“…As expected, application of Cd to the soil led to a higher concentration of the metal in the shoots of maize, which is in agreement with other studies (Mohan andHosetti 1997, Hegedüs et al 2001). Supplementation of Cd contaminated soils with S showed an influence of the concentrations of Cd in plants (Tichý et al 1997, Kayser et al 2000, Cui et al 2004).…”

“…Toxic level of Cd can result from environmental pollution due to mining, smelting and dumping of municipal sewage wastes, manufacturing processes and disposal of used batteries. High concentration of Cd in the soil may inhibit seed germination and exert a wide range of adverse effects on the growth and metabolism of plants (Mohan andHosetti 1997, Hegedüs et al 2001). …”

“…Effects of Cd stress on plant growth and development were reported in several studies (Mohan and Hosetti 1997, Hegedüs et al 2001, Prasad et al 2001, Shah et al 2001. However, investigations on the combined effects of elemental S with Cd on antioxidative processes are rare.…”

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.

“…At day 9, the inhibition by copper treatment was approximately 60 %, compared to control. This finding corroborates numerous reports that heavy metals cause a decrease in protease activity; Cd (Bishnoi et al 1993;Shah and Dubey 1997;Kuriakose and Prasad 2008), Pb (Mohan and Hosetti 1997) and Ni (Maheshwari and Dubey 2007). The inhibition could not be explained only by the direct effect of the metal ion on the enzymatic proteins, since ACA was reduced less than 20 % after Cu incubation in vitro with the control enzymatic extract (9 days of H 2 Ogermination; Fig.…”

The changes in the protease activities of bean cotyledons were investigated in response to copper stress. Assays using synthetic substrates and specific protease inhibitors followed by activity measurements and electrophoresis analysis allowed to study the classes of enzymes involved in the storage protein mobilization during the germination of bean (Phaseolus vulgaris L) seeds, and then identify which ones were affected in the presence of 200 μM CuCl 2 in the imbibition medium. Copper treatment affected embryo growth and total protease activity. The results of SDS-gelatin-PAGE show that Cu excess led to a decrease in protease activity of 45 to 66 kDa. Moreover, cysteine-, aspartic-and metallo-protease activities were markedly lowered under copper stress, while serine-protease one was enhanced as well as its activity dependent abundance in comparison with control. However, the relative distribution of major cysteine protease in H 2 O-germinated seeds was significantly diminished after Cu exposure. Thus, copper excess can disturb the nitrogen freeing from reserve tissues at enzymatic level; differential responses of protease classes are discussed, notably, cysteine protease in the way of storage protein mobilization and serine protease in protective mechanism one.

“…Kastori et al [4] found that the treatment of sunflower plants with lead diminished the concentrations of chlorophylls and carotenes, while Larsson et al [5] observed a reduction in the chlorophyll concentrations of plants exposed to cadmium. Mohan and Hosetti [6] suggested that both cadmium and lead drastically depressed catalase activity but stimulated peroxidase activity. They reported that the interaction between lead and cadmium on growth of other plants e.g., the root of Juncus acustus, was strongly inhibited by lead nitrate.…”
