To evaluate the production potential and Cd removal by three flower crops, viz.: marigold (Tagetes erecta), chrysanthemum (Chrysanthemum
indicum) and gladiolus (Gladiolus grandiflorus), an experiment was conducted on differentially contaminated soils (DTPA-Cd
0.6–68.4 mg kg 1). Biotoxicity of Cd lead to reductions in growth and flower yield of marigold at DTPA-Cd P7.9 mg kg 1 soil, while
the productivity of chrysanthemum and gladiolus was sustained up to 21.2 mg kg 1. DTPA-Cd for 50% yield reduction (C50) was 85, 106
and 215 mg kg 1 soil for marigold, chrysanthemum and gladiolus, respectively, that indicates a better Cd-tolerance in gladiolus. The
uptake of Cd increased with contents in soils and the maximum accumulation occurred in leaves. Among the economic parts, gladiolus
spikes accumulated the highest Cd (7.2) followed by flowers of marigold (6.5) and chrysanthemum (4.0 mg kg 1). But, because of higher
biomass, the total Cd removal was the maximum with chrysanthemum (8.3) followed by gladiolus (6.0) and the minimum (2.6 mg m 2)
with marigold. Gladiolus with highest tolerance and Cd-content in saleable part holds potential to clean up the moderately contaminated
soils.
