Effect of NH4/NO3 ratio on gas exchange, membrane leakage, and water relations parameters in medical cannabis plants. Net photosynthesis rate (A), transpiration rate (B), stomatal conductance (C), intercellular CO2 concentration (D), relative water content (RWC) (E), osmotic potential (F), intrinsic water use efficiency (WUEi) (G), and membrane leakage (H). Presented data are averages ± SE (n = 5). Different small letters above the means represent significant differences between treatments by Tukey HSD test at α = 0.05.
