In the Moscow region, for a long-term species of bows in winter, a complex of limiting factors determines their winter hardiness. To characterize the period from November to March 2014-2017. The winter severity index (Woz) was calculated on a scale from 0 to 10 points (0 very soft, 10 very severe). The severity of winter in 2014-2015 was 2.91 points, 20152016 3.14 points, 2016-2017 4.75 points. The average percentage of overwintered plants for each sample was determined by the ratio of the number of living plants to the number of dead. Many varieties of welch onion were not sufficiently winter-hardy, including Red, Snowdrop, Russian size, Handsome, April, Russian winter. Stable high 100% winter hardiness showed a variety of welch onion Green feathers. From the studied 71 species and 194 samples of bows of perennial different ecological and geographical origin under the conditions of the Moscow region in the subgenus Amerallium plants A. neapolitanum Cirillo (Molium section) and A. ursinum L. (section Arctoprasum), and also in the subgenus Nectaroscordum A. bulgaricum plants (Janka) Prodбn (section Nectaroscordum (Lindl.) Gren. & Godr.) in the winter of 2014-2015 died completely. Winter in 2016-2017 years in the subgenus Rhizirideum, section Rhizirideum G. Don ex Koch A. senescens L. plants overwintered 75%, A. nutans L. – 90-95% depending on the sample, A. stellarianum Willd. 15 %. In subgenus Melanocrommyum, section Melanocrommyum Webb & Berthel. s.s. plants A. cyrillii Ten. overwintered 75%. In the subgenus Butomissa, sections Butomissa (Salisb.) Kamelin plants Allium odorum L. overwintered 86-93% depending on the sample. In the subgenus Cepa, the section Schoenoprasum Dum. plants A. ledebourianum Schult. & Schult. f. overwintered 75%.

AbstractThe variability of occurrence of snow cover and the impact of atmospheric circulation on the snow cover occurrence in the period 1966/1967–2019/2020 in Poznań (Poland) have been examined. The implementation of the primary study objective covers the comprehensive analysis of the winter snow and thermal conditions using various indicators. This paper is based on daily data from the years 1966–2020 concerning the winter period. Winters in Poznań are highly variable and differentiated, considering the duration of particular seasons, number of days with snow cover, mean snow cover thickness, winter snowiness coefficient, or winter severity index. Negative trends concerning days with snow cover total snow cover depth winter snowiness coefficient and winter severity index in Poznań prove statistically significant. A higher probability of occurrence of snow cover was determined during cyclonic than anticyclonic circulation. The westerly and northerly types especially favoured the occurrence of days with snow cover. The increase of snow cover was associated with the northerly inflow mainly. Westerly types of circulation caused the decrease of snow cover predominantly.

The study of the frost resistance was carried out in 2017–2019 on the basis of the Laboratory of Physiology of Fruit Plant Resistance, Russian Research Institute for Fruit Crop Breeding. Strawberry cultivars of different ecological and geographical origin (‘Kokinskaya Rannia’, ‘Rosinka’, ‘Solovushka’, ‘Tzaritza’, ‘Urozhaynaya TzGL’ – Russia; ‘Sara’ – Sweden; ‘Alba’, ‘Marmolada’ – Italy; ‘Korona’, ‘Sonata’ – Holland) were used as experimental material. The frosts resistance of strawberry varieties was studied in the laboratory conditions was used by artificial freezing. A model of strawberry plant selection was developed to determine the main components of winter hardiness. On the basis of preparation of plant samples for modeling of damaging factors of the winter period, storage conditions of experimental plants were developed. Plant hardening and modeling of damaging factors of the winter period were carried out with the additional modification for strawberries. As a result of the artificial freezing, the damage to the tissues of rhizome and apical buds of shoots of strawberry varieties of different ecological and geographical origin were evaluated in early winter period and during thaws in winter. It was determined that the decrease in the temperature to -15°C at the end of November did not cause irreversible damage to the strawberry varieties. The decrease in the temperature to -20°C in early December increased the damage to the studied strawberry varieties. During the winter it was determined that the strawberry response to the thaw increased by the end of the winter period. The decrease in frost resistance is primarily due to the resumption of growth processes under the influence of positive temperatures. As a result of determining the components of winter hardiness, the varieties Solovushaka, Tzaritza (Russia), Sara (Sweden) and Korona (Holland) showed the greatest potential of frost resistance.

The results of researches of winter hardiness cultivars and selected forms of raspberry in the field and laboratory conditions have been presented. The study was conducted in FSBSI All-Russia STIHNG and its Kokino Base Station (Bryansk region). The objects of research were 20 cultivars and 10 selected forms of raspberry of various genetic-geographical origin. The main purpose of the work was to study the resistance of cultivars and selected forms of raspberry to temperature stress factors of the winter period and the identification of the most winter-hardy genotypes. As a result, it was established that the cultivars Peresvet, Balzam, Beglyanka, Rubin Bryanski and nine selected forms showed high field winter hardiness. When modeling damaging winter factors, it was revealed, that the cultivars Gusar, Lazarevskaya, Volnitsa, Meteor and selected forms 32-16-1, 1-15-1, 1-2-2, 6-12-2 well tolerated frost-35C in the middle of winter. The cultivars Gusar, Meteor, Volnitsa and selected forms 32-16-1, 1-4-2, 1-15-1, 1-2-2, 2-12-1 distinguished by reliable resistance to component III of winter hardiness. Among the studied raspberry assortment, the genotypes with a high level of bud resistance to IV component of winter hardiness were not revealed.

Development of low-growing varieties is one of the prioritized directions in groups selection. Solution of excessive growth in the selection can be solved in today’s conditions by two means: on a polygenic and on a monogenic level. Up until recently such work was performed by research institutes of horticulture in the U.S.S.R. and Russian Federation only on the polygenic level. The analysis is performed for the data of 17 summer studies on the development of complex donors of monogenic determined dwarfness (gene D), high winter hardiness, group fungal disease resistance (scab, leaf spot and Septoria blight) and bright red coloration of pear fruits (gene C). On the first stage of these studies the issue of the development of population of hybrid dwarf types with high adaptive potential in the conditions of the Central Black Earth region of Russia was solved based on a hybridization of the donors of high winter hardiness and fungal disease resistance with the donors of monogenic determined dwarfness which were the descendants of 4th generation of the NainVert variety. As a result, several complex donors were selected. Its use in long-term pear selection programs would make sorting process possible on earlier stages of the ontogenesis and thanks to that would make it possible to halve the size of hybrid funds. Brief description of the complex donors is given.

The aim of our research was to analyze the composition of an ampelographic collection of the V. Ye. Tairov Institute of Viticulture and Winemaking by geographical origin of varieties, application, ripening period, berry color, flavor profile, seed development, winter hardiness and frost tolerance, and resistance to major fungal diseases. To enrich the database of varieties – sources and donors of valuable traits via analysis of data on expression of adaptability and performance characteristics. Results and Discussion. At present, there are 736 varieties in the ampelographic collection of the V. Ye. Tairov Institute of Viticulture and Winemaking. The largest portion contains Ukrainian, Russian and Moldavian varieties. More than half (59 %) are table varieties; one third (31%) are wine ones; and 10 % are universal varieties and varieties that are still being studied. As to the ripening period, a group of early-ripening, mainly table varieties (23 %), stands out. The most numerous portions of the collection are mid- and late-ripening varieties (17 % each). The percentages of early-middle and mid-late varieties are similar (11 and 12 %, respectively). Among the berry colors, white and its variations (yellow, yellow-green, amber, etc.) account for 44 %; black – for 23 %; and pink – for 6 % of the collection accessions. There are varieties with red-violet, white-pink, yellow-pink, pale red or bright red berries. Significant diversity was also found in flavor characteristics of the collection accessions. Even in the largest group with so-called “simple taste” (86 % of the collection accessions), varieties with bright prune, solanum, flower, honey and other aromas were found. Varieties with muscat flavor remain in high demand on the market. It was found in 12.5 % of varieties, which can be used in further breeding process. The collection contains 7 % of seedless varieties. Among the collection accessions with their diverse genetic and geographical origin, 82 % have low winter hardiness and frost tolerance and are damaged even at –20 – 21oC. They are mainly European varieties without genetically determined mechanisms of protection against low temperatures and overwintering conditions. 17.9 % of the collection accessions vary from relatively frost tolerant (−22 – 24oC) to frost tolerant (−26–28oC). More than half of the collection accessions (64.5 % ) are susceptible to fungal diseases, since they derive from non-resistant varieties. They are mainly intraspecific Vitis vinifera L. varieties. They are used in crosses as donors of product quality characteristics. A third of varieties showed relative resistance to diseases (6–7 points on a 9-point scale (Bankovska, 2007)). They are widely used in further crosses to obtain genotypes with genetically determined disease resistance. Conclusions. The observations and analysis of adaptive and productive characteristics of 735 collection varieties of the V. Ye. Tairov Institute of Viticulture and Winemaking have resulted in enrichment of the database both with introduced and with our own valuable varieties - donors.

There are few long-term nutritional studies in subjects undergoing bariatric surgery that have assessed weight regain and nutritional deficiencies. In this study, we report data 8 years after surgery on weight loss, use of dietary supplements and deficit of micronutrients in a cohort of patients from five centres in central and northern Italy. The study group consisted of 52 subjects (age: 38.1 ± 10.6 y, 42 females): 16 patients had Roux-en-Y gastric bypass (RYGB), 25 patients had sleeve gastrectomy (SG) and 11 subjects had adjustable gastric banding (AGB). All three bariatric procedures led to sustained weight loss: the average percentage excess weight loss, defined as weight loss divided by excess weight based on ideal body weight, was 60.6% ± 32.3. Despite good adherence to prescribed supplements, 80.7% of subjects (72.7%, AGB; 76.7%, SG; 93.8 %, RYGB) reported at least one nutritional deficiency: iron (F 64.3% vs. M 30%), vitamin B12 (F 16.6% vs. M 10%), calcium (F 33.3% vs. M 0%) and vitamin D (F 38.1% vs. M 60%). Long-term nutritional deficiencies were greater than the general population among men for iron and among women for vitamin B12.

Flooding normally occurs during periods of excessive precipitation or thawing in the winter period (ice jam). Flooding is typically accompanied by an increase in river discharge. This paper presents a statistical model for the prediction and explanation of the water discharge time series using an example from the Schoharie Creek, New York (one of the principal tributaries of the Mohawk River). It is developed with a view to wider application in similar water basins. In this study a statistical methodology for the decomposition of the time series is used. The Kolmogorov-Zurbenko filter is used for the decomposition of the hydrological and climatic time series into the seasonal and the long and the short term component. We analyze the time series of the water discharge by using a summer and a winter model. The explanation of the water discharge has been improved up to 81%. The results show that as water discharge increases in the long term then the water table replenishes, and in the seasonal term it depletes. In the short term, the groundwater drops during the winter period, and it rises during the summer period. This methodology can be applied for the prediction of the water discharge at multiple sites.
