ABSTRACT: The aim of the
investigation was to determine the potential
effect of lead on maize growth. Lead is considered as important potent
environmental contaminant. Various ecological, environmental and evolutionary
processes in the microsphere are disrupted because of lead toxicity to the microbial
community. The effects of Lead Nitrate (Pb(No3)2) as
heavy metal on germination, early growth seedling, root-shoot length, root-shoot
fresh and dry weights, total protein content and the uptake of lead by roots
and shoots of Zea-mays were
investigated. All of the parameters were reduced by the increased lead concentrations. Such growth retardation was due to
metals toxicity that resulted in damages to various physiological and
biochemical processes.
