Popis: International audience; Canna indica L. (CiL) was used here in phytoremediation of mining soils. Our work evaluated the effect of AMF (i) on the growth and (ii) on the uptake of heavy metals (HM). The tests were conducted in the greenhouse on mining substrates collected from the Kettara mine (Morocco). The mine soil was amended by different proportions of agricultural soil and compost and then inoculated with two isolates of AMF (IN1) and (IN2) of different origins. After six months of culture, the results show that on mining soils (100%) only AMF (IN2) was able to colonize the roots of CiL with a frequency of 40 +/- 7% and an intensity of 6.5 +/- 1.5%. Also, the lowest values of shoot and root dry biomass are obtained on these mining soils with respectively 0.30g and 0.27g. In contrast, the accumulation of HM was higher and reached more than 50% of that contained in the mining soils, the highest values with 138mg kg(-1) Cu2+, Zn2+ 270mg kg(-1) and 1.38mg kg(-1) Cd was recorded. These results indicate that the colonization of CiL roots by AMF (IN2) could significantly improve its potential to be used in phytoremediation of polluted soil.
