Abstract

Background: Burdock (Arctium lappa L.) is a widely used perennial plant in traditional medicine globally. Selenium, although non-essential for plants, is crucial for humans and animals. This study aimed to investigate the impact of foliar spraying with varying concentrations of selenium nanoparticles (0, 10, and 15 ppm) on the physiological and biochemical responses of buckwheat plants. Methods: For this purpose, the plants grown in the field environment were harvested after treatment and The effect of treatments on enzymatic (catalase, peroxidase, superoxide dismutase) and non-enzymatic (phenolic compounds, flavonoids, proline) antioxidant was examined. Findings: Results revealed that selenium nanoparticle treatments significantly influenced protein, carbohydrate content, and antioxidant activity.At the concentration of 15 ppm, the highest levels of antioxidant activity were observed in all three scavenging assays, namely DPPH, ABTS, and SO Conclusion: The findings suggested the positive effect of selenium nanoparticles on antioxidantive capacity of Arctium lappa.
