SRWC, stabilization relative water content (%); TRSRWC, transpiration rate at stabilization RWC (mmol m−2 s−1); ChangeT, change in transpiration rate (stable relative to initial; %); RWC4h, RWC at 4 h (%); AdSL, adaxial stomatal length (µm); AdPA/SA, adaxial pore area per stomatal area (%); AbPA/SA, abaxial pore area per stomatal area (%); Adgs, adaxial gs (mmol m−2 s−1); Abgs, abaxial gs (mmol m−2 s−1); Tgs, total gs (mmol m−2 s−1).
*Significant at the 0·05 probability level; **significant at the 0·01 probability level; ***significant at the 0·001 probability level.
†The analysis was also carried out for (1) abaxial stomatal density (mm−2); (2) adaxial stomatal density (mm−2); (3) total stomatal density (mm−2); (4) percentage of stomata on the abaxial leaf side (%); (5) abaxial stomatal length (µm); (6) abaxial stomatal width (µm); and (7) adaxial stomatal width (µm), where lack of significance (P > 0·05) was found in the ILs (see Supplementary Dataset).
