图 3 水杨酸处理对盐胁迫下甘草幼苗叶片中MDA含量的影响 CK0: 无SA处理+无盐胁迫; SA0: SA处理+无盐胁迫; CK100: 无SA处理+100 mmol L-1 NaCl溶液胁迫; SA100: SA处理+100 mmol L-1 NaCl溶液胁迫; CK200: 无SA处理+200 mmol L-1 NaCl溶液胁迫; SA200: SA处理+200 mmol L-1 NaCl溶液胁迫。MDA: 丙二醛。柱上不同小写字母表示在0.05水平上有显著性差异。

Fig. 3 Effect of salicylic acid on the MDA contents in G. uralensis seedling leaves under salt stress CK0: no SA treatment + no salt stress; SA0: SA treatment + no salt stress; CK100: no SA treatment +100 mmol L-1 NaCl stress; SA100: SA treatment +100 mmol L-1 NaCl stress; CK200: no SA treatment +200 mmol L-1 NaCl stress; SA200: SA treatment +200 mmol L-1 NaCl stress. MDA: malondialdehyde. Different letters above the bar mean significant difference at the 0.05 probability level.
