Other claims from this paper (13)
- Intervention effect Foliage of scions grafted to Trifoliata had higher chloride levels than foliage of scions grafted to Cleopatra mandarin.
- Intervention effect Foliage of scions grafted to Trifoliata had lower sodium levels than foliage of scions grafted to Cleopatra mandarin.
- Intervention effect Leaf water potential declined with salinisation.
- Mechanism Salt accumulation in leaves contributed to more negative osmotic pressures and maintenance of turgor at or above control-leaf levels.
- Intervention effect CO2 assimilation rate was reduced by salinity.
- Association Inhibition of CO2 assimilation was greater in leaves on Cleopatra mandarin than in leaves on Trifoliata.
- Association Reductions in CO2 assimilation and stomatal conductance were usually in step with each other.
- Observation Intercellular CO2 partial pressure showed little change despite large changes in gas exchange.
- Association Salinity expressed a greater impact on CO2 assimilation at high intercellular CO2 partial pressure.
- Association The extent of photosynthetic response to salt at high pI was independent of light level during growth.
- Observation Room temperature chlorophyll a fluorescence induction kinetics remained unaltered.
- Association Photosynthetic sensitivity to increased leaf chloride appeared to diminish on Trifoliata.
- Mechanism The rootstock effect on scion performance was attributed to a superior capacity of Trifoliata to exclude sodium ions.
