“…There have been numerous reports on increasing malondialdehyde content induced by cadmium stress (Shah et al 2001). However, unlike our study, the content of malondialdehyde did not changed in maize root under Cd stress (Astolfi et al 2005).…”

“…A decrease was observed in catalase activity under Cd stress in the present study. Similar declines in catalase activity were reported under under Cd stress in rice, cabbage, bean, carrot, radish and pea (Chaoui et al 1997, Sandalio et al 2001, Shah et al 2001, Pandey and Sharma 2002. However, unlike our study, increased catalase activity was also observed in sunflower cotyledons and barley (Patra andPanda 1998, Gallego et al 1999) under Cd stress.…”

“…Plants exposed to Cd stress invariably show marked alterations in electron transport in both chloroplasts and mitochondria (Prasad et al 2001, Shah et al 2001, Zhang et al 2005. This results in the production of active oxygen species (AOS) such as superoxide radicals (O 2 -), single oxygen ( 1 O 2 ), hydroxyl radical (OH) and peroxide (H 2 O 2 ), which affect various cellular processes mostly concerned with the functioning of membrane systems.…”

Plants have evolved protective mechanisms to eliminate or ameliorate these damages, such as altering of antioxidant enzyme activities and antioxidant levels and enhancement of lipid peroxidation (Prasad et al 2001, Shah et al 2001.…”

The physiological response to application of elemental sulphur (S) and cadmium (Cd) of maize (Zea mays L.) grown for 60 days in pot soil was studied. The S was added into the soil with 2 rates (0 and 50 mmol/kg) and Cd was added in solution in 4 rates (0, 20, 50, 100 mg/kg). All the S and Cd were added before planting. Shoot biomass decreased with the application of Cd to the soil whether S was applied or not. The application of S and Cd to soil led to an increasing accumulation of Cd in the shoots of maize. The concentration of chlorophyll was reduced significantly in Cd-treated plants with or without supplementary S. The content of malondialdehyde (MDA) was increased significantly in treatments with S and Cd, compared to the control. The activity of peroxidases (POD) was increased but catalase (CAT) was decreased in plants treated with Cd, again with or without S, in comparison with control. POD and CAT activities decreased in all the Cd treated plants with S, as compared to the plants without S. The results suggest that Cd reduces the crop growth, concentration of chlorophyll and activity of CAT, but increases the content of MDA and activity of POD. S supplies decrease the content of MDA, activities of POD and CAT, as compared to zero S supplies at the same rate of Cd application.
