Effect of different arbuscular mycorrhizal fungi on Cadmium absorption of Sedum aizoon L

Abstract

Abstract In order to investigate the effect of different arbuscular mycorrhizal (AM) fungi on Cadmium (Cd) uptake of Sedum aizoon L.. Under Cd stress, five AM fungi (GMA, GM, GV, BEG167, BEG168) were inoculated to Sedum aizoon L. at 10 mg⋅kg−1 Cd concentration, and the growth, physiological indexes and Cd accumulation of Sedum aizoon L. under different treatments were measured. The results showed that: GMA fungi significantly increased the growth and biomass of Sedum aizoon L.; GMA and GM fungi significantly increased the proline content of Sedum aizoon L.; GMA and BEG168 fungi significantly reduced the Cd content of roots, stems and leaves. Therefore, under the Cd stress, inoculating GMA fungi can not only significantly improve the growth, biomass, but also significantly reduce the content of Cd in various parts of Sedum aizoon L., which has a certain value in practical production.
