Abstract
To investigate the mechanism of exogenous Ca2+ and NO alleviting salt stress in wheat seedlings (Triticum aestivum L.),this paper treated wheat seedlings Yumai 49 with CaCl2 or SNP in response to salt stress. The results showed that 10 mmol·L-1 CaCl2 had a better effect on droping the membrane permeability,promoting the chlorophyll accumulation,raising proline accumulation and the MDA degradation of root or leaves to alleviate salt injury. Meanwhile,50 μmol·L-1 SNP had similar effect with CaCl2 on droping the membrane permeability,promoting the chlorophyll accumulation,raising proline accumulation and the MDA degradation of root or leaves. SNP+CaCl2 significantly increased proline accumulation at root of wheat seedlings and enhance POD activity. However,SNP+1 mmol·L-1 EGTA inhibited the effects of NO on alleviating salt injury. These results suggest that exogenous NO enhance wheat salt resistance and alleviate salt injury possible by enhancing Ca2+ influx by activating root Ca2+ channels and improving concentration of Ca2+ of wheat seedlings.
