Changes over time in gas exchange parameters for control and drought stressed maize plants. a A, net CO2 assimilation rate; b gs, stomatal conductance to water vapor; c Ci, intercellular CO2 concentration; d E, transpiration rate. The values of the parameters every 2 days represent the average of 20 replicates considering all studied maize genotypes. Both groups of plants (control and drought) were with soil water content at field capacity at the start of measurement (±60 days after sowing; 1st day). From there, the watering was withheld in the drought stressed plants until the substrate reached the theoretical wilting point (−1.5 MPa) on the 7th day. Bars represent standard error of the mean
