OJIP parameters and photosynthetic efficiency (Fv/Fm) in soybean plants at 15 days after WL. We measured OJIP data after 20 min of dark acclimation. Data were detected by three times and are presented as the average ± standard error (n = 10). WL = waterlogging; DAT = days after treatment; and ETP = ethephon
