Other claims from this paper (10)
- Intervention effect Sweet orange seedling leaves maintained turgor above controls.
- Intervention effect Rangpur lime and Cleopatra mandarin seedlings tended to lose turgor under 150 mM NaCl.
- Observation Rangpur lime and Cleopatra mandarin rootstocks restricted chloride uptake or transport to shoots.
- Intervention effect Mature leaves on all rootstocks accumulated high sodium concentrations during salt treatment.
- Intervention effect Leaf potassium concentration remained similar to controls.
- Mechanism Sodium and chloride largely explained reduced osmotic potential on four rootstocks.
- Mechanism Chloride accounted for about half of osmotic-potential reduction on Rangpur lime and Cleopatra mandarin.
- Intervention effect Salt increased stomatal resistance on all rootstocks.
- Observation Stomatal resistance recovered only partly after salt ceased.
- Mechanism Incomplete recovery may relate to retained leaf sodium.
