One of stressful factors the reducing harvest and quality of bulbs of garlic winter (Allium sativum L.) defeat is diseases of various etiology. Studying of influence of factors of the external environment and stability of a genotype on prevalence of diseases on landings of garlic winter and degree of their injuriousness in the conditions of the Moscow region was the purpose of researches; assessment of collection and selection samples of garlic winter and identification among them steady against the most economically significant diseases. Object of researches were grades and collection samples of garlic of the Federal Scientific Vegetable Center, winter from collections, and other selection institutions. Field experiments and assessment were carried out on a natural infectious background for a number of years. It is as a result established that in the conditions of the Moscow region during vegetation of a plant of garlic winter mainly are surprised mushroom diseases (mycoses) among which the dominating position is taken by fusariosis (micromycetes of the sort Fusarium spp). Defeat of garlic fusariosis is shown annually and with different intensity, depending on weather conditions. The analysis of literature and results of our researches show that number and a ratio of types of Fusarium spp. in a pathogenic complex changes in last years. The types which are earlier not noted on the culture of garlic in the Moscow region (since 2009 – F. avenacium, F. proliferatum, F. subglutinans and F. semitectum are registered; since 2017 – F. gibbosum and F. nivale). In a complex with highly aggressive types of F. solani and F. oxysporum they enhance injuriousness of fuzariosis withering and rots. Mushrooms of the sort Alternaria and other micromycetes of the sorts Stemfillium, Pythium, Embilisia, Verticillum, Cladosporium in the conditions of the Moscow region meet mainly in a complex Fusarium. Gray rot (the activator – Botrytis allii L.) it is more often shown in storage time and transportations of bulbs of garlic. These micromycetes enhance injuriousness of fusariosis and increase losses of a harvest of garlic winter, especially, in the conditions of sharp fluctuations of average daily temperatures and humidity of the soil during the different periods of vegetation. Results of long-term assessment are given in article, grades and perspective collection samples of garlic winter the steadiest against defeat with diseases in the conditions of the changing climate of a zone of Non-Black Earth Region are allocated.

Whole inshore male capelin (Mallotus villosus) were stored at −23 °C for 2 mo (C2), or 6 mo (C6) prior to thawing, beheading and eviscerating, and refreezing. Though the quality of the twice-frozen product was in both cases inferior to a once-frozen sample, it was still quite acceptable after 2 yr of refrozen storage. As expected, quality was superior in the C2 samples, but in both sets of samples taste deteriorated to a greater extent than texture. Chemical measurement of peroxide value indicated a possible development of rancidity that could not be detected by sensory analysis. Considerable lipid hydrolysis occurred, with the free fatty acids (FFA) at least doubling during storage; increases were greater in C6. In both experiments FFA production correlated with texture, taste, and with extractable protein nitrogen (EPN). Dimethylamine (DMA), trimethylamine (TMA), hypoxanthine, and EPN appeared to be good indicators of storage time and sensory quality. Key words: capelin, dimethylamine (DMA), extractable protein nitrogen (EPN), free fatty acids (FFA), hypoxanthine, peroxide value, refrozen storage, taste, texture, trimethylamine

Пищевая ценность свеклы столовой определяется высоким содержанием сахаров, своеобразным составом азотистых веществ. Эта культура – источник натурального красителя бетанина, который обладает антиканцерогенным, антибактериальным и противовирусным действием на организм человека. В статье представлены результаты изучения биохимических качеств корнеплодов свеклы столовой. Исследования проводились в период 2014–2019 годов на шести сортах свеклы столовой селекции Агрохолдинга «Поиск». За стандарт взяты широко распространенные образцы отечественной и голландской селекции Бордо 237 (ВНИИССОК) и F1 Пабло (Bejo), районированные во всех регионах РФ. Полевые опыты выполнены по единой методике на базе ВНИИО – филиала ФГБНУ ФНЦО в Раменском районе Московской области. Почва опытного участка относится к типу аллювиальных луговых, среднесуглинистая, насыщенная, влагоемкая. Погодные условия наиболее благоприятно для роста и развития растений свеклы столовой складывались в периоды вегетации 2014–2017 годов. Особенность погодных условий 2018–2019 годов – неравномерное выпадение осадков, что повлияло на время прорастания семян. Дефицит влаги в период вегетации компенсировали поливами методом дождевания, поддерживая НВ на уровне 80–85%. Наибольшее количество сухого вещества накапливает сорт Русская односемянная – 18,4%, что соответствует уровню стандарта Бордо 237. Высокое содержание сахаров свойственно сорту Креолка – 10,7%, и превосходит стандарты на 1,8%. Образцы, восприимчивые к заболеваниям листовой розетки во время вегетации культуры – Эфиопка и F1  Пабло накапливают меньше пигмента бетанина. Биохимические качества корнеплодов сорта Креолка больше сопряжены с его генотипом. Накопление нитратов у образцов крайне подвержено условиям года. Более чем в десять раз изменяется содержание нитратов в зависимости от года у сортов Славянка, Русская односемянная, Креолка и Бордо 237. Выход товарной продукции после шести месяцев хранения по изучаемым образцам колебался от 49,1 до 91,4%. Отличную сохранность на уровне стандартов – свыше 85% показал сорт Русская односемянная. The nutritional value of table beets is determined by a high content of sugars, a peculiar composition of nitrogenous substances. This culture is a source of the natural dye betanin, which has anti-carcinogenic, antibacterial and antiviral effects on the human body. The article presents the results of a study of biochemical qualities of root crops of table beet. Research was conducted in the period 2014–2019 on 6 varieties of beet of table selection of the Poisk Agrо Holding. Widespread samples of domestic and Dutch breeding Bordo 237 (FSCVG) and Pablo F1 (Bejo), zoned in all regions of the Russian Federation, were taken as a standard. Field experiments were performed according to a single methodology on the basis of ARRIVG – branch of FSCVG. The soil of the experimental site belongs to the type of alluvial meadow, medium-loamy, saturated, moisture-intensive. Weather conditions were most favorable for the growth and development of table beet plants during the growing season of 2014–2017. A feature of the weather conditions of 2018-2019 was uneven precipitation, which affected the time of germination of seeds. The lack of moisture during the growing season was compensated by irrigation by sprinkling, maintaining the HB at the level of 80–85%. The largest amount of dry matter accumulates Russian single-seeded variety – 18.4%, which corresponds to the level of the standard Bordeaux 237. High sugar content is characteristic of the Creole variety – 10.7%, and exceeds the standards by 1.8%. Samples that are susceptible to diseases of the leaf rosette during the growing season of the culture-Ethiopian and F1Pablo accumulate less of the pigment betanin. The biochemical qualities of Creole root crops are more associated with its genotype. The accumulation of nitrates in samples is highly susceptible to the conditions of the year. The nitrate content varies more than 10 times depending on the year in the varieties Slavyanka, Russian single-seeded, Creole and Bordo 237. The output of marketable products after 6 months of storage in the studied samples ranged from 49.1 to 91.4%. Excellent preservation at the level of standards – over 85% showed the Russian single-seeded variety.

Triticale (×Triticosecale Wittmack) is a promising cereal crop that has a number of economically valuable properties that are absent in wheat (Triticum aestivum L.). The research was conducted at Uman National University of Horticulture (Ukraine) in a long-term stationary experiment, founded in 1964. The aim of the work was to study the influence of long-term application of different fertilizer systems (mineral, organic and organo-mineral) on the yield and grain quality of spring triticale. It has been established that in the conditions of high air temperature and soil moisture deficit, mineral and organo-mineral fertilizer systems have an advantage. In sufficient wet conditions, all studied fertilizer systems are highly efficient. Spring triticale (Kharkiv Hlibodar variety) has a high reaction to fertilizers, as grain yield increases from 6.3–6.6 to 9.0–9.5 t ha-1 (р≤0.05). Mineral and organo-mineral fertilizer systems have the greatest effect on protein content. In conditions of sufficient moisture, all levels of mineral and organo-mineral fertilizer systems significantly increase the protein content in spring triticale grain. In arid conditions, saturation of crop rotation area with N90P90K90 (M2), N135P135K135 (M3) and Manure 9 t +N46P68K36 (OM2), Manure 13.5 t + N69P102K54 (OM3) is preferred. It should be noted that spring triticale is quite reactive with fertilizers, as the protein content increases from 13.2–14.0 to 15.2–16.0% (р≤0.05) depending on the fertilizer system. The high influence of fertilizer system and year factors on yield and protein content in triticale grain has been established. It should be noted that spring triticale grain yield varies most from the weather conditions of the growing season.

The feasibility of implementing the "4 ppm" initiative, which assumes an annual increase in organic carbon stocks of agricultural soils in the layer 0-40 cm, was estimated with the dynamic carbon model RothC in two long-term DAOS experiments in the Moscow region, conducted in neighbouring fields for 74 and 76 years. Treatments included absolute control, application of organic, mineral, organic and mineral fertilizers at increasing rates. One of the experiments showed the growth of C stocks 12‰ in the layer 0-20 cm in the first 20 years in treatments with mineral fertilization, and 17‰ with the additional application of manure in an average annual rate of 10 Mg·ha-1. The accumulation of C allowed increasing its stock by 18-25%. Still, with the subsequent decline in crop rotation productivity, there was a loss of part of the previously accumulated C. In another experiment, at close values of annual C input, there was a loss of initial C stock due to the history of land use. The crop rotation adjustment provided a 3-8 ‰ increase of soil C in the 0-20 cm layer in the first 20 years after introduction but was insufficient to match the "4 ppm" initiative. In the long term, the organic fertilizer system had an advantage over the mineral one in ensuring the stability of organic C stocks in the arable layer. However, the management of C sequestration was complicated in the non-equilibrium state of the carbon system "plant residues-organic fertilizer-soil".

The objective of this field crop study was to compare the effect of organic (cattle manure, off-season cover crop) and mineral N (NH4NO3; 0, 50, 100° 150 kg N ha−1) fertilizers on (i) gluten-starch interaction, and (ii) rheological properties of winter wheat dough. Data were collected from the long-term field experiment located in the Baltic Sea region (58°22’ N, 26°40’ E) in years 2013–2017. The amount of minuppueral N 150 kg ha–1 applied in two parts before flowering ensured higher gluten content (31 ± 3.3%) and dough quality (81 ± 7.4 mm) due to more positive interactions between gluten proteins and starch granules. The quality of dough was more variable in organic treatments (ranged up to 33%) because the availability of organic N was more variable and sensitivity to the weather conditions was higher. The mean variability of different dough properties over trial years under organic treatments was 1.4–2.0 times higher than in the treatment with 150 kg N ha−1.

Introduction. The problem of long-term and prognostic assessment of the terms of spring floods on rivers is relevant in hydrological investigations. Due to climate warming, the flood tides shifted to early dates or the beginning of the calendar year. The purpose is to analyze the long-term passage of spring floods and to carry out their spatial mapping forecasting on the Dnieper (within Ukraine). Methods. Investigation of the dynamics of long-term changes in the timing of spring floods and the use of the forecast method based on the meteorological forecast of ten-day air temperature in the winter-spring season in the Dnieper basin. Results. The method of forecasting the dates of starting and passing the maximum water discharge (levels) is based on the regional equations of the forecast scheme and allows to make a preliminary estimation of flood terms each year, regardless of the availability of meteorological observations. Assessment of the forecasting methodology allows to recommend it as a consultation, and the earliness of forecast varies depending on the geographical location of the catchments and the current weather conditions of a particular spring. Conclusion. The methodology was implemented on the example of spring floods 2017-2018. The overall forecasts were satisfactory, but the quality of the forecasts was affected by the non-simultaneous terms of the spring flood formation in the Dnieper basin. The prognostic probabilities of the dates of spring flood allow characterizing the frequency of their occurrence over many years. On the example of the 2017-2018 spring flood, the rivers of the Dnieper basin found that, in a changing climate, floods can be shifted to earlier and later ones.

AbstractData from several field experiments support the existence of a trade-off between number and quality of offspring. However, long term effects of brood size on fitness related traits of offspring have been a relatively neglected area of research. In a laboratory experiment the effect of manipulated brood size on subsequent competitive ability of adult offspring was investigated. Zebra finches, Taeniopygia guttata, were reared in small or large broods and young were exchanged in such a way that natural siblings from different rearing conditions could be compared. Competitive behaviour was assessed in two different contexts: competition for food (both sexes tested) and competition for mates (only males tested). There was no significant difference between males from small and large broods in number of succesfull attacks (after which the other male moved away) during male-male aggressive interactions provoked by the presentation of a female in an adjacent cage. Nor did brood size affect latency to eat, time spent eating or success at displacing the other bird from the feeder during food competition tests. The results thus suggest consistently that later competitive ability of offspring is not affected by brood size in this species.

Autologous fat grafting has now been extensively and successfully performed for more than two decades. Although most adipose grafts and adipose-derived MSC therapies are done with fresh tissue, cryopreservation of tissue allows for much greater flexibility of use. Over the course of five years, 194 cryopreserved adipose samples were thawed and then returned to the collecting physician for subsequent autologous applications. Samples were stored with a mean cryogenic storage time of 9.5 months, with some samples being stored as long as 44 months. The volumes of tissue stored varied from 12 cc to as large as 960 cc. Upon thawing, the volume of recovered whole adipose tissue averaged 67% of the original amount stored for all samples, while the samples that were stored for longer than one year averaged 71%. Recovery was not found to be a function of length of time in cryopreservation. No significant relationship was found between tissue recovery and patient age. While an average recovery of 67% of volume frozen indicates that the use of banked and thawed tissue requires a larger amount of sample to be taken from the patient initially, an experienced clinician easily accomplishes this requirement. As cryopreservation of adipose tissue becomes more commonplace, physicians will find it helpful to know the amount and quality of tissue that will be available after thawing procedures.
