Abstract
Experiments were carried out to investigate the effect of Pb and Bi chelated by EDTA in nutrient solution medium on growth and Pb or Bi concentration of shoots and roots of Brassica Juncea. The shoot and root dry weight of B. Juncea under the condition of medium to which 100 μmol l-1 of Pb was given was almost equal to control. The Pb concentration of shoot of B. Juncea in 500μmol l-1 of Pb was 3.8 times higher than that in 100μmol l-1. B. Juncea under the condition of medium to which 100 μmol l-1 of Bi was given was decreased to 52-66 % of control. The Bi concentration of shoot of B. Juncea in 100μmol l-1 of Bi was almost equal to 50μmol l-1. It was considered that the decrease of growth in 500μmol l-1 of Pb was due to accumulate Pb in the shoot and root, but, that in 100μmol l-1 of Bi was due to accumulate Bi in the root. In this study, it was suggested that the growth of B. Juncea was inhibited by Pb and Bi in nutrient solution.
