  1. Where three samples could be measured, values are expressed as mean ± standard error of the mean; where fewer than three samples could be measured, only the mean is given
  2. “-” Indicates that measurements were not made due to the growth stage
  3. “m.v.” Indicates missing data due to cuticle separation from cell walls
  4. aNote that at GS 85, caryopsis measurements comprise the husk and pericarp cuticles, whereas only the pericarp is measured on the caryopsis surface at earlier growth stages
