Comparative analysis of integrated antioxidant activity of inflorescences of Calendula officinalis l. Plants grown in the conditions of precarpathian area on the effect of growth biostimulants
Journal Title: Біоресурси і природокористування [Biological Resources and Nature Management] - Year 2018, Vol 10, Issue 1
Abstract
The results of the study of action of plant growth biostimulants “Vermybiomah”, “Vermystym” and “Vermyiodis” on integral antioxidant activity of inflorescences of Calendula officinalis L. plants of the sort “Polova krasunia” grown on sodpodzolic soils of the Precarpathian zone of Ukraine. Antioxidant activity was determined potentiometrically using neurotransmitter system modified in research by the authors, based on methods of Brainin and Aronbayev and his co-workers. It is shown that the applying of growth biostimulants in the cultivation of C. officinalis boosted (р ≤ 0,05) the antioxidant activity of plants comparing with the control. Plants grown under the action of the “Vermybiomah” biostimulant are characterized by the highest integral antioxidant activity. The action of biostimulants is realized more under stressful conditions. It has been established that inflorescence ethanolic extracts of C. officinalis are characterized by higher antioxidant activity in 1,5-1,6 times comparing with water.
