“…However, it is unknown whether some rootstocks are capable of regulating the transport of Na + or/and Cl -to leaves [33]. Based on our results, the capacity to regulate Na + and Cl -uptake and transport was linked to the ability of rootstocks, and not to the grafting process itself (comparing A/5 vs. A/12 and A/14), indicating that the physiological and biochemical mechanisms of these salts operate at the rootstock level, as observed in grafted melon plants [7] or cucumber plants [8].…”

“…This increased tolerance of grafted plants is generally associated with their capacity to exclude or retain and/or accumulate toxic ions, Na + and Cl -in rootstock roots, thus limiting their transport to leaves rather than through the synthesis of osmotically active metabolites or the induction of antioxidant systems [6][7][8].…”

“…Salinity can affect photosynthesis as a result of ion imbalance, ion toxicity and osmotic stress in plants 14,22 . A limitation of CO2 supply due to partial stomatal closure has been described as an early response to salt stress 21 .…”

“…Other studies have shown little or no effect on Fv/Fm 21,25-27 even when leaf growth and gas exchange were reduced. The decrease of stomatal conductance and the photosynthesis rate, leaving PSII unaffected suggested a highly resistant PSII activity under stress conditions 26,28 and/or that the limitation of photosynthesis by reduction of Rubisco activity does not occur until this stress is highly severe 14,29 . Based on fluorescence and gas exchange parameters, our results suggested that diffusional restriction is the main factor that limits photosynthesis in sensitive pepper genotypes in our salinity conditions.…”
