Abstract

The effect of ammonium sulphate supply on plant Cd uptake, growth and photosynthesis of bean plants (cv. Limburgse vroege) grown in Cd-contaminated artifi cial soil was studied. The experiments were performed at controlled conditions in absence or presence of Cd (0 or 50 mg Cd kg-1 soil) and with or without supply of ammonium sulphate [0 or 0.687 g (NH4)2SO4 kg-1]. Cadmium inhibited both growth and photosynthetic activity of bean plants. The supply of ammonium sulphate had no signifi cant effect on plant Cd uptake and growth inhibition, but to some extend, reduced Cd-induced stress and its negative impact on the photosynthetic performance.
