Sensitivity of selected crops to lead, cadmium and arsenic in early stages of ontogenesis

2015, 16 (4)   p. 476-488



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 four day experiment. During this time, length of roots were daily measured. Toxicity of metal treatment on plant roots was calculated as phytotoxicity index (IP). In all cases, a moderate effect of lead treatment was observed (IP up to 56.67 %) while higher doses of cadmium and arsenic resulted in increase of IP above 50 %. In cases of barley and maize, the toxic effect of almost all test doses of the heavy metals was observed as soon as 24 hours after their application. Generally, a higher tolerance to tested metals showed roots of both bean cultivars (IP 16.27- 69.53 %), while the most sensitive reactions had roots of barley and soybean (IP > 50 %, excluding dose Pb 300).
