Changes in photoinhibition in the leaves of tomato seedlings pretreated with melatonin (MT) following exposure to light during chilling. (A) The maximum quantum yield (Fv/Fm) of PSII; (B) Photoinhibition of PSII. Leaves of tomato (Solanum lycopersicum L. cv. Micro-Tom) seedlings at the three-leaf stage were pretreated with 100 μmol melatonin (MT) one time a day for 3 days. At the end of light cycle at 18:00 on day 3, seedlings were exposed to chilling (4°C) for 10 h in the dark, then in the light (400 μmol m^-2 s^-1) next morning for another 6 h. Data were collected at 0, 1, 2, 3, 4, 5, and 6 h following light exposure. The values presented are mean ± SD (n = 6).
