Phytotranslocation of Fe by biodiesel plant Jatropha curcas L. grown on iron rich wasteland soil

Abstract

Experiments were conducted to evaluate the plant tolerance to Fe and its phytotranslocation by Jatropha curcas L. from an iron rich wasteland soil. The soil was collected from wasteland soil (WLS) of a small town Sandila, (Hardoi, U.P.) India, and three Jatropha clones were cultivated in WLS amended or not with sand or cowdung in a ratio of 3:2. The WLS had high pH, elevated electric conductivity (EC) and was rich in organic carbon and total NPK. Iron and Mn were 2-3 folds higher than that in the normal field soil. Net root and shoot elongation as well as fresh and dry biomass of the plants were only slightly affected at 100 d in WLS as compared with that grown in non-polluted soil. Tolerance index (TI) of J. curcas was significantly higher in cowdung amended WLS in comparison to that in WLS, or WLS amended with sand. Translocation factor (TF) from the soil to plants for Fe was significantly higher in WLS than that in the normal field soil. Bio-concentration factor (BCF) and concentration index (CI) for Fe were 0.12 to 0.37, 1.0 to 6.2 respectively. The results indicate that Jatropha plantation is suitable for phytoremediation of Fe-contaminate wasteland soils, and also that these polluted fields could be used to cultivate this important biodiesel plant species.

Utility of Jatropha for Phytoremediation of Heavy Metals and Emerging Contaminants of Water Resources: A Review

“…Similar studies were undertaken by Ghavri and Singh to expound the endurance of J. curcas L. to Fe and its phytotranslocation by the plant from a Fe‐rich marginal soil. A higher TF in wasteland soil than normal field soil as well as bio‐concentration factor and concentration index, CI, of 0.12–0.3 and 1.0–6.2, respectively, indicated the potential of J. curcas L. to remediate Fe‐contaminated soils.…”

The phytoextraction potential of selected vegetable plants from soil amended with oil palm decanter cake

“…This is could be attributed to the different physiological mechanisms and graft incompatibility in solanaceous plants (Kawaguchi et al 2008). In a similar study, the translocation factor of Fe for Jatropha curcas clones was higher in plants grown in the control soil than in the treatment plants (Ghavri and Singh 2010). Plants with both bioconcentration factor and translocation factor greater than 1 (TF and BCF [ 1) have the potential to be used in phytoextraction (Yoon et al 2006).…”

“…A high translocation of iron (TI = 0.5-1.6) in jatropha grown in wastelands contaminated with iron were determined by Ghavri et al (2010). Lower Silesian Voivodeship by Kucharzewski & Nowak (2004) Researches have been carried out so far have not showed any essential lead functions in living organisms.…”
