Table 1.

Results of a three-way ANOVA test showing interaction between experimental factors. Statistical significance is denoted by bold font. Significance was established at p ≤ 0.05. Abbreviations are defined as Emax (maximum transpiration rate), Amax (maximum photosynthesis rate), G_Smax (maximum stomatal conductance), WUE_max (maximum water use efficiency), and ABA (abscisic acid).
