Optimizing the phytoextraction potential of Eleusine indica L. Geartn in Lead (Pb) contaminated soil
Keywords:
Phytoextraction, contamination, Eleusine indica, Lead, transplantingAbstract
Optimizing the phytoextraction potential of Eleusine indica was investigated at three levels of Pb pollution treatments (50 ppm, 100 ppm, 200ppm) and a control in a completely randomized design. Each treatment and the control were replicated thrice and allowed for 12 weeks under natural environmental conditions, one stand each of the test plant were transplanted into the experimental units. Statistical analyses of results showed morphological changes - plant shoot F-value (2.87) is lower than critical value (3.14), plant root F-value (98.9) is higher than critical value (5.64), plant heights F-value (2.7) is lower than the critical value (3.16). Phytoextraction potential of bioconcentration factor (BCF) and translocation factor (TF) results showed that Eleusine indica, extracted substantial concentration of Pb in the above plant biomass (shoot): which are 4.9, 19.35, and l5.1 mg/kg and root: 12.68, 82.3 and 82.25 mg/kg at 50 ppm, 100 ppm and 200 ppm respectively. Levels of Pb absorbed in the roots and shoots after 12 weeks showed that more bioavailable pool of Pb was not translocated from the roots to shoots. The result showed that the plant have a low phytoextraction potentialDownloads
