Seed Priming Improves Biochemical and Physiological Performance of Wheat Seedlings under Low-Temperature Conditions

Wheat is a widely cultivated cereal throughout the world and stress caused by low temperatures significantly affects all stages of wheat development. Seed priming an effective method to produce stress-resistant plants. This work was carried out determine whether different methods (hormo-, halo-, osmo-, hydropriming) can increase resistance low-temperature conditions (10 °C). The effect on growth, as well biochemical physiological performance seedlings were monitored. In general, had significant stimulatory monitored characteristics. Hormo- halopriming positive vigor index, total soluble protein content seedlings. Additionally, hormopriming reduced malondialdehyde (MDA) in compared unprimed seeds. A dominant antioxidant enzymes (superoxide-dismutase, catalase, ascorbate peroxidase, guaiacol pyrogallol peroxidase) recorded after seed with KNO3. effectiveness also confirmed through increased phenolic compounds (including flavonoids), activity. HPLC analysis showed chlorogenic acid, catechin, 4-hydroxy benzoic sinapic rutin, naringin, quercetin primed grown under best effects achieved hormo- hydropriming. It concluded that be regarded promising approach for increasing stress.
