Other claims from this paper (16)
- Intervention effect Excess zinc produced chlorotic cucumber leaves and reduced shoot growth by 20%.
- Intervention effect Excess zinc reduced cucumber root growth by 49%.
- Observation Zinc treatment caused chlorotic cucumber leaves and nutrient imbalance.
- Observation Zinc treatment caused nutrient imbalance in cucumber.
- Intervention effect Fullerene derivatives suppressed zinc-induced loss of cucumber leaf dry biomass by 15%.
- Intervention effect Fullerenol suppressed zinc-induced loss of cucumber root dry biomass by 40%.
- Intervention effect Fullerene derivatives did not alter cucumber shoot dry biomass.
- Intervention effect Fullerene derivatives did not alter cucumber elemental composition, including leaf zinc.
- Intervention effect Fullerenes left zinc in cucumber root xylem sap unchanged.
- Observation Zinc adsorption by tested C60 was below detection limits.
- Intervention effect C60 derivatives slightly changed metabolite profiles in zinc-stressed cucumber.
- Intervention effect Some zinc-responsive metabolites tended to change oppositely under fullerene treatment versus excess zinc alone.
- Observation Several metabolites associated with oxidative stress protection were upregulated.
- Mechanism The authors speculate that fullerene derivatives increase antioxidant non-enzyme activity and improve some growth parameters.
- Intervention effect Fullerenes did not reduce zinc movement from cucumber roots to shoots.
- Mechanism The authors concluded that low zinc buffering in the root zone may limit fullerene efficacy against zinc toxicity.
