| الوصف: | The present study investigates the interactive mechanism involved during the uptake of heavy metals and stress tolerance in Brassica juncea L. seedlings under the influence of Mn(II) in binary combinations with Cr(VI), Ni(II), Co(II) and Cu(II) in terms of changes in antioxidative enzymes-superoxide dismutase (SOD), guaiacol peroxidase (GPX), catalase (CAT), ascorbate peroxidase (APX) and glutathione reductase (GR). The order of uptake of heavy metals by the seedlings in single metal solutions was observed to be, Mn>Cu>Co>Cr>Ni. As revealed by multiple regression and path analysis, manganese (Mn) in binary combination with other heavy metals mutually decreased the uptake of each other. Mn and other metals were antagonistic to each other for the activities of SOD, GPX, APX and GR, and decreased the effect of each other through interaction, whereas antagonism between these metals increased the activity of CAT. |
