Morphological changes of salt tolerant (ST) and salt sensitive (SS) in response to salinity stress. a Germination of ST and SS under control and 150 mM NaCl treatments. b Seed germination rate, plant survival rate, shoot length, shoot fresh weight, shoot dry weight and relative electrolyte leakage of ST and SS under control and salt conditions. c Growth of ST and SS was monitored when 6-days-old seedlings were subjected to 100 mM NaCl for 21d. Bars with asterisk (*) are significantly different (∗P < 0.05, ∗∗P < 0.01, two-tailed Student’s t tests) between the two genotypes
