Abstract

Heavy metal pollution is one of the most significant ecological problems in the whole world. According to the environmental protection agency (EPA), Pb is the most important heavy metal contaminant in the environment. In this study the effects of Pb stress (0, 120, 240, 500, 1000 mM Pb) on 7-day seedlings of MEDICAGO SATIVA L. were investigated in a hydroponic culture. The results indicated Pb accumulation in roots and aerial parts increased and an increasing trend in total biomass was observed with increase of Pb concentration in medium which reduced later due to increasing Pb accumulation. Compared with control seedlings, increase in the production of MDA and H2O2 which are the indices of oxidative stress, were observed in the seedlings under Pb stress. Moreover, increase in total FLAVONOIDS production, and PEROXIDASE activity in roots and shoots of the treated seedlings were observed under Pb stress. Content of total phenolics decreased in roots and increased in shoots comparing with the control.
