Abstarct: The development of industry and agriculture increasingly has implications for conservation is the most important effects of uncontrolled entrance of heavy mextals can be noted in the life cycle of mextals such as lead, nickel and zinc, which leave their irreparable damage. Phytoremediation is one way to bring out these elements of the environment. In this regard factorial experiment in a randomized complete block design with four replications was performed University anymore. Factors examined include the lead in the three-level (0) control, 100 and 200 (mg per kg of soil), EDTA chelates at two levels (0) control, 5 (mmol per kg of soil) and citric acid solution at two levels (0) control and 1 (g per kg of soil) that on Tuesday sorghum, pigweed and sunflower were studied. The results showed that lead treatment resulted in significant reduction in shoot fresh weight and dry weight of roots and shoots, reduced height and chlorophyll content of sorghum was in the presence of citric acid and EDTA The increase in these traits. Lead pigweed plant fresh weight decreased total chlorophyll in plants results in similar sorghum and sunflower in between citric acid reduced total dry biomass at the plant. As well as other traits in Kalat EDTA Increased the lead concentration roots, lead in soil, transfer factor and concentration factor in plant biology and weed seeds increased the lead concentration in the plant root, lead content, transfer factor and environmental factor was condensed while only an increase in sorghum transfer factor in the plant. The presence of citric acid also decreases the concentration of lead in root pigweed and increased lead content in the plant and reduce lead content in the sunflower plant and reduce plant stress tolerance in weed and sunflower. The combination of citric acid and EDTA Lead concentrations in the root pigweed and sunflower and tolerance index were observed in sorghum. With results in factors related to the phytoremediation plant and weed, sunflower, sorghum Nest to have achieved the best results.
