Abstract In the literature there is very little information about fruiting, growth activity of various hawthorn species. Therefore, a comprehensive study of hawthorns is necessary in order to improve the health and living conditions in cities, as well as to obtain the highest quality harvest of fruits with valuable traits. The article presents data on the development of phases of vegetation of elite hawthorn seedlings using natural, improved vase-like and sparse-tiered crown forms in the Central Black Earth Region. It was found that the greatest annual growth of shoots was observed in the elite seedling Michurinsky Dessertniy with an improved vase-like crown shape. The largest fruits were obtained from an improved vase-like crown shape of hawthorn trees, (Karamelka, 3.7 g; Tambovskiy Volk, 3.4 g).

Physical development (RF) is one of the main indicators of health status, largely due to hereditary factors, depends on the living conditions and upbringing, social and environmental factors [1,2,3,4]. This is especially important for children and adolescents in the process of growth and development. At the present stage of scientific research of RF in pediatrics, there is a transition from the analysis of average RF indicators to a personalized assessment [5,6].

Обґрунтовано необхідність всебічного вивчення та вирощування енергетичних культур на маргінальних землях в умовах України для отримання біопалива. Наведено біолого-морфологічну характеристику та ілюстративний матеріал енергетичних культур з родини тонконогових. Розуміння морфолого-біологічних особливостей та відношення енергетичних культур до умов навколишнього середовище дасть змогу раціонально розміщувати їх у певних ґрунтово-кліматичних зонах України, підбирати оптимальні елементи технології вирощування. Це забезпечить умови, близькі до сприятливих для росту і розвитку рослин, та дозволить отримувати велику, енергоємну фітомасу. Визначено, що найбільшу врожайність сухої маси формує арундо тростинний та міскантус гігантський, меншу – сорго багаторічне та просо прутоподібне за багаторічного циклу вирощування в ґрунтово-кліматичних умовах, що відповідають їх біологічним особливостям. Урожай фітосировини енергетичних культур доцільно використати для виробництва біопалив та отримання енергії. The article substantiates the necessity of comprehensive study and cultivation of energy crops on marginal lands in the conditions of Ukraine for obtaining biofuel. Biological and morphological characteristics and illustrative material of energy cultures from the family of fine-toned ones are presented. Understanding the morphological and biological features and the ratio of energy crops to environmental conditions will allow them to be placed rationally in certain soil and climatic zones of Ukraine, and to select the optimal elements of growing technology. This will ensure conditions close to those favorable for the growth and development of plants, and will allow obtaining a large, energy-intensive phytomass. The harvest of the phytocoagulants of energy crops is expedient for use in the production of biofuel and energy production.

Abstract Phenological observations are one of the methods for studying the reaction of introduced species to new conditions and subsequent introduction into regional phytocenoses. This research wants to assess growth and development of Abies alba Mill., currentlyexotic in the Central Black Earth region of Russia. Seeds, obtained from individuals growing in the natural range (the Carpathians) in 1987 were sown in the university nursery. Then five-year-old seedlings were planted in the University arboretum. At the age of 22 the arboretum habitat was inferior to natural analogues. Phenological observations of bud opening and formation of annual growth coincide with the beginning of the growing season in natural plantings. High rates of seed germination (80%), high annual growth rates of seedlings (and transplanted plant) determined final success of silver fir in forest-steppe conditions. Precipitation has a dominant influence on growth and development, as shown by the correlation analysis between climate and growth, despite the fact that the species is drought-resistant in natural habitats. The study emphasizes the factors that control growth and development of silver fir. The use of this method of sowing is ecologically sound, which can further improve the success of species adaptation to the individual conditions of regional phytocenoses.

Parenting has a very important role in the growth and development of children. This paper examines the application of parenting education for Indonesians abroad. This activity involved 14 participants from the Indonesian School of Davao, Philippines. The method used is Participatory Action Research (PAR), which is carried out in a participatory manner with the aim of encouraging changes in the living conditions of participants for the better. The implementation of parenting education in the digital era uses synchronous modes through video conference platforms and asynchronous through the use of websites. The results of this activity showed a positive response from the participants and shared perceptions regarding the importance of care in families and schools, especially for the development of children's character.

Based on a comprehensive study of various written sources and ethnographic materials, this paper considers some aspects of personal hygiene of nomads, who lived in the Eurasian steppes during the 13th–15th centuries, i.e., primarily in the states of Genghis Khan and his descendants. Regarding both similar living conditions and ethnocultural situation, as well as the important role of traditions in the nomadic society of Central Asia, the data of the ethnographic sources about the everyday life of nomads during the subsequent eras (in the 16th–20th centuries) were extrapolated to the nomadic society of Genghis Khan’s states. The body hygiene procedures (associated with face, hands, and head hair) were analyzed. The main personal hygiene products (combs, scissors, mirrors, cosmetics (white paint), soap, etc.) were described. It was revealed that the hygiene culture of nomads in the Eurasian steppes developed under the influence of the following objective factors: nature and climate, economic and living conditions. In this process, the faith-related factors and the worldview were also critical, mostly in Ulus and Jochi. The hygiene knowledge and practices of all nomads were generally similar, but there were some specific features associated with their ethnocultural background.

Scilla peruviana is a bulbous plant whose distribution extends from South Africa, into Europe and Asia. It belongs to the family Liliaceae (subclass Monocotyledonae). S. peruviana is an attractive floral species with excellent commercial potential, but it does not produce many bulblets and its multiplication rate is very low. Increasing the multiplication rate, and regulation of its growth and development, cannot be achieved without knowledge of its basic patterns of ontogenesis. We studied the annual growth and development of S. peruviana, from initiation until differentiation, giving special attention to cytological changes at the apical meristem. We also investigated the cytophysiological changes occurring in scales during ontogenesis. Two generations of daughter bulbs are present in each mother bulb. Flowering of the mother bulb coincides with vegetative development of the apical meristem of the primary daughter bulb (March-April). During gradual senescence of leaves and roots of the mother bulb, the apical meristem of the primary daughter bulb undergoes a transition from vegetative to prefloral development (June). Intensive flower organ differentiation occurs in the daughter bulb during the mother bulb's rest period (July–August). Initiation of the apical meristem of the secondary daughter bulb occurs within the primary daughter bulb, which is itself enclosed within the mother bulb (August). The development of the apical meristem of a daughter bulb, from its initiation until flowering, thus occurs without interruption and takes ≈20 months. By modifying external factors such as temperature and growth regulators, we can now control time of flowering and increase the multiplication rate of S. peruviana.
