selenium is considered to be the most promising method for the human selenium status optimization.Methods. Effect of foliar biofortification of cauliflower, Polyarnaya Zvezda cv, with sodium selenate of different concentrations on yield, selenium content and biochemical characteristics of plants were investigated.Results. Enrichment of plants with selenium increased yield by 1.23-1.31 times, sugar content – 1.6 times, ascorbic acid concentration – 1.52-2 times. On the contrary, the treatment did not affect pholyphenol content and antioxidant activity of ethanolic extracts of plants. Selenium accumulation levels decreased according to inflorescences > leaves > roots. Sodium selenate solution at 75 mg/L concentration increased mass of cauliflower leaves 1.9 times and roots – 1.5 times. Consumption of 100 g of cauliflower fortified with 50 mg/L sodium selenate solution provided 100% of the daily adequate selenium consumption level. Utilization of higher sodium selenate concentrations ensured 127% and 418% of the daily adequate consumption level in case of 75 mg/L and 100 mg/L concentrations respectively. Taking into account insignificant differences between sugar content and antioxidants in cauliflower inflorescences fortified with different doses of selenium the most suitable concentration to be used was 50 mg/L.

Relevance. The Volgograd region is one of the major producing regions of table carrots with a difficult climate, therefore, regional adaptation of technology parameters and optimization of reclamation regimes under drip irrigation is necessary. According to most researchers, it is important to take into account the weak development of the root system of carrots in the initial periods of plant growth and development, so the differentiation of the moistened soil layer will allow more rational and productive use of soil moisture.Materials and methods. The working hypothesis of the studies was the assumption that it is possible to intensify the production process of carrots when managing water and mineral nutrition by drip irrigation against the background of high-quality soil preparation with the formation of ridges and the use of modern sowing units. In accordance with the hypothesis put forward, the research program is based on the assessment of threshold values of the conditions for the appointment of vegetation irrigation with drip irrigation and doses of mineral fertilizers.Results. The determination coefficient of the estimated dependences of the carrot water consumption coefficient on the duration of maintaining the starting irrigation regime and mineral nutrition conditions is 0.87-0.94, which characterizes a strong relationship between the indicators included in the equation. it was beneficial for Cordoba F1 hydride to maintain the starting regime of carrot irrigation, oriented to moisten the calculated 0.2-soil layer, to the stage of formation of the 2nd leaf, as well as to apply mineral fertilizers with a dose of N240P90K315 of the planned yield level, 120 t/ha was not received. The productivity of other hybrids studied in the experiment did not exceed 100 t/ha; therefore, it is advisable to introduce mineral fertilizers with a dose of N190P75K245, calculated specifically for this level of planned yield.

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.
