Comparison of seed germination rates between S. linearistipularis (Sl) and S. matsudana (Sm) under normal and salt stress conditions. (a) Seeds of Sl and Sm were germinated on filter paper containing aseptic water (control) or NaCl solution (100, 150, and 200 mM) for 4 days, and their germination rate (8 days) (b), germination energy (3 days) (c), and germination index (8 days) (d) were calculated. The asterisk indicates significant difference (**p < 0.01; Student’s t test). The error bar indicates SE (n = 6).
