Sensitivity of selected crops to lead, cadmium and arsenic in early stages of ontogenesis
This paper examines the influence of Pb+2, Cd+2 and As+3 on growth of roots in legumes (broad bean, soybean, pea) and cereals (barley, maize). Roots of germinating plants were exposed to two different levels of Pb+2 (300 and 500 mg*L-1), Cd+2 (100 and 300 mg*L-1) and As+3 (50 and 100 mg*L-1) during...
