Mycorrhizal colonization of Gv to the roots of S. nigrum was observed in all inoculated treatments (Fig. 1), and no hyphae or
vesicle was found in uninoculated treatments. The rates of mycorrhizal colonization in all inoculated treatments were
generally high (from 71% to 82%). Compared with the Cd-unamended soil, colonization rates in 25 and 50mgCd kg1 soils
were significantly (p
