From: Exo-ethylene application mitigates waterlogging stress in soybean (Glycine max L.)
Root image and root surface area (RSA) in soybean plants during and after WL treatment. White bar signifies 5 cm2 (W: 1 cm × L: 5 cm). Vertical bar with error bar shows the average with standard error (n = 5). In the figure, red arrows indicated adventitious roots. During the same stress exposure period, different letters indicate significant difference at P < 0.05 and data were analyzed by Duncan’s multiple range test. WL = waterlogging; DAT = days after treatment; and ETP = ethephon
