Abstract 

[Purpose] The objective was to explore the correlated influence factors for growth, absorption accumulation of Pb by using different ways of roots interaction of Arabis alpina and Vicia faba.[Method] The content of lead in soil and plant was determined by atomic absorption spectrometry. A. alpina and V. faba roots interaction, including PVC board separated, a nylon mesh cloth separated, non separated. The effects of content of lead of A. alpina and V. faba were analyzed.[Results] (1) With no separated, the total microbial number of Arabis alpina and V. faba was found on variety no separated increased. (2) A high Pb accumulation of A. alpina was found on variety no separated and a low on variety PVC board separated;a high Pb accumulation of V. faba was found on variety PVC board separated and a low on variety a nylon mesh cloth separated. (3) Solution effects accounted for about 70% and root effects about 30%.[Conclusion] The role of the solution (root exudates and root symbiotic bacteria) should be the main reason to improve Pb accumulation of A. alpina and to reduce Pb accumulation of V. faba.
