Changes in the amount of proteins in seeds and stems cells of seedlings of Maize Plant (Zea mays L.) cultured in solutions of some heavy metal salts

The aim of this research is to determine the effect of some heavy metal ions on total protien metabolism in seeds and seedlings of maize plant (GHOTA 82) and study the changes in the morphological specifications of plant, after cultivating for 6 days in solutions at different concentrations of water and heavy metal ions Ni2+, Cu2+, Zn2+, Cd2+, Hg2+ and Pb2+. The results showed that heavy metal ions have inhibitory effect on total protien metabolism, which decreased their amount in seedlings, While accumulated in the seeds. This inhibitory effect depends on the type and concentration of heavy metal ions. The results also showed morphological changes in the maize plant seedlings, which decreased their growth due to the effect of these ions.
