e0“of maize (Zea mays L.) were studied to compare their response to various levels of potassium (K+) (0.1, 1, and 6 mol/m3) and sodium chloride (NaCl) (0 and 50 mol/m3) in nutrient solutions”
e5“Increasing the K+ supply in the rooting media did not improve growth reduction imposed by the 50 mol/m3 NaCl treatment”

Other claims from this paper (9)
- Association Spirit produced about 1.5 times more biomass than Jubileo at 6 mol/m3 K+ in the control.
- Association Growth of both cultivars was similar at 0.1 mol/m3 K+.
- Intervention effect Plant fresh weight of Spirit was reduced by 20% with 50 mol/m3 NaCl and 6 mol/m3 K+.
- Intervention effect Plant fresh weight of Jubileo was reduced by 30% with 50 mol/m3 NaCl and 6 mol/m3 K+.
- Association Growth reduction by salinity was associated with excessive accumulation of sodium (Na+) rather than an effect on water relations.
- Association Jubileo had a lower turgor potential than Spirit.
- Mechanism Higher salt tolerance of Spirit may be related to its greater capacity to exclude Na+.
- Mechanism High leaf Na+ may help maintain turgor but cannot substitute for K+ for adequate growth.
- Mechanism Inorganic ions accumulated in leaf tissue were sufficient for osmotic adjustment in both cultivars, with no single organic solute important.
