Note. Spearman's rho correlation matrix for variables measured in drought‐stressed plants (DS) and calculated variables from both the DS and well‐watered (WW) treatments (ratio: WW‐DS/WW). Blade L DS: length of the blade in DS plants at the end of the experiment; Blade L ratio: reduction in length of the blade (WW‐DS/WW); Blade W DS: width of the blade in DS plants at the end of the experiment; Blade W ratio: reduction in width of the blade (WW‐DS/WW); LLL dim ratio: reduction in last ligulated leaf dimensions (blade width*blade length*0.725) (WW‐DS/WW); LLLdim DS: last ligulated leaf dimensions (blade width*blade length*0.725) measured in DS plants at the end of the experiment; PLA DS: plant leaf area measured in DS plants at the end of the stress treatments FTSW 0.2; Rolling DS: leaf rolling score measured in stressed plants at the end of the experiment (FTSW 0.2); SDWratio: reduction of shoot biomass (WW‐DS/WW); Sheath L DS: length of the sheath in DS plants at the end of the experiment; SLA DS: specific leaf area of Leaf Number 7 measured at the end of the experiment in DS plants; SLA ratio: reduction in specific leaf area leaf area (WW‐DS/WW); SLA ratio: reduction of specific leaf area of Leaf Number 7 (WW‐DS/WW).
