Morphological changes of salt-tolerant (ST) and salt-sensitive (SS) genotypes under salinity stress.a通用电气rmination of ST and SS under control and 300 mM NaCl conditions.bPhenotypic changes of ST and SS when 28-day-old seedlings were exposed to 300 mM NaCl for 14 d.cChanges in seed germination rate, plant survival rate, plant height, root length, root fresh weight and root dry weight of ST and SS under control and NaCl treatments.dComparative analysis of SOD activity, soluble sugar content and proline content between different groups and treatments. Scale bars = 2 cm. Multiple comparisons were performed with significant difference (*P < 0.05, **P < 0.01, one-way ANOVA and Tukey’s test; Error bars represent SD)
