From: Exposure to lower red to far-red light ratios improve tomato tolerance to salt stress
Effects of different R: FR values on on ROS (O2•− and H2O2) and ROS scavenging enzymes (SOD, POD and CAT) activities in tomato seedlings under salinity stress. a O2•− content. b H2O2 content. c SOD activity. d POD activity. e CAT activity.These parameters were measured 0, 2, 4, 6, 8 days after exposure to salinity treatment. T1, 0 mM NaCl + 7.4 R: FR; T2, 0 mM NaCl + 1.2 R: FR; T3, 0 mM NaCl + 0.8 R: FR; T4, 100 mM NaCl + 7.4 R: FR; T5, 100 mM NaCl + 1.2 R: FR; T6, 100 mM NaCl + 0.8 R: FR.Vertical bars on the lines represent the SE (n = 5)
