Several factors affecting the growth and the uptake of cadmium by
okra plants were studied using both root ‐ treatment and foliar ‐
treatment. These factors were the concentration of cadmium , type of
treatment, soil composition, presence of foreign ions, salinity, acidity
and temperature.
Both growth of plant and cadmium
uptake by plant were affected highly by the concentration of cadmium,
type of treatment, soil composition, salinity and temperature. Acidity
of solutions has only a little and irregular effect. A synergistic
combined effect of lead, copper and zinc with cadmium was observed on
the growth of plant but not regular on the uptake of cadmium.
