摘要
The changes of chlorophyll and malondialde-hyde (MDA) contents, plasma membrane permeability confirmed that 0.1 and 1 mmol/L sodium nitroprusside (SNP), a donor of nitric oxide (NO) in vivo, could markedly alleviate the oxidative damage to wheat (Triticum aestivum L.) leaves induced by 150 and 300 mmol/L NaCl treatments, respectively. Further results proved that NO significantly enhanced the activities of superoxide dismutase (SOD) and catalase (CAT), both of which separately contributed to the delay of O2- and H2O2 accumulation in wheat leaves under saltstress. Meanwhile, the accumulation of proline was apparently accelerated. Therefore, these results suggested that NO could strongly protect wheat leaves from oxidative damage caused by salt stress.
