The article presents the results of studies of the chemical composition, commercial qualities and taste of berries of promising strawberry varieties breeding of the All-Russian Horticultural Institute for Breeding, Agrotechnology and Nursery (Moscow) in the conditions of the Orenburg Urals. The studies were carried out in 2016-2018 on the basis of the Orenburg Experimental Station of Horticulture and Viticulture of the All-Russian Horticultural Institute for Breeding, Agrotechnology and Nursery in specific conditions, where almost annually dry and moderately dry climatic periods were observed during the formation of the yield (May-June). A comparative evaluation of varieties on the content of sugars, acids, vitamin C in berries, taste and attractiveness of appearance is given. The dependence of the studied parameters on the genotype of the variety and vegetation conditions was established. Depending on the variety and year, the content of soluble solids varied from 7.2 to 10.2 %, with an average content of 8.9 %; total acidity varied from 0.8 to 1.2 %, with an average content of 1.0 %; the content of ascorbic acid (vitamin C) was from 45.1 to 78.5 mg/100 g, with an average content of 56.4 mg/100 g. Varieties with high parameters of tasting evaluation (Darenka, Kokinskaya Zarya, Studencheskaya), soluble solids (Rosinka, Studencheskaya) and ascorbic acid (Kokinskaya Zarya, Bereginya) were revealed. They are recommended to be grown to obtain fresh consumption products and as processing products of various directions. Bereginya, Darenka and Rosinka varieties surpass control varieties in certain biochemical parameters and can be used in breeding in the Urals region to obtain new genotypes with an increased content of a specific biologically active substance. The variety Tsaritsa is selected for high commodity qualities of berries (weight, dessert taste, attractiveness of appearance) and is recommended for commercial production of berries and involvement in breeding process. It has been established that the taste of berries is determined by a complex of acids, sugars and aromatic substances. This parameter was greatly influenced by weather conditions, from which air temperature and precipitations were determining.

The fruit physical and chemical characteristics can vary during the maturation period and this variation depends, among other factors, on the weather conditions during fruit development. This study aimed to evaluate the changes in physical and chemical characteristics of eight peach cultivars during two seasons. The cultivars Campinas 1, Coral, Maciel, Marli, Premier, Regis, Rei da Conserva and Tropic Beauty were planted on Okinawa rootstock at the experimental orchard of the Federal University of Viçosa (UFV), Viçosa-MG, Brazil, in 2008 and the following characteristics were evaluated: fruit weight, skin color, firmness, soluble solids, titratable acidity, ascorbic acid and total carotenoids. The experiment was conducted during 2011 and 2012 growing seasons in a completely randomized design with eight treatments (cultivars), three repetitions and 10 fruits per plot. There were differences between the variables for the two seasons, with the largest variations observed for firmness, ascorbic acid and total carotenoids. Cultivars Maciel and Marli produced fruit with higher mass, Tropic Beauty with greater firmness and Rei da Conserva, Coral and Marli with higher soluble solids contents. The cultivar Rei da Conserva presented higher values for most of the evaluated variables in both seasons. The yellow color, evaluated by the hue angle, is associated with total carotenoids content in peaches.

Ethephon is used to accelerate fruit ripening on plantations with well-developed plants which have formed a large quantity of fruits. The aim of the study was to determine the effect of ethephon on the chemical composition of the fruits of seven cultivars of processing tomato (‘Rumba’, ‘Hubal’, ‘Sokal’ F1, ‘Mieszko’ F1, ‘Polset’ F1, ‘Hysioux’ F1 and ‘AF1120’ F1), applied to the plants when most of the fruits had reached the mature-green stage. The study was conducted during three consecutiveyears, characterized by different weather conditions. Meteorological elements, i.e. air temperature and precipitation totals, were monitored in the experimental station in Mydlniki, near Krakow, Poland. Ethephon was found to have a beneficial effect on the content of extract and soluble sugars of the harvested tomatoes and on their acidity. Dry matter and lycopene levels were not dependent on the use of this compound, while the ascorbic acid content was reduced by the procedure. The chemicalcomposition of the tomato fruits differed significantly in consecutive years of the study, which confirmed the weather impact on fruit quality and on the varied responses of different cultivars to use of ethephon. The tested cultivars were also compared in terms of their suitability for processing. The ‘Hubal’ cultivar had the highest content of dry matter, extract, soluble sugars of all the cultivars tested. The highest level of lycopene was noted for the tomatoes of the ‘Rumba’ and ‘Sokal’ F1 cultivar, ascorbic acid of the ‘Rumba’ and the highest acidity for ‘AF 1120’ F1.

Introduction. The present research featured the antioxidant complex of Russian tea varieties. The research objective was to study the formation patterns of the components responsible for the quality characteristics of tea as a raw material and finished product. The paper describes the changes that the biochemical composition of tea undergoes during the growing season and during processing. The study focused on pigments, vitamins, caffeine, and amino acids. Study objects and methods. The research featured the following varieties of tea grown in the Krasnodar region of Russia: “Kolkhida” (control) and “Sochi”; forms – No. 582, 3823, 855, and 2264. The research was performed on the foundation plantation of collection tea in the village of Uch-Dere (Lazarevsky district of Sochi, Krasnodar region, Russia) and in the laboratory of plant physiology and biochemistry. The study involved traditional and advanced research methods. Results and discussion. The paper introduces some results of a comprehensive analysis of the biochemical composition of various tea sorts. Shoots No. 2264, 3823, and the “Sochi” variety demonstrated high values of ascorbic acid. Form No. 3823 and the “Sochi” variety proved to have a relatively stable content of ascorbic acid. All experimental plants had the highest caffeine synthesis in July (from 24.633 to 28.614 μg/100 g). Processing destroyed caffeine and reduced its amount. The experimental samples of raw materials had eleven amino acids, the largest number being synthesized in May. Processing triggered both general changes in their quantity and varietal differences in the metabolic reactions of amino acid conversion. Conclusion. The tea flushes and finished products differed in all biologically active substances, which is associated with both varietal characteristics and the effect of weather conditions during vegetation.

A comparative study has been made with a view to clarification of the quality properties of some home-grown black-currant varieties. Twelve varieties were examined; samples were obtained from 6 different localities, of which the southernmost was Piikkiö, and the northernmost Rovaniemi, over a period of three years. The analytical results were compared with the totals of heat, the totals of hours of sunshine, and the precipitaition during the years concerned. Ascorbic acid, one of the most important criteria of quality, was assayed by application of the method of Robinson & Stotz, slightly modified. On the basis of the results obtained, mutual comparison of the varieties studied is possible along with consideration of the possible effects of weather conditions and the degree of north latitude of the place of growth. It is well known that the ascorbic acid content is dependent upon the variety. Accordingly, the following diminishing sequence was found in the ascorbic acid content of the varieties studied: Boskoop, Roodknop, Westwick Choice, Wellington XXX, Gerby, Wellington X, Åström, Brödtorp, Goliath, Silvergieter, Janslunda and Black of Lepaa. In this series, the amount of ascorbic acid fell from 250 to 127 mg/100g; considerable variations occurred in each variety. As for weather conditions, the summer temperature showed the greatest effect; in general, low temperature increased the amount of ascorbic acid. However, Brödtorp and Black of Lepaa often formed an exception. The number of hours of sunshine produced a similar effect, but to a lesser degree; by contrast, precipitation evinced no clear-cut effect. The degree of north latitude of the locality also seems to exert some effect, probably mainly because a latitude further north means a lowering of the temperature, and consequent retardation of the ripening, which again causes higher ascorbic acid values. Comparison with published reports shows that in principle the present results are in line with those presented earlier. The differences might be attributable to different methods of assay, or variability in the varieties concerned. The northern latitude of the place of growth and the degree of maturity may be of importance.

The influence of weather conditions of the vegetation period on the formation of the food value of cauliflower was studied. Weather conditions of the vegetation period influenced the formation of the food value of cauliflower. More dry substances 8,4–15,5 % depending on a hybrid accumulated in a drying and hot 2017 year. The content of dry substances in heads of early ripen hybrids of cauliflower during 2015–2017 was within 6,1–10,9 % depending on a hybrid. In 2016 and 2017 there accumulated more of them. The more total content of sugars, saccharose formed in heads of cauliflower in 2015 and 2017. The content of ascorbic acid in early ripen hybrids was higher in 2015, which weather conditions in the period of ripening of heads were less drying comparing with other ones. It was established, that the main sign-indicator is the content of dry substances that directly correlated with weather conditions of the vegetation period. The content of dry substances in heads of early ripen hybrids has a strong reverse connection with an air humidity in the period of head formation: r=–0,8‑0,93, and also strong direct connections with a sum of precipitation and HTC of the vegetation period. The content of dry soluble substances has a strong reverse connection with an air humidity: r=–0,7–0,97. There was elaborated a regression equation that helps to prognosticate the total content of sugars, saccharose, reducing sugars in cauliflower heads depending on dry soluble substances. It was established, that the duration of the vegetation period in hybrids, studied in average for three years, was not equal and varied from 72 days in a hybrid of Livingston F1 (control) to 83 days in hybrid Kul F1.

Active Substances

Grapes is a highly valuable food product due to the presence in it of a number of biologically active substances, among which vitamins occupy a special place. One of the most important and studied in grapes is vitamin C (ascorbic acid). The ascorbic acid contained in plant tissue participates in redox metabolism, thereby increasing the resistance of plant organisms to infections and low negative temperatures. Studies aimed at determining the concentration of vitamin C in plant material are important both for breeding and for identifying the most sustainable competitive varieties. The purpose of these studies is to study the content of vitamin C in grapes cultivated in the South of Western Siberia. Conducted research with 12 introduced varieties and selected forms growing in the collection of the Research Institute of horticulture of Siberia M.A. Lisavenko, allowed to establish dependence of accumulation of ascorbic acid in berries on weather conditions; to allocate 5 genotypes with high content of vitamin C. It is noted that the ripening period of berries, their color, as well as the direction of use and ecological and geographical origin of varieties and selected forms did not affect the accumulation of vitamin C in the period 2014–2016.
