ABSTRACT
Lead and cadmium accumulation examined in shoot and leaf tissues of seedlings of mustard (Brassica juncea cv RH-30), at 7th day, treated with either putrescine (1 mM), or ammonium nitrate (10 mM) or IAA (10 microM). These were included in the nutrient medium, containing Pb or Cd (0.1 mM and 2 mM). Metal accumulation was more in shoot than in leaf tissues, which was increased manifold under saline conditions. However, Cd accumulation in tissues was higher than Pb. Chemical (putrescine, ammonium nitrate or IAA) treatment of the seedlings, decreased metal accumulation in leaf (10-20%) and in shoot (40 to 60%) tissues, depending upon external metal levels. Putrescine significantly decreased the metal accumulation and translocation under saline conditions.
