THE EFFECT OF PHOSPHORUS IN THE FEEDING SOLUTION ON THE HEAVY ELEMENTS ACCUMULATION IN DIFFERENT PARTS OF WHEAT PLANT Triticum aestivum

The study was carried out to show the effect of phosphorus in the feeding solution on the heavy elements accumulation like (cadmium and mercury ) in the different parts of wheat plant (roots , green parts and seeds) .The seeds type Ibaa 99 were planted in containers consist of sand soil washed with distilled water to be clean from heavy elements . Then, the seeds were watered with feeding solution of different concentration of phosphorus (0,17,34,68) mg/liter with cadmium (50,100) mg/liter or mercury (50,100) mg/liter. The results showed that (17) mg/liter phosphorus factor reduced the accumulation of the heavy elements of mercury and cadmium in the different parts of the plant (roots , green parts and seeds ) as compared with other phosphorus factors
