Preferred Abstract (Original):

Several factors affecting the growth and the metal uptake of pepper plants treated with cadmium solutions have been studied. These include concentration of cadmium, type of treatment, type of soil, plant species, and some properties of solutions used for treatment such as acidity, degree of salinity and temperature.
Cadmium had an obvious effect on the growth of pepper plants. Foliar‐treated plants were affected more than root‐treated plants. The least degree of growth‐inhibition and of cadmium uptake was found in plants grown in soils with high organic matter content. Various species of pepper plants acted very differently towards cadmium treatment. Both growth‐inhibition and cadmium uptake was increased in plants treated with acidic, saline and hot solutions.

Preferred Abstract (Original):

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.

Preferred Abstract (Original):

In this study the effects of root and foliar treatments of marrow plants with cadmium and lead solutions on the growth of the various parts of plant (roots, stem, leaves and fruits) have been studied. Growth inhibition of the various parts of treated plants has been compared with each other and for the two types of treatment. The toxicity of cadmium on the growth of plant has been compared with the toxicity of lead on the various parts of plants treated by root or by foliar‐treatment with metal ions.
Cadmium and lead uptake by plants and the distribution of this uptake between the various parts of treated plants have been determined and commented on.
Percentages of cadmium or lead taken by plant from the total amount of cadmium or lead added during treatment have been calculated and found to be very small. This percentage has been found to be higher in foliar‐treated plants and from dilute solutions than in root‐treated plants and from more concentrated cadmium or lead solutions.
