“…Обговорення результатів дослідження. Аналізуючи отримані результати, встановлено, що вони підтверджують дослідження, проведені вченими [18,19] В результаті досліджень встановлено, що алелопатична активність пелюсток і суміші генеративних органів порівняно із контролем мають позитивну алелопатичну дію (5,2 ; 22,8 та 30,5%). Однак спільна дія пелюсток і приймочок маточок має незначну інгібуючу дію (-1,9%).…”

“…Враховуючи можливість вирощувати C. sativus в Північному Причорномор'ї, постає необхідність дослідження алелопатичної активності рослин та встановлення місця культури в агрофітоценозі України. Відомо, що при вирощуванні в Ірані C. sativus може рости на одному місці до 12 років, але рекомендують вирощувати протягом 5-6 років на одному місці, після чого урожайність знижується [18,19].…”

The purpose of the article is to study the allelopathic activity of generative organs of Crocus sativus L. (saffron crocus) as a new promising crop for the agrophytocenoses of Ukraine, which has valuable properties and it is used in various industries: the official pharmacopoeia for the treatment of nervous disorders, cancer and the food industry as a valuable spice and organic dye. For safe cultivation of the crop and prevention of soil fatigue, it is necessary to study the effect of water-soluble flower secretions that remain in the fields after removing the stigmas of pistils. Materials and methods. The materials for the research were plants of Crocus sativus, grown on the plots of the Mykolaiv National Agrarian University during 2019-2020. The research was conducted in 2020 on the basis of university laboratories. The collection of flowers and the study of allelopathic activity of water-soluble secretions were carried out in accordance with generally accepted methods. Results and discussion. As a result of our research, it was found that water-soluble secretions of Crocus sativus flowers and their parts at different concentrations stimulated the energy of seed germination and the growth of single-day seedlings L. sativum. There was a lower germination energy in the "perianth+pistil" variant at a filtrate concentration of 0.02%. With an increase in the filtrate concentration, there was a decrease in root growth for all variants except the "perianth+pistil" variant: the lowest decrease was at a concentration of 0.09 and the highest one was at 0.02 compared to the control (7.58 and 4.77%). The coefficient of variation in the root length of one-day seedlings of the test plant had a very high coefficient of variation (>40%) for all variants, except for the "perianth+pistil" variant, which was characterized by a high indicator. For perianth secretions, when the concentration increased, allelopathic activity increased from insignificant inhibitory activity (-0.98) up to stimulating activity (35.70). Other variants were characterized by an inhibitory effect. Conclusion. The growth of allelopathic activity of water-soluble secretions of flower elements at different concentrations can be depicted in the following order: for the perianth it was 0.01<0.02<0.09; for the flower it was 0.01<0.02>0.09; for the perianth and stamen it was 0.01<0.02>0.09, for the perianth with a pistil it was 0.01<0.02>0.09. The highest indicators of allelopathic activity of water-soluble secretions of flowers detected at a concentration of 0.02%

Today the use of silver nanoparticles is becoming increasingly widespread due to their wide applications as antimicrobial agent. Green synthesis of silver nanoparticles (SNPs) using the petal extract of saffron (Crocus sativus) as a reducing agent from 5 mM AgNO 3 has been investigated in this work. Diverse petal extracts quantities and reaction times were used for the synthesis of SNPs. The resulting SNPs were characterized by means of UV-Vis, XRD and FTIR techniques. SNPs were synthesized rapidly within 30 min of incubation period and synthesized SNPs showed an absorption peak at 380-400 nm in the UV-Vis spectrum. XRD spectrum confirmed the formation of metallic silver, too. Green synthesized SNPs were used as antimicrobial agent against three bacterial genera of Bacillus, Pseudomonas and Acinetobacter which contaminate preservative solution of cutflowers, too. According to the results biosynthesized SNPs using saffron petals successfully controlled these bacteria and have made them promising candidates as new generation of antimicrobials. This route is rapid, simple without any hazardous chemicals and economical to synthesized SNPs.
