    • Figure 1. 

      Soil water content in the drought-sensitive 'CG021' and the drought-tolerant 'CG101' during the experiment. Bars on the top indicate LSD values for the comparison among treatments on a given day.

    • Figure 2. 

      (a) Relative water content, (b) rate of water loss, and (c) rate of water absorption in the drought-sensitive 'CG021' and the drought-tolerant 'CG101' during the experiment. Vertical bars indicate LSD values for the comparison among treatments on a given day. Error bars indicate the standard error (SE). Asterisks indicate significant differences (* p < 0.05, ** p < 0.01, *** p < 0.001) between different genotypes at a certain time point.

    • Figure 3. 

      Leaf wax content in the drought-sensitive 'CG021' and the drought-tolerant 'CG101' during the experiment. Different letters indicate significant differences between different treatments at a certain point in time (p < 0.05).

    • Figure 4. 

      The cuticular wax composition in the drought-sensitive 'CG021' and the drought-tolerant 'CG101' after 24 d of drought stress. Different letters indicate significant differences between different treatments (p < 0.05).

    • Figure 5. 

      The carbon chain length of the cuticular wax composition in the drought-sensitive 'CG021' and the drought-tolerant 'CG101' after 24 d of drought stress. Different letters indicate significant differences between different treatments (p < 0.05).

    • Figure 6. 

      The relative expression of cuticular wax-related genes in the drought-sensitive 'CG021' and drought-tolerant 'CG101' after 24 d of drought stress. Different letters indicate significant differences between different treatments (p < 0.05).
