  1. The normalized value was calculated as the quotient of the trait value in a group minus the mean value of all groups divided by the mean value. The number after the underscore indicates the order of image acquisition.
  2. RL Total root length, RA Total root area, RTD Root tissue density, TRL Tap root length, MRG_TRL Mean growth rate of tap root length, MRG_RL Mean growth rate of total root length; The number after the underscore indicates the order of image acquisition.
