Genotypic differences in the responses of physiological traits to drought stress. The genotypes H99, MS71, NC358, OH43, TX303, TZi8 and W153R and four physiological traits, i.e. stomatal conductance (gs, mol H2O m−2 s−1), effective quantum yield of photosystem II (φPS2), transpiration rate (E, mmol H2O m−2 s−1) and leaf water potential (ψ, MPa), were selected for this analysis. Physiological traits of well-watered (WW) and water-deficit (WD) maize plants were monitored from V4 (four fully developed leaves) until the silking stage. The average trends of the WW and WD treatments are indicated by blue solid and red dashed lines, respectively. The gray shading around the lines represents the 95% confidence interval of the average. Individual measurements of the plants are visualized by blue dots (WW) and red circles (WD). The black vertical line indicates the start of the WD treatment. The days on which significant treatment differences were observed are marked with a light gray vertical shading behind the average trends and dots (P < 0.05)
