From: Exposure to lower red to far-red light ratios improve tomato tolerance to salt stress
Effects of different R: FR values on proline, soluble protein, and MDA content, and relative electrolyte leakage in tomato seedlings under salinity stress. a proline content. b soluble protein content. c MDA content. Proline, soluble protein and MDA contents were measured 0, 2, 4, 6, and 8 days after exposure to the salinity treatment. d relative electrolyte leakage, measured 8 days after 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), Bars with different letters are significantly different at the 0.05 level (Duncan’s multiple range test)
