Other claims from this paper (10)

Intervention effect Cd stress increased Cd accumulation in tobacco.
Intervention effect Cd stress induced oxidative damage in tobacco.
Intervention effect Si treatment increased tobacco biomass under Cd stress.
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.
