Abstract
In this research, the effect of using different concentrations of sodium selenate (0, 0.1, 3, 5 and 10 mg/l) in a hydroponic culture under a low greenhouse temperature on some physiological characteristics of Dorema aucheri, a perennial medicinal plant from the Apiaceae family, was studied. The use of selenium at a concentration of 10 mg/l caused a decrease in the dry weight of shoots and roots in hydroponic cultivation conditions. But the application of 0.1 and 3 mg of selenium in hydroponic cultivation not only did not cause a decrease in plant growth, but also led to an increase in biomass in the shoots. Selenium was able to increase the activity of phenylalanine ammonia-lyase and increase the concentration of phenols as antioxidant compounds in the shoots. The results of this research showed that selenium improves the growth of shoots, the amount of selenium and phenol in this medicinal plant.
