| Abstract: | Na_2SeO_3 was used as Se source was applied to the seedlings of wheat cultivar 95319. The results showed that Na_2SeO_3 at the rate of 0.75 mg/L enhanced the activity of glutathione peroxidase (GSH-Px), promoted the growth of the wheat seedlings, increased the contents of soluble sugars and proteins, helped to maintain the balance of the anti-oxidase system, decreased the content of MDA and electrolyte leakage and improved the stress resistance of the seedlings. |
