In the present work the ability of the arbuscular mycorrhizal fungus (AM), Glomus mossae to enhance heavy metal uptake and plant tolerance was tested in Cannabis sativa. Industrial hemp was germinated in soil inoculated with Glomus mossae; after two weeks the plantlets were transferred in soil contaminated with 150 ppm of Cr and 100 ppm of Ni and Cd. The plants were analysed at ripeness. Preliminary results suggested an increase of Cd and Ni concentrations in the root of plant colonized by mycorrhizal fungus in comparison with the plants grown in soil containing only heavy metals. Cr was not accumulated both in mycorrhizal-colonized and non-inoculated plants. Key words: Soil restoration, Cannabis sativa, Mycorrhiza |
