Effect of flood depth on seedling emergence shoot and root biomass of I. rugosum at various flood timing d after sowing.

Parameter estimates [Emax, maximum parameter (%); T50, flood time to reach 50% of maximum parameter (flood timing DAS); and Erate, slope] of a three-parameter sigmoid model {E = Emax/(1 + e [- (x - T50)/Erate]} fitted to seedling emergence data and biomass data in Fig 7, for biomass E replaces with B. Values in parentheses represent standard error of the mean.
