Abstract

Some plants have the ability in absorbing adequate amounts of some toxic and heavy metals. Although heavy metals contribute in the occurrence of OXIDATIVE STRESS in plant species, the plants possess various defensive mechanisms against the toxicity of such elements. One of these mechanisms is the activation of antioxidant enzymes in order to protect against oxidative injuries resulting from heavy metals. The aim of the present study was to understand the enzymatic changes of Catalase and Glutathione peroxidase in Grass pea (Lathyrus sativus) under lead and copper toxicity. In addition, the measurement of the ability in accumulating lead and copper and the effects of these elements on PROTEIN and the plant CELL NUCLEUS was another purpose of the present study. The experiment was carried out in factorial form as randomized complete design in agricultural and natural resources faculty, Karaj, in 2009. Four levels of lead (Pb (NO)3)2 (0, 200, 400 and 800 mg/kg) and four levels of copper (Cu (SO4) 2) (0, 150, 300, 450 mg/kg) were used. The results suggested the significant increase in lead and copper accumulation under different levels of the same elements (p<0.01), besides the measurement of Dityrosine and 8-hydroxy-2-deoxyguanosine contents, which increase during the peroxidation of PROTEIN and the plant CELL NUCLEUS respectively, was significant (p<0.01).The maximum toxic effects of the elements were observed at concentrations 800 and 450 mg lead and copper. The significant increase in both enzymes Catalase and Glutathione peroxidase was in response to the toxicity of the elements along with the increase in the different levels of lead and copper (p<0.01) so the remarkable increase in the activity of the two mentioned enzymes was observed at the maximum concentrations of soil lead (800 mg/kg) and copper (450 mg/kg).
