Other claims from this paper (11)
- Intervention effect Increasing soil Cd through irrigation reduced lettuce yield.
- Intervention effect Lower Cd doses increased lettuce yield in some cases.
- Observation Cadmium exposure produced no visible injury apart from reduced height and yield.
- Observation Shoot dry weight was the most sensitive parameter to cadmium, especially under water stress.
- Intervention effect Water stress suppressed nutrient element concentrations in lettuce shoots.
- Association Shoot Cd concentration and uptake declined with increasing irrigation frequency.
- Association Shoot Cd concentration and uptake increased with irrigation water Cd levels.
- Observation Shoot Cd values exceeded the recommended guideline in all conditions.
- Association Shoot Cd content was positively correlated with accumulated soil Cd.
- Method / resource The shoot Cd–soil Cd relation fit a plateau model under dry irrigation and linear models otherwise.
- Method / resource A simple linear regression predicted shoot Cd concentration regardless of plant water fluxes.
