Background. Buckwheat is an extremely valuable groat crop in demand both in Russia and abroad. The buckwheat collection held by VIR is the largest in the world. Studying and systematizing knowledge about the conserved diversity of the genus Fagopyrum Mill. representatives cannot be efficient without switching to the use of the most detailed descriptors containing plant characters least dependent on differences in growing conditions.Materials and methods. Seventeen buckwheat cultivars from Ukraine and Belarus and two references from Russia were studied in Leningrad Province. The methodological basis of the study included the IPGRI buckwheat descriptors and personal recommendations of N. V. Fesenko. Statistical data processing was performed according to P. F. Rokitsky.Results. The cultivars formed their typical plant habitus and demonstrated good fruit setting − an average score was 3.3–4.9 out of five. The determinant stem growth was observed in 10 cultivars. The stem developed 2.7−6.7 generative nodes and 4–6 vegetative ones, while 1.9–4.7 generative and 0.8−2.3 vegetative nodes were formed on the two upper branches.Conclusion. The study confirmed that medium-ripening buckwheat can be grown in Leningrad Province. The modal value of the number of vegetative nodes for the studied cultivars was 4−5, which is an indicator of intermediate ripening. The results of studying the metamerism of the stem and the two upper branches, expressed by modal values, were recorded in the “agricultural fitness” passport for the tested cultivars as follows: determinant stem; branching zone 4+1+2; fruit-forming zone 3+3+3; average score of fruit formation 4.8. The presented data format most fully characterizes a cultivar in terms of the potential of its earliness and productivity. Depending on the task, indicators for the main stem or for the two upper branches can be used. Recording values in the form of a formula is convenient and does not imply any other meanings.

Like other postmodern structures, post-industrial labour markets display more frequent and rapid changes and higher unpredictability. In these conditions, the world of work is less capable in providing individuals stable signals for the construction of their behaviours. This paper aims to examine both macro and micro factors that shape labour market participation and expectations related to employment outcomes. We explore statistical data from the World Values Survey Wave 7 (2017-2020) collected from almost seventy thousands individuals around the world. Focusing on subjective evaluations of expected employment outcomes, our results are relevant for better understanding labour market participation from a postmodern perspective.

The paper deals with the peculiarities of the biological characteristics of the most important fruit crops of temperate climates - apple and pear (Rosaceae family, subfamily Maloideae), taking into account the world, national and regional cultivation. Both cultures are characterized by significant food and commodity value, have some differences in the chemical composition of the fruit, including the leading components of the mass and biologically active substances, which determine the peculiarities of their use in the human diet. In both global and national fruit-growing, pears play a secondary role compared to apple, giving way to the number of varieties, the volume of production and the areas occupied. Based on the analysis of available statistical data of the FAO database, the dynamics of changes from 1990 to 2016 of the world production of apple and pear fruits with visualization on the continents, identifying world leaders and major trends are considered. For the USSR (from 1962 to 1990) and in Russian Federation (from 1992 to 2016) the paper presents a picture of changes in the volume of fruit production, discusses the status of fruit production in the country. The features of the historical development and current state of fruit growing in the Samara Region and prospects are discussed.

At present it is very actual in vegetable growing the development of highly effective and ecologically safe methods for increasing yields and plant resistance to unfavorable growth conditions. One of these methods is grafting. The goal of the study was to learn the influence of the rootstock on the characteristics of the growth, development and yield of cucumber. Research was conducted in 2015-2016 in greenhouse in spring-summer period in Armenia. As a scions was used cucumber variety Nazrvan, which was grafted on 5 pumpkin rootstocks (VI033637, VI03338, VI03364, VI040903, VI056328) from the collection of the World Vegetable Center (WVC). The grafting was carried out according to the standard method. When the VI033637 rootstock was used, flowering started 5 days earlier than the ungrafted plants, while when grafted on VI040903, the fruits ripened 6.2 days earlier. High increase of early yield (33.3%) received when used both above mentioned rootstocks. VI033638 – 4.1 kg/m2 and VI033664- 9.9 kg/m2 samples provided high increase of the total yield. For all the types of rootstocks the grafted plants of cucumber surpass the non-grafted ones by height from 4.7 % to 21.7%, by marketability of fruits from 5% to 14% and by fruit mass from 15 gr to 45 g. At the beginning of fruit-setting of cucumber plants the number of female flowers increased from 27% to 63% depending on the rootstock sample. The amount of dry substances in all grafted plants has increased by 4.4-8.8% and the amount of vitamin C by 1.8-9.2%. As a result of research carried out by us, perspective rootstocks (VIO33638 and VIO33664) are identified by a set of economically valuable characteristics which are recommended for applying in the further investigation and breeding activities and in production of grafted plants.

Introduction. Parasitic diseases are common and pose threats to the health and lives of people around the world. Globally improving sanitary conditions also do not provide a sufficient method of preventing the parasitic infections that trigger them. Statistical data show a huge rate of parasitism in the world and a very large share of parasitic diseases in the number of deaths. Worms among pre-school children are quite common to a certain extent, and factors that favor them ? if properly identified, can be significantly reduced. This paper presents the frequency of occurrence of worms in this age range compared to statistical data and a list of factors predisposing the occurrence of these diseases. Aim. The aim of the study was to assess the frequency and predisposing factors for the occurrence of helminthia among children in pre-school age in Poland. Material and methods. An original questionnaire was used to conduct the research. Results. The frequency of occurrence of worms reaches about 10% of confirmed infections. The most common prevalence among children is oatosis. The most important factors predisposing to parasitic worms infection are: inadequate personal hygiene, inadequate food hygiene and its preparation, the impact of places with higher risk of infection (sandpits, playgrounds, kindergartens, nurseries, orphanages). Invasions, when the massiveness of parasite invasions is not large enough, often goes asymptomatically ? that is why the parent's perceptiveness and knowledge about the basic symptoms of the most common worms play a key role. The level of parents’ knowledge and awareness of the risk of being infected with parasitic worms is high. Most of the parents surveyed correctly diagnosed symptoms performed tests for the presence of parasites in the body of their children. Conclusions. Elimination of predisposing factors significantly minimizes the occurrence of helminthiasis.
