Other claims from this paper (9)
- Intervention effect Blueberry anthocyanin spray reduced cadmium in rice grain under both cadmium stress levels.
- Intervention effect Blueberry anthocyanin spray increased rice yield under cadmium stress.
- Intervention effect The spray increased anthocyanin and cadmium concentrations in rice leaves.
- Recommendation The authors identified 7.5 g/L anthocyanin as the best spray concentration.
- Mechanism Anthocyanin spraying fixed cadmium in soluble and organelle fractions in leaves, limiting transfer to grain.
- Intervention effect Anthocyanin spray reduced hydrogen peroxide and MDA accumulation in rice leaves.
- Intervention effect The 7.5 g/L spray relieved cadmium oxidative damage under 1.0 mg/kg cadmium stress.
- Mechanism The spray may chelate cadmium ions and immobilize cadmium in rice leaves.
- Recommendation The authors recommend blueberry anthocyanin as a foliar resistance agent to limit grain cadmium and toxicity.
