The role of cyanobacteria in the pollutant soil of remnants oil and cultured by wheat Triticum aestivum type Noor seeds

Abstract

The present study measured some of physiological factors resulting from the pollution of the soil by different concentrations of oil residue and planted with the wheat type Noor, from 2005 – 2006 and it is added some types of nitrogen fixing cyanobacteria.From this study a result has been show that oil residues affected in two contrasted points. The first effect led negatively to the prolonged plant to the normal situation compared with the control group. Chlorophyll-b are less sensitive upon the pollution than the Chlorophyll-a in concentration 8000 ppm and we have also inferred that the increase in quantity of cyanobacteria was affected negatively because it causes the increase on nitrogen fixing which has an impact on the physiology operations of the plant.
