Última Heavy metal accumulation in Pelargonium hortorum: Effects on growth and development Phyton Orroño,DI; Lavado,RS. Ornamental plants have been proposed for growing in heavy metal (HM) contaminated soils, and also for phytoremediation. We evaluated (1) biomass production and (2) HM accumulation in Pelargonium hortorum. Plants were grown for 16 weeks on HM (cadmium, chromium, copper, lead, nickel and zinc) enriched soils. Treatments were i) control, non-enriched soil, ii) medium concentration treatment, and iii) high concentration treatment. Four destructive harvests were carried out, and roots, stems, leaves, and flowers were analyzed each time. Concentrations of HM were determined using ICP. Significant reductions in biomass production were observed in HM-enriched soils compared with the control. Different indexes confirmed that P. hortorum was affected by HM. Heavy...

J. Plant Physiol. Ghavri,Surendra Vikram; Singh,Rana P.. 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...
