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 d
ays 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.
