Abstract
The effect of priming winter rye (Secale cereale L., var. Pamiat’ Khudoerko) and wheat (Triticum aestivum L., var. Dosconala) seeds with nitrogen oxide (NO) donor sodium nitroprusside (SNP) on their frost resistance was studied. The NO donor at concentrations of 0.1–0.5 mM increased the cold-hardening ability of seedlings of both cereals (6 days at 2–4°С), leading to a significant increase in their survival after freezing at –6 and –8°С. Seed treatment with SNP contributed to an increase in the content of sugars, proline, anthocyanins, and UV-B absorbing flavonoids in cereal seedlings. An increase in the activity of superoxide dismutase and guaiacol peroxidase in them was also detected. After cold hardening, especially after freezing, the content of the lipid peroxidation product malondialdehyde in seedlings grown from seeds primed with SNP was lower than in the corresponding controls. It was concluded that nitrogen oxide enhanced the cold-induced activation of antioxidant and osmoprotective systems of cereals.
