Abstarct: Green remediation or phytoremediatin of heavy mextals is one of the most cheapest technology and compatible with environment strategy, which is practical way to remove pollution from agricultural soil. Research has shown that some medicinal plants can be cultivated in soil contaminated with heavy mextals without evidence of these hazardous elements in end products, like essence. In order to investigate phytoremediation capability of peppermint (Mentha piperita L.), a greenhouse study was conducted at the research greenhouse of the Agricultural Faculty of Ferdowsi University of Mashhad (Mashhad, Iran) between January and April 2013 to assess the effects of biochar and mycorrhizal fungi on accumulation characteristics of cadmium (Cd) in peppermint (Mentha piperita L.) grown in contaminated soil. A factorial experiment laid out in Randomized Complete Block Design (RCBD) with three replications was used. Results showed that application of biochar and inoculation of AMF increased dried weight of shoots and roots. Also application of biochar caused increase on essence percentage in all AMF inoculated peppermints. It seems that AMF inoculation especially with Glomus intraradices and bichar application have a significant roll in development of phytoremediation. Comparison of interaction effects of biochar and Cd showed that application of biochar with Cd at 100 mg/Kg level, had the highest Cd accumulation in root. AMF and biochar had positive impact on growth and Cd uptake in root and shoots of peppermint.
