Alleviation of Oxidative Damage Induced by CaCl₂ Priming Is Related to Osmotic and Ion Stress Reduction Rather Than Enhanced Antioxidant Capacity During Germination Under Salt Stress in Sorghum.

ABSTRACT: Seed germination is the sensitive period to salt stress. Calcium chloride (CaCl₂) has been proved as an effective priming agent which can promote the sorghum germination under salt stress. However, there are few reports on CaCl₂ priming to improve the salt tolerance during seed germination. The present study investigated the effects of CaCl₂ priming on sorghum germination, antioxidant metabolism, osmotic regulation and ion balance under salt stress (150 mM NaCl). The results revealed that the salt stress inhibited the elongation of mesocotyl and root and reduced the germination rate of sorghum. While CaCl₂ priming significantly promoted the elongation of mesocotyl and root, and increased the germination rate of sorghum under salt stress. CaCl
