Abstract

Wheat (Triticum aestivum) is an important grains plant that can sustain food security and holds high nutritional values to the benefit of mankind. Activities of salinity in arid and semi-arid region have drastically reduced the production of wheat grains. Selenium (Se) is a micronutrient required by plants in small concentration to aid their growth. This study was aimed at identifying impact of Se on salinity-stressed wheat plants. Wheat seeds were soaked for eight hours in 0, 50, 100 and 150 mg/L Selenite concentrations and five sterilize-treated seeds were sown in 5 kg quantity of soil. This was subjected to 0, 100 and 200 mM of Sodium chloride (NaCl) concentration, respectively. The study revealed that Se increased production/expression of superoxide dismutase and catalase enzymes under salinity stress, thus growth of wheat plants was improved. Although the effects of Se on the wheat plants were concentration-based, nevertheless low lipid peroxidation and plant growth at 150 mg/L of Se were observed. Toxicity of Se to wheat plant could occur when there is no salinity stress. Therefore, farmers are encouraged to prime wheat seeds with 150 mg/L Se when cultivating saline soils.
