Comparison of root Na+ and K+ efflux rate between S. linearistipularis (Sl) and S. matsudana (Sm) seedling under normal and salt stress conditions. (a) Morphology and site of root monitored by NMT. Mean Na+ (b) and K+ (c) efflux rate from the roots of Sl and Sm seedlings (7-day-olds) after 12 h of incubation in aseptic water (control) or NaCl solutions (50 and 100 mM). The asterisk represents a significant difference (*p < 0.05; Student’s t test). The error bar indicates SE (n = 6).
