Other claims from this paper (10)
- Intervention effect Cd stress significantly inhibited tobacco growth.
- Intervention effect Cd stress increased Cd accumulation in tobacco.
- Intervention effect Cd stress induced oxidative damage in tobacco.
- Intervention effect Si treatment reduced Cd concentration in different tobacco organs.
- Intervention effect Si treatment decreased the Cd translocation factor and bioconcentration factor in tobacco.
- Intervention effect Si treatment significantly enhanced the activities of SOD, POD and CAT in tobacco roots and leaves.
- Intervention effect Si treatment elevated the activities of APX and GR in tobacco.
- Intervention effect Si treatment increased the accumulation of AsA and GSH in tobacco.
- Intervention effect Si treatment decreased MDA concentration in tobacco.
- Mechanism The authors conclude that Si mitigates Cd stress in tobacco by limiting Cd accumulation and transport and by coordinately activating enzymatic and non-enzymatic antioxidant systems.
