Abstract
Heavy metal pollution of soil is a significant environmental problem and has its negative impact on human health and agriculture. Treatment of cowpea (Vigna unguiculata (L.) Walp) with different concentrations of chromium (III) oxide (Cr2O3) decreased the germination and early growth of plants. This effect was dose-dependent and was more significant at higher doses of Cr2O3. Chromium trioxide application significantly retarded germination, morphological and biochemical parameters compared to untreated control plants. Application of Pseudomonas fluorescens reduced the inhibitory effect of Cr2O3 by increasing the germination vigour at various level of concentrations. These results help to understand possible use of Pseudomonas fluorescens in bioremediation.
