Other claims from this paper (16)
- Intervention effect A dose-dependent significant reduction of plant growth occurred under increasing NaCl doses.
- Intervention effect Foliar Na and Cl concentrations increased with the highest NaCl dose, up to 6-fold.
- Intervention effect Leaf K concentration increased by about 14 % under increasing NaCl doses.
- Intervention effect Leaf N concentration increased by about 5 % under increasing NaCl doses.
- Intervention effect Leaf P concentration decreased by about 23 % under increasing NaCl doses.
- Intervention effect Stomatal conductance decreased by 20 % at the lowest NaCl dose.
- Intervention effect Transpiration rate decreased by 32 % at the lowest NaCl dose.
- Intervention effect Photosynthesis decreased by 25 % at the lowest NaCl dose.
- Intervention effect Stomatal conductance, transpiration rate and photosynthesis all decreased by about 40 % at the highest NaCl dose.
- Observation Membrane injury was rather low (11 %) even at the highest NaCl dose.
- Intervention effect Intercellular CO2 concentration was significantly reduced at the lower NaCl doses.
- Intervention effect Intercellular CO2 concentration showed no change at the highest NaCl dose.
- Mechanism At the highest NaCl dose, non-stomatal limitation of photosynthesis may occur.
- Observation Chrysanthemum Palisade White may be considered moderately sensitive to salt stress in terms of growth inhibition.
- Observation Chrysanthemum copes with long-term salt stress without visible signs of damage.
- Mechanism Maintenance of K homeostasis and proline accumulation probably alleviate the toxic effect of chloride.
