- Intervention effect Foliage of Valencia scions grafted to Trifoliata had higher chloride than foliage of scions on Cleopatra mandarin.
- Intervention effect Foliage of Valencia scions grafted to Trifoliata had lower sodium than foliage of scions on Cleopatra mandarin.
- Intervention effect Salt accumulation in leaves on both rootstocks contributed to more negative osmotic pressures.
- Intervention effect Turgor was maintained at or above the level in control leaves despite salinisation, through salt accumulation in leaves.
- Intervention effect CO2 assimilation rate was reduced by salinity.
- Association Salinity inhibited CO2 assimilation more in leaves on Cleopatra mandarin than in those on Trifoliata.
- Observation Reductions in CO2 assimilation and stomatal conductance were usually in step with each other.
- Observation Intercellular partial pressure of CO2 changed little despite large changes in gas exchange.
- Observation The impact of salt on CO2 assimilation was expressed to a greater degree at high intercellular CO2 partial pressure.
- Intervention effect The extent of the photosynthetic response to salt at high intercellular CO2 partial pressure was independent of light level during growth.
- Observation Room temperature chlorophyll a fluorescence induction kinetics remained unaltered.
- Intervention effect Scions grafted to Trifoliata showed a slower onset of photosynthetic dysfunction after salinisation than scions on Cleopatra mandarin.
- Observation Photosynthetic sensitivity to increased leaf chloride appeared to diminish on Trifoliata.
- Mechanism The authors attribute the rootstock effect on scion performance to a superior capacity of Trifoliata to exclude sodium ions from Valencia scions.
