  1. All comparisons except for the last column (C.V.) have been carried out using the mean values of images (i.e. only the 48 observation belonged to the monocultures)
  2. Bolded values show the significant differences (P < 0.001).
  3. MGW mean grain weight, WI well-irrigated, DI: deficit-irrigated
  4. *Tukey test; different letters in each row, show the significant differences among cultivars.
  5. **Coefficient of variation calculated only using the data of single grains of monocultures (including 19,595 grains)
