| Abstract: | Pot-culture experiments were carried out to study variety difference of lead accumulation and translocation in 15 Chinese cabbage cultivars, which aimed to screen out Chinese cabbage cultivars with low Pb accumulation. There was significant variety difference (P0.05) under different Pb treatments, which indicated that Chinese cabbage cultivars showed tolerance to Pb toxicity to a certain extent. Based on Pb concentration in aboveground parts, the TF and tolerance to Pb, Diyichunbao was considered as the potential cabbage cultivar with low accumulation of Pb. |
| Keywords: | Chinese cabbage (Brassica peckinensis L ) lead accumulation and translocation variety difference |
