Salinity is one of the most serious environmental stresses at the irrigated areas that causes problems for the plants and soil. Kochia scoparia is an annual plant of the Chenopodiaceae family, which can be a valuable source of forage growth using saline water. Salinity changes many traits and processes, including the amount of chlorophyll a and b, activity of antioxidant enzymes, protein content, and concentration of sodium and potassium in the plant. An experiment was performed with two salinity levels of 100 and 300 mM on Kochia scoparia. Among the measured traits, the levels of chlorophyll a, b, peroxidase and catalase specific enzyme activity, and protein content were not affected by salinity. In contrast, this plant limited sodium Influx and the amount entered accumulated in the stem. Also, the study results showed that potassium concentration in this plant significantly increased in the stem. The results of other studies indicate that potassium plays an important role in tolerance to salinity. Therefore, potassium has a function in tolerance to salinity in this plant.
