All measurements were taken 24 h into treatment. LER, leaf elongation rate; NPR, net photosynthetic rate; g_s, stomatal conductance; C_i, intercellular CO₂; T, transpiration rate; Ψ_leaf, leaf water potential; RWC, relative water content; T_leaf, leaf temperature. Values are means ±SE, n=3–4. Superscript letters indicate significant differences (LSD multiple comparison test, P <0.05).
