THE INFLUENCE OF PHYTOHORMONES AND MICROELEMENTS ON THE ACCUMULATION OF BIOLOGICALLY ACTIVE SUBSTANCES IN MEDIASIA MACROPHYLLA
Keywords:
Mediasia macrophylla, phytohormones, microelements, biologically active compounds, phenolic compounds, flavonoids, pigments, antioxidant activity.Abstract
The article presents the results of a study on the effect of phytohormones and microelements on the growth and accumulation of biologically active compounds (BACs) in Mediasia macrophylla, a plant endemic to Central Asia. Treatment of seeds with gibberellic and indole-3-acetic acid solutions promoted faster germination and increased plant biomass. Spectrophotometric and chromatographic analyses were conducted to determine the content of phenolic compounds, flavonoids, and photosynthetic pigments, as well as to assess the antioxidant activity of the extracts. It was found that phytohormonal stimulation increased the content of phenolic compounds up to 2785 mg/g and enhanced pigment metabolism. The obtained data confirm the effectiveness of the combined application of phytohormones and microelements in the cultivation of Mediasia macrophylla for obtaining raw materials rich in biologically active compounds.
