Abstract: (17 Views)
This experiment was conducted in 2022 to evaluate selenium and biochar application on reducing oxidative stress caused by cadmium in savory (Satureja hortensis L.) as a factorial experiment in a completely randomized design with three replications. The research treatments included cadmium at three levels (0 (control), 10, and 20 mg.kg-1 soil), biochar at two levels (0 and 5% of pot v/v), and selenium at three levels (0, 5, and 10 mg.1-1). The results of the present study indicated that biochar and selenium interaction increased total phenol, and cadmium at medium levels had the greatest effect on increasing total phenol. The interaction application of biochar and selenium 10 mg.1-1 and cadmium 10 mg.kg-1 as well as biochar and selenium 5 mg.1-1 and cadmium 10 mg.kg-1 increased total phenols by 49.23 and 49.53%, respectively, compared to the control. Based on the results of the comparison of the average interaction effect of cadmium and selenium, cadmium 10 mg.kg-1 and selenium control, as well as cadmium control and selenium 10 mg.1-1 increased flavonoids by 50.21% and 48.66% compared to the cadmium 20 mg.kg-1 and selenium control treatments. The highest superoxide dismutase enzyme activity, with 9 enzyme units per mg protein, was obtained in the treatment of 20 mg.kg-1 cadmium without biochar and selenium application. Selenium and biochar reduced the activity of the superoxide dismutase enzyme in cadmium-stressed treatments. In general, simultaneous application of 5% v/v biochar with 5-10 mg.l-1 selenium was an important modifier of cadmium stress (moderate stress) in summer savory.
