Physiological Effects of Copper on Some Biochemical Parameters in Zea mays L. Seedlings

Latifeh Pourakbar, Masoud Khayami, Jalil Khara and Tayabeh Farbodnia

Abstract:
Growth parameters and biochemical changes were studied in roots and leaves of 15 day old maize grown in a nutrient solution containing various copper concentrations (0, 25, 50, 75 and 100 μM). An accumulation of H2O2 was observed in roots and shoots. The leaf chlorophyll a, b and carotenoid contents decreased with increasing Cu concentration. The results demonstrated adverse effects of Cu on N metabolism and plant growth. Cu exposure elevated Cu concentration and decreased Nitrate Reductase (NR) activity in the roots and shoots. However, Cu exposure increased total free amino acid content in the leaves.
