abstract:
The experiment was conducted to measure the impact of pollution with lead and cadmium on early growth of maize. During 14 days of the laboratory experiment the daily increases of plant height, leaf area, plant mass, root length and thickness were measured. Maize was growing in water solutions of various concentrations of lead or cadmium, and in mixture of lead and cadmium. Overall maize growth was affected by lead and cadmium, however different impact of these metals according to their concentrations was observed. Lead and cadmium toxicity was the most apparent for root length, especially for thin roots. Root growth inhibition was stronger by cadmium than by lead for low heavy metals concentrations, and an inverse relation was observed for the highest concentrations.
