The growth of pakchoi was significantly inhibited under the condition of 0.3 mmol/L Pb stress. The treatment 0.1 mmol/L salicylic acid (SA) could significantly alleviated the growth toxicity of pakchoi seedling under the 0.3 mmol/L Pb stress. The effect of SA treatment on the growth of pakchoi under Pb stress showed the ‘low to promote and high to suppress’. The treatment 1.5 mmol/L SA did not alleviate the toxicity but increased toxicity. This may be related to the compound injury formation of high concentrations of SA and Pb.
