S—Electrical conductivity of irrigation water (ECw), S1 (0.8 dS m⁻¹); S2 (3.8 dS m⁻¹); M—Application methods, M1 (Soaking); M2 (Spraying); M3 (Spraying + Soaking); C—Ascorbic acid concentration, C1 (0 mM); C2 (0.8 mM); C3 (1.6 mM); Chl a (Chlorophyll a—μg mL⁻¹); Chl b (Chlorophyll b—μg mL⁻¹); Chl t (Total chlorophyll—μg mL⁻¹); Car (Carotenoids—μg mL⁻¹); RWC (relative water content—%); % EL (percentage of electrolyte leakage); Ci (internal CO₂ concentration—μmol CO₂ m⁻² s⁻¹); A (CO₂ assimilation rate—μmol CO₂ m⁻² s⁻¹); E (perspiration—mmol H₂O m⁻² s⁻¹); gs (stomatal conductance—mol H2O m⁻² s⁻¹); CEi (instantaneous carboxylation efficiency—[(μmol CO₂ m⁻² s⁻¹) (μmol CO₂ m⁻² s⁻¹)⁻¹]. FPD (Fruit polar diameter—mm); FED (Fruit equatorial diameter—mm); AFW (Average fruit weight—g per fruit); NFP (Number of fruits per plant); TPP (Total production per plant—g per plant).
