Abstract

Yield and cadmium (Cd) content of Arabidopsis halleri ssp. gemmifera were investigated by field experiments in Andisols at two Cd concentrations for three years. The results were as follows: (1) Dry weight of the harvested plant (above-ground part) did not vary significantly for three crops in each field. (2) Cd yield of the harvested plant (above-ground part) for each crop was 927-1,408 g·ha-1 in field A (soil Cd content: 4.9 mg·kg-1) and 122-259 g·ha-1 in field B (soil Cd content: 1.4 mg·kg-1). Cd phytoextraction ability of this plant was similar to that of other phytoextraction plants in Japan, as determined in previous studies. This result showed that Arabidopsis halleri ssp. gemmifera is a promising candidate for phytoextraction of soil Cd. (3) Experimental results on soil Cd changes suggest that the applicability of phytoextraction using this plant is high for slightly Cd-contaminated Andisols. (4) Phytoextraction with Arabidopsis halleri ssp. gemmifera is a viable option for remediation of Cd-contaminated Andisols.
