Phenotype and ROS accumulation of rice leaves after salt stress. A. Phenotype of the three rice varieties after 100 mM NaCl treated for 1 day. B. Phenotype of the three rice varieties after 100 mM NaCl treated for 5 days. C. ROS staining on leaves without NaCl treatment. Lower panels, ROS staining on leaves from seedlings treated with 100 mM NaCl for 5 days. Sample IDs were indicated. D. H₂O₂ contents in the second leaf of each rice varieties. Salt treatment durations were 0 h, 6 h and 5d, respectively
