The heavy metal tolerance in corn (Zea mays L.)var. ‘Neelum’ was assessed at germination and seedling growthafter having subjected it to different concentrations of CuSO4and ZnSO4. Germination was not affected by any of themetal tested, whereas initial growth was strongly inhibited by increasing concentrations of ZnSO4. Seedlings developed toxicity symptoms in the presence of both metals but more chlorotic and necrotic regions were observed at varyinglevels of ZnSO4than CuSO4. The metal accumulation was concentration dependent. Z. mays seedlings accumulated more copper in roots but greater contents of zinc in their shoots. On the basis of results presented here, it can be concluded that the cultivar of the species tested has shown a marked sensitivity to the presence of small amounts ofmetals present in the growth medium. The data support the assumption that metal sensitivity is probably due to strongtendency of the species to accumulate them. This justifies that the corn variety ‘Neelum’ is not suitable for the cultivationunder situations where water and soil suffer from occasional and/ or transitory metal pollution.
