Other claims from this paper (12)
- Intervention effect Cadmium added to semisolid medium at 1, 5 and 50 µmol/L inhibited biomass accumulation of barley plants relative to basic nutrient medium controls.
- Intervention effect Cadmium at 1 to 50 µmol/L tended to decrease Zn and Cu concentrations in shoots and roots and Fe in shoots of barley plants.
- Intervention effect Cadmium exposure increased superoxide dismutase (SOD) and peroxidase (POD) activities in barley relative to plants not subjected to Cd, indicating a stress response.
- Intervention effect Zn at 300 µmol/L or ASA at 250 mg/L could alleviate the physiological changes caused by Cd toxicity in Cd-stressed barley to different extents.
- Intervention effect Zn at 300 µmol/L reduced MDA content in shoots by 4.8%–17.8% relative to 50 µmol/L Cd-stressed barley (p≤0.01).
- Intervention effect Zn at 300 µmol/L reduced MDA content in roots by 0.5%–19.7% relative to 50 µmol/L Cd-stressed barley (p≤0.01).
- Intervention effect ASA at 250 µmol/L reduced MDA content in shoots by 1.3%–7.4% relative to 50 µmol/L Cd-stressed barley.
- Intervention effect ASA at 250 µmol/L reduced MDA content in roots by 2.6%–4.5% relative to 50 µmol/L Cd-stressed barley.
- Intervention effect ASA addition may enhance Cd translocation from root to shoot in barley.
- Intervention effect Adding 0.1 µmol/L Cd slightly increased dry mass of barley.
- Intervention effect Adding Zn or ASA to Cd-stressed medium increased biomass accumulation of barley.
- Recommendation ASA would be unsuitable for edible crops grown in Cd-contaminated soils to alleviate Cd phytotoxicity.
