Influence of various concentrations of ethephon treatment on plant height (a) and chlorophyll content (b). Soybean plants were exposed to WL for 10 days. Data were collected in 5-day intervals from three replicate samples and are shown as the average ± standard error (n = 10). In the figures, different letters indicate significant difference at P < 0.05 and data were analyzed by Duncan’s multiple range test (DMRT). WL = waterlogging; DAT = days after treatment; and ETP = ethephon
