  1. aDays of drought stress were counted since May 31st, 2016 (D0) when all maize plants were not watered anymore
  2. 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
