摘要：Heavy metal pollution of soil is a significant environmental problem and has its negative impact on humanhealth and agriculture. Treatment of cowpea (Vigna unguiculata (L.) Walp) with different concentrations ofchromium (III) oxide (Cr 2 O 3 ) decreased the germination and early growth of plants. This effect was dose-dependent and was more significant at higher doses of Cr 2 O 3 . Chromium trioxide application significantlyretarded germination, morphological and biochemical parameters compared to untreated control plants.Application of Pseudomonas fluorescens reduced the inhibitory effect of Cr 2 O 3 by increasing the germinationvigour at various level of concentrations. These results help to understand possible use of Pseudomonasfluorescens in bioremediation.
