Other claims from this paper (6)
- Observation Foliar Cd in baby leaf spinach varied from about 2 to 100 mg/kg DW in Experiment 1, with no evidence of Cd toxicity.
- Intervention effect Temperature and CO2 manipulation caused large differences in plant growth of baby leaf spinach in Experiment 2.
- Intervention effect Foliar Cd was lower in chambers with increased temperature.
- Intervention effect Foliar Cd was higher in chambers with elevated CO2, which raises concern about dietary Cd exposure.
- Association Transpiration and foliar Cd uptake of baby leaf spinach were positively and strongly correlated, also on a dry-weight basis.
- Mechanism The data are consistent with Cd transport by mass flow towards the roots being a substantial contributor to Cd uptake by spinach.
