Item 10-річчю від дня заснування центру історії аграрної науки державної наукової сільськогосподарської бібліотеки НААН(2011) Писаренко, Віктор Микитович; Опара, Микола МиколайовичItem ACTIVITY OF LECTINS OF ST. JOHN’S WORT (HYPERICUM PERFORATUM L.) IN THE ONTOGENESIS(Винавництво ПНПУ ім. В.Г.Короленка, 2018-12) Семенко, Максим Васильович; Поспєлов, Сергій Вікторович; Оніпко, Валентина Володимирівна; Onipko, V. V.; Pospielov, S. V.У статті представлено результати досліджень гемаглютинуючої активності лектинів звіробою звичай- ного (Hypericum perforatum L.) в онтогенезі. Встановлено, що їх максимальна активність визначалась у період бутонізації та квітування. Високою активністю характеризувалися лектини листків протягом усього вегетаційного періоду (11,8 – 19,7 балів). У стеблах рівень аглютинінів зростав від періоду пагоноутворення (5,5 балів) до квітування (16,3 бали). В генеративних органах активність лектинів була максимальною (19,7– 23,3 бали). Зроблено висновок, що надземна частина, зібрана у період повного квітування, є джерелом аглютинінів високої біологічної активності.Item Aggregation-Induced Emission In Organic Nanoparticles: Properties And Applications: A Review(2018-06) Гранчак, В.М.; Сахно, Тамара Вікторівна; Короткова, Ірина Валентинівна; Сахно, Ю.; Кучмій, Степан ЯрославовичItem AGRO-TECHNICAL MEASURES FOR RATIONAL USE OF MOISTURE(2022) Писаренко, Віктор Микитович; Писаренко, Павло Вікторович; Піщаленко, Марина Анатоліївна; Мельничук, Віталій Васильович ; Євстаф’єва, Валентина ОлександрівнаItem AIE Based Coumarin Chromophores.

V.; Pysarenko, P. V.; Kulyk, M. I. ; Калініченко, Антоніна Володимирівна; Писаренко, Павло Вікторович; Кулик, Максим ІвановичAbstract. Enhancing the ecology security of Ukraine and other develop-ing countries is predetermined by the environmental problems of cities. It prompts studies on the contamination of city’s and adjacent water bodies. The control of blue-green algae distribution and the use of its biomass for production of the biofuels, energy, oils, medicine, etc. is one of the con-tributing factors to the well-balanced development of infrastructure of cit-ies. The intensity of the processes of eutrophication and the species com-position of the algae, which cause algal blooming, was investigated based on data of the Vorskla River in Poltava city (Ukraine). Relevant methods, statistical data of Ukrainian Environmental Service, personal observations, laboratory analysis and analytical studies were applied for the study. The comparative estimation of influence of separate biogenic and chemical substances on eutrophication processes was carried out. The approaches for prevention of processes of water bloom have been presented. The mecha-nism of using the species composition of algae as an indicator of the state of eutrophication processes was studied.Item Analysis of the state of dendroflora of park zones in Poltava concerning its its lesion by mistletoe (Viscum album L.)(2023) Pysarenko, V. M.; Pishchalenko, M. A.; Barabolia, O. V.; Krasota, O. G.; Писаренко, Віктор Микитович; Піщаленко, Марина Анатоліївна; Бараболя, Ольга Валеріївна; Красота, Олена ГригорівнаMistletoe (Viscum album L.) white is the only plant on the Earth that has a unique substance that paralyses cancer cells and simultaneously stimulates human immunity. However, despite its curative properties, mistletoe white has so far caused considerable damage to tree plantations in human settlements, acting not only as a parasitic plant, but also as a spreader of various diseases of woody plants. Mistletoe, being an inseparable component of tree plantations, both natural and urbanized ecosystems, settling on trees. Then it begins to destroy them intensively. This is why the question of protection of trees from mistletoe white is relevant at present. The purpose of the article is research the state of tree species in park zones of Poltava concerning their damage by white mistletoe (Viscum album L.). The article presents the results of the analysis of the state of the main tree species of the park zones of Poltava city of concerning their lesion by white mistletoe during 2017‒2022. According to the results of the study identified tree species, which due to their species biologo-physiological features are affected more and vice versa show greater resistance to damage by mistletoe white (Viscum album L.). Recommendations for improving the species composition of tree species in park areas of Poltava, taking into account their resistance to mistletoe white damage, have been formulated. For the first time, we studied the degree of damage to deciduous trees in the park areas of Poltava, and set the degree of damage to trees affected by white mistletoe depending on their species biology and physiology, particularly, the structure and thickness of the bark. The influence of species-specific biologic and physiological features of tree species in the park areas of Poltava on the degree of their lesion by mistletoe white has been established. The most resistant woods have been determined, which can be recommended for renewal of the species composition of the dendroflora of the park zones of the urban ecosystem.Item BIOMATERIALS, ROLE OF THEIR SURFACES AND OF HYDROXYAPATITE IN THE MAKING OF IMPLANTS(2016-04-28) Короткова, Ірина Валентинівна; Сахно, Ю.Э.Item COMPUTATION OF UV SPECTRA OF HETEROAROMATIC ORGANIC STRUCTURES IN SOLUTIONS(2015-04-23) Короткова, Ірина ВалентинівнаItem Conceptual framework for ensuring resource and environmental safety in the region(2019) Pysarenko, P.

A.; Писаренко, Павло Вікторович; Самойлік, Марина Сергіївна; Плаксієнко, Ірина Леонідівна; Колєснікова, Лариса АнатоліївнаPublication Correction of sowing quality of medicinal plants seeds with echinaceia extracts(2024) Pospielov, S. V.; Mishchenko, O. V.; Onipko, V. V.; Pospielova, G. D.; Поспєлов, Сергій Вікторович; Міщенко, Олег Вікторович; Оніпко, Валентина Володимирівна; Поспєлова, Ганна ДмитрівнаThe paper presents experimental data on the effect of echinacea extracts on the sowing qualities of medicinal herbs. The biological activity of extracts obtained from the areal part (EAP) and rhizomes with roots (ERS) of pale echinacea was investigated. The object of study was the sowing quality of the seeds of such medicinal plants as blue cornflower (Centaurea cyanus L.), purple echinacea (Echinacea purpurea (L. Moench.), pale echinacea (Echinacea pallida (Nutt.) Nutt.), St. John's wort (Hypericum perforatum L.), forest mallow (Malva sylvestris L.), which are of industrial importance for medicinal plants. The seeds were soaked in 0.01%-0.0001% solutions of extracts, under the control they were treated with water, after that they were germinated in Petri dishes by generally accepted methods according to the standards. The best results were obtained in mallow seed extracts. The solution of EAP at a concentration of 0.001% increased the energy of germination by 19.2% compared to the control, and when using ERS in all concentrations, a positive effect was obtained (by 18.2 %-23.6% to the control). Germination of variants treated with EAP solutions increased by 1.12-1.21 times, and ERS – by 1.09-1.21 times. Treatment of Echinacea purple seeds with EAP solutions was not effective, but rhizome extract treatment with roots had a positive effect on both germination energy and germination resulting 12.0%-17.3% and 8.3%-9.5% compared to the control, respectively. Similar regularities were observed in variants with the treatment of Echinacea seeds with extracts in different concentrations. The action of EAP solutions did not statistically exceed the control, but when using ERS, the results reliably exceeded the control by 10.8%-13.8% (germination energy) and by 11.0%- 17.8% (germination). Treatment of St. John's wort and cornflower seeds with extracts did not lead to changes in seed quality indicators. A general trend of greater activity of extracts in concentrations of 0.01%-0.001% was observed.Item Ecological-Agrochemical Land Evaluation and Classification under Organic Farming(2020) Горб, Олег Олександрович; Яснолоб, Ілона Олександрівна; Чайка, Тетяна ОлександрівнаItem Effect of melatonin and hydropriming on germination of aged triticale and rye seeds(2024) Kolupaev, Yu. E.; Taraban, D. A.; Kokorev, A. I.; Yastreb, T. O.; Pysarenko, V. M.; Sherstiuk, E. L.; Karpets, Yu. V.; Писаренко, Віктор Микитович; Шерстюк, Олена ЛеонідівнаThe formation of reactive oxygen species, which initiate lipid peroxidation of membranes and disruption of all membrane-associated processes, is one of the critical factors causing seed senescence and loss of germinability. Melatonin is currently considered one of the powerful antioxidant bioregulators that influence many plant functions, including their resistance to stress factors and seed germination. However, the effect of melatonin on the germination of old triticale and rye seeds has not been specifically investigated. The work aimed to study the effect of melatonin treatment and the well-known procedure of hydropriming (soaking in water with subsequent drying of seeds) on the germination of seeds of triticale ‘Raritet’ and rye ‘Pamyat Khudoerka’ with low germination capacity and the state of antioxidant system in seedlings. Hydropriming had a small but significant effect on the germination of triticale seeds at p ≤ 0.05 and significantly increased the germination of rye seeds. Melatonin treatment positively impacted both crop seed germination and significantly exceeded the effects of hydropriming. The most significant effect was observed when melatonin was used at a concentration of 20 μM. The accumulation of shoot and root biomass also increased under hydropriming and (to a greater extent) melatonin. Melatonin treatment led to a significant decrease in the generation of superoxide anion radical and the content of hydrogen peroxide and malonic dialdehyde, a product of lipid peroxidation, in seedlings of both crops. Additionally, melatonin increased the activity of superoxide dismutase and catalase in both crops. The anthocyanin content increased in the seedlings of both cereals under the influence of melatonin. The effect of hydropriming on indicators characterising the prooxidant and antioxidant balance was insignificant. A conclusion was drawn on the ability of exogenous melatonin to enhance the germination of old triticale and rye seeds and the connection of this effect with the regulation of the antioxidant system.Item EFFICIENCY OF THE APPLICATION OF FUNGICIDES IN THE PROTECTION OF WINTER WHEAT FROM DOMINANT SPOTS(2022) Поспєлова, Ганна Дмитрівна; Коваленко, Нінель Павлівна; Нечипоренко, Наталія Іванівна; Бараболя, Ольга Валеріївна; Корсун, Максим Анатолійович; Літвінов, Ігор ОлександровичPublication Evaluation of grain properties of buckwheat depending on variety(2024) Shakalii, S.

V.; Marenych, M. M.; Hanhur, V. V.; Tymoshchuk, T.; Malynka, L.; Пилипченко, Андрій Васильович; Маренич, Микола Миколайович; Гангур, Володимир ВасильовичSeed hemp can be used to produce products and restore soil fertility. The adaptive potential of cannabis varieties can be implemented by optimising their cultivation technologies. The purpose of this study was to substantiate the features of forming the productivity of cannabis varieties adapted to organic cultivation technologies. Field studies were conducted during 2019-2021 on leached chernozems. Research methods: field, laboratory, statistical and comparative calculation. The regularities of yield formation of hemp straws, fibre, and seeds depending on the genetic potential of varieties and cultivation technology were investigated. The suitability of five hemp varieties for organic cultivation was evaluated. It was established that the introduction of organic cultivation technology has a positive effect on crop productivity. With organic cultivation of Hliana and Hloba varieties, the increase in the yield of straw (0.07-0.11 t/ha) was statistically insignificant compared to inorganic technology. Cultivation of Zolotoniski 15 and Sula varieties using organic technologies increased the yield of hemp straw by 0.14 t/ha. The Lara variety showed an insignificant decrease in the straw yield. This confirmed the theory that the introduction of organic cultivation of hemp will not lead to a decrease in yields. Organic technologies for growing hemp contributed to an increase in their yield compared to the traditional one, provided that varieties were selected correctly. The best suitability for organic cultivation in terms of fibre yield was recorded in the Lara variety. The obtained results will be used to improve and introduce organic technologies for growing adapted hemp varieties, depending on the purpose of fibre or seeds.Item GENETIC DIVERSITY ANALYSIS OF WINTER WHEAT ACCESSIONS OF DIFFERENT GEOGRAPHICAL ORIGINS BY PCA(2022) Криворучко, Людмила Михайлівна; Тищенко, Володимир Миколайович; Макаова, Богдана ЄвгенівнаItem Influence of growth stimulants on photosynthetic activity of spring barley (Hordeum vulgare L.) crops(2021) Горобець, Максим Вікторович; Чайка, Тетяна Олександрівна; Короткова, Ірина Валентинівна; Писаренко, Павло Вікторович; Міщенко, Олег Вікторович; Шевніков, Микола Янаєвич; Лотиш, Ігор ІгоровичItem Morphological features of development of Strongyloides westeri (Nematoda, Rhabditida) in vitro(Regulatory Mechanism in Biosystems, 2018) Pishchalenko, M.
