Other claims from this paper (18)
- Intervention effect γ-Fe2O3 nanoparticles at 20–100 mg/L did not significantly change chlorophyll content or root activity in Citrus maxima.
- Intervention effect Fe3+ at the same exposure range did not significantly change chlorophyll content or root activity in Citrus maxima.
- Intervention effect No oxidative stress occurred in Citrus maxima roots under any Fe treatment.
- Intervention effect In Citrus maxima shoots, 20 and 50 mg/L γ-Fe2O3 NPs did not induce oxidative stress.
- Intervention effect In Citrus maxima shoots, 100 mg/L γ-Fe2O3 NPs induced oxidative stress.
- Association Iron accumulation in Citrus maxima shoots was positively correlated with the dosages of γ-Fe2O3 NPs and Fe3+.
- Observation Accumulated iron in Citrus maxima shoots was not translocated down to roots.
- Intervention effect γ-Fe2O3 NPs down-regulated ferric-chelate reductase (FRO2) gene expression in Citrus maxima.
- Intervention effect Fe3+ down-regulated ferric-chelate reductase (FRO2) gene expression in Citrus maxima.
- Intervention effect γ-Fe2O3 NPs exposure down-regulated Nramp3 gene expression in Citrus maxima.
- Intervention effect The 100 mg/L γ-Fe2O3 NPs treatment gave higher wax content in Citrus maxima leaves.
- Intervention effect The 20–100 mg/L Fe3+ treatment gave higher wax content in Citrus maxima.
- Association The WIN1 wax-formation gene was downregulated or unchanged in Citrus maxima compared with the control.
- Association The ABCG12 wax-transport gene was downregulated or unchanged in Citrus maxima compared with the control.
- Intervention effect γ-Fe2O3 NPs foliar spray had an inconsequential effect on Citrus maxima growth.
- Intervention effect Fe3+ foliar spray had an inconsequential effect on Citrus maxima growth.
- Observation Citrus maxima plants exposed to γ-Fe2O3 NPs and Fe3+ were in iron-replete status.
- Recommendation The authors recommend NPs as a foliar fertilizer for Citrus maxima on the basis of these comparisons.
