Аналізуючи літературні дані, встановлено, що переважна більшість ефемероїдів, поширених на території України, перебувають під прямим чи опосередкованим впливом людини, що призводить до прискорених темпів зменшення їх чисельності. Урбаністичний фактор впливає не лише на видовий склад популяцій, але й на їх абсолютні кількісні показники. Метою досліджень було вивчення флористичного складу рослин-ефемероїдів на території ландшафтного парку місцевого значення «Немирівське Побужжя» поблизу села Гвоздів Немирівського району Вінницької області. Матеріали і методи. Вивчення флористичного складу рослин-ефемероїдів території ландшафтного парку місцевого значення «Немирівське Побужжя» проводилося експедиційно-маршрутним методом, а також випадково-регуляторним способом-закладання облікових ділянок площею 1 м2. Систематична належність рослин визначалася за допомогою визначника. Рясність видів визначалася за шкалою Гульта-Друде (з доповненням А. А. Уранова та П. Д. Ярошенко). Коефіцієнт зустрічання (%) визначали за формулою: R= a x 100 / n.
The study aimed to analyze the psycholinguistic dimension of the personal interaction of the subjects of the educational space in the conditions of the COVID-19 pandemic. For this purpose, a model was built to assess the influence of distance learning in an electronic environment or other unconscious forms on the effectiveness of school education. Through the study, the main factors influencing the effectiveness of learning at the school, class, and individual level (students, teachers, and parents) were identified and analyzed. A logical assessment framework model was created linking the resource provision of the educational distance process, organization and flow of learning processes, accessibility of the system of adaptation, and support for learning and achievement of results for students, teachers, parents, and school. The study provides an opportunity for a broader diagnosis of the effectiveness of education in the education system. It can facilitate data-driven decision-making to ensure adaptability and improve the effectiveness of the educational process to reduce inequality, ensure equal opportunities for quality education, ensure the sustainability of acquired knowledge and skills, and reduce the risk of dropping out of school in the context of the COVID-19 pandemic.
Biostimulants are the kind of "doping", due to which crops gain great vitality for crop formation. Growth stimulating drugs make a positive effect on the soil microflora, they are rapidly transformed by soil microorganisms, plant cells. The aim of the work was to substantiate scientifically the use of stimulating growth regulators –Epin-extra, Agorostimulin, Rival, and Kornevin, as the elements of soybean growing technology;to identify their effect on biological characteristics and seed productivity of the crop. The research was conducted on soybean variety Millennium. Pre-sowing experimental treatments of seeds were carried out with aqueous solutions of Epin-extra (0,025 g l), Agorostimulin (1 ml/l), Rival (1 ml/l) and Kornevin (0,5 g/l), and control – with water. During the study laboratory germination and energy of germination of seeds, and also morphometric indicators of seedlings and roots were defined. It was found that the pre-sowing treatment of soybean seeds of Millennium variety with stimulant drugs – Epin-extra (0,025 g/l), Agorostimulin (1 ml/l), Rival (1 ml/l) and Cornevin (0,5 g/l) increased seed productivity. In all variants of the experiment, both germination energy and seed germination were increased. It was found that the most effective drugs for the increase of germination energy and seed germination of Millennium soybeans are Epin-extra (0,025 g/l) and Agorostimulin (1 ml/l). Under the action of plant growth stimulators, morphometric changes occurred in soybean seedlings. The drugs affected the length of the hypocotyls in seedlings of soybean culture. Under the use of Epin-extra (0,025 g/l) the length of hypocotyls increased by 18 %, under the action of Agorostimulin (1 ml/l) – by 32 %, under Cornevin (0,5 g/l) treatment - by 41 % and after the use of the drug Rival (1 ml/l) – by 85 %. Stimulators helped to lengthen the main root of soybean seedlings. The largest indicator of the length of the main root was found under the treatment of such drugs Riaval and Agorostimulin. It was found that all studied drugs contributed to the regrowth of lateral roots in soybean seedlings, but the best effect was observed under the usage of the drug Cornevin (0,5 g/l). The significant increase in the dry weight of Millennium soybean seedlings was revealed with the use of stimulating plant growth regulators. The increase of the dry weight of soybean seedlings was detected under the pre-sowing treatment of seeds with Cornevin (by 36 %), Agrostimulin (by 50 %), and Rival (by 88 %) in comparison to the control. Pre-sowing treatment of soybean seeds leads to the increase of dry weight of roots. The best effect on the increase of dry weight of roots was found under the use of drugs Cornevin and Agrostimulin. The use of Epin-extra and Rival also led to a positive result, but not as significant as after the use of two previous drugs that were given above.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
