Implication

Controlled greenhouse study demonstrates cultivar-dependent osmotic adjustments to salinity in olive plants, indicating that salt tolerance depends primarily on ion exclusion capacity.

Key Points

To determine whether genotypic differences in salinity tolerance between two olive cultivars are associated with leaf water relations and osmotic adjustment parameters.
Grew 1-year-old rooted cuttings of olive cultivars Frantoio and Leccino either hydroponically or in soil within a greenhouse.
Exposed plants to 0, 100, or 200 mM NaCl treatments for 35 days, followed by a 30-to-34-day relief period to monitor stress recovery.
Salinity reduced osmotic potential at full turgor from -2.50 to -3.16 MPa in Frantoio and from -2.23 to -3.37 MPa in Leccino across 0 to 200 mM NaCl treatments.
Net solute accumulation was higher in the salt-sensitive cultivar Leccino, with Na+ contributing 15.6% to 20.0% of total osmotic potential at full turgor under 200 mM NaCl compared to 0.1% to 2.1% in controls.
Leaf water potential and relative water content fully recovered after stress relief, whereas osmotic potential recovered completely in the 100 mM treatment but remained altered at 200 mM.
