^aDays of drought stress were counted since May 31st, 2016 (D0) when all maize plants were not watered anymore
^bThe growing stage was determined by the standard provided by Bondesio et al. [9]. V6 represents the stage that plants have 5 leaves, growth point is 20–25 mm below the ground, and cob and tassel is at initiation stage; V10–V11 represents the stage of cob development with around 10–11 leaves; VT represents the beginning of pollination stage; R1 represents the end of pollination stage; R2–R3 represents the stage of kernel development; R6 represents the end of mass grain stage and plants are ready for being harvested
