Fig. 6

Salt-induced morphological responses of two contrasting genotypes under different NaCl treatments. a NT030 (tolerant) and NT131 (susceptible) DH genotypes were germinated at the indicated NaCl treatments; all images were scanned after 7 days. b Root hairs of two genotypes from 160, 240 and 320 mM NaCl treatment were compared at the points indicated by the red arrows. c Seedlings germinated for 7 days in 240 mM NaCl were transferred to no-salt conditions for an additional 7 days; old (yellow) and new (white) roots are indicated. d–f Root and shoot lengths under 160 mM, 240 mM and 320 mM NaCl treatment were observed for 14 days (7 days of salt-stress conditions plus 7 days of recovery without salt). Blue and red lines refer to NT030 and NT131, respectively. All values are averages of three replications. Scale bars in a, b, c = 6, 2 and 4 cm, respectively
