In order to investigate the effect of mycorrhiza fungi on the phytoremediation of lead by corn, a pot experiment as factorial based on randomized complete blocks design with 3 replications was performed in Research Farm of Islamic Azad University, Saveh branch. The first factor was use and non use of mycorrhiza (Glomus interaradices strain) and the second factor was amounts of 0, 200, 300 and 400 mg/kg of lead nitrat in soil. The results showed that mycorrhiza in inoculated plants in compared with non inoculated plants increased significantly concentration and content of lead. Increasing in amount soil lead increased concentration and content of lead in corn. Morphological characteristics including shoot height, shoot dry weight and root dry weight of inoculated plants were significantly higher than non inoculated plants in all levels of used lead. Mycorrhiza increased lead extraction from soil by corn.
