Other claims from this paper (13)
- Intervention effect Leaf total iron did not increase with iron supply.
- Association Active leaf iron increased as applied iron increased.
- Association Chlorophyll content increased with applied iron.
- Association Leaf absorptance and maximum PSII efficiency decreased slightly at the lowest active iron level.
- Association Non-photochemical quenching was greater at the lowest active iron level.
- Association PSII quantum efficiency declined as active iron declined.
- Association The xanthophyll cycle pool, lutein and beta-carotene increased as active iron declined on a chlorophyll basis.
- Association Neoxanthin increased at the lowest iron level.
- Intervention effect Superoxide dismutase, ascorbate peroxidase and monodehydroascorbate reductase activities rose under iron deficiency.
- Intervention effect Dehydroascorbate reductase and glutathione reductase activities rose under iron deficiency.
- Association Ascorbate, dehydroascorbate and reduced glutathione were greater at the lowest active iron levels.
- Observation Ascorbate redox and glutathione redox ratios did not differ.
- Mechanism The authors interpret xanthophyll thermal dissipation and the ascorbate-glutathione antioxidant system as enhanced by iron deficiency.
