This pot experiment was carried out in a greenhouse with 4 treatments arranged in a randomized complete block. Soil of the Dong Mai village, Chi Dao commune, Van Lam district, Hung Yen province, Vietnam was analyzed and its Pb contamination was 37 times higher than the permissible standard (QCVN 03: 2008 / BTNMT). After 40 days of experimentation, mycoroot treated ferns had increased biomass and Pb content of plant parts. The increase of plant biomass depended on the dose of the inoculant applied to the soil. The Pb content accumulated up to mg/kg in the roots and mg/kg in the stalk-leaves when the ferns were treated with 40g mycoroot bio-product/plant. Ferns had lower a Pb content in each fresh biomass unit and a higher biomass weight when mycoroot bio-product was applied at a rate of 80 g/plant compared to 40 g/plant. Thus, the total amount of Pb removed from the soil was higher after the ferns were treated with 80 g/plant mycoroot bio-product ( mg Pb/pot). The total amount of Pb accumulated in the roots was always higher than in the stalk- leaves. The flexibility of Pb could be increased when soil was mixed with mycoroot bio-product before ferns were transplanted. Keywords: Fern, mycoroot mycorrhizal fungi bio-product, Pb pollution. Ảnh
