摘要: Abstract Cadmium (Cd) easily accumulates in tobacco, which endangers public health through Cd exposure from smoking. However, its uptake, translocation, and distribution tobacco plants during plant development or response to biochar application are poorly understood. A pot experiment was conducted with (Yunyan 87) grown soil severely contaminated (30 mg kg−1) amended 0, 1, 2% (w/w) stem-derived (BC). The absorption accumulation of all parts the were most active rosette stage fast growing stage, approximately 90% deposited leaves occurred, especially lower leaves. concentrations without added decreased significantly by 52.61–78.30% due rapid increase biomass (dilution effect), although concentration increased 48.89% (P
