摘要: We investigated the effectiveness of Nitroxin inoculation on lead (Pb) and nutrient uptakes by little seed canary grass. The factors tested included (or not) with different soil concentrations Pb (0, 200, 400 800mgPbkg-1 soil). Increasing decreased stem, leaf root dry weights. Shoot phosphorus increased in parallel increasing concentrations. did not alter concentration roots. translocation factor was >1 inoculated treatments range 200 to 400mgkg-1; for 800mgPbkg‑1 no was, however, <1. Our results indicated that bioaccumulation grass <1, indicating it is a excluding plant.
