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 >or= 7.9 mg kg(-1) soil, while the productivity of chrysanthemum and gladiolus was sustained up to 21.2 mg kg(-1). DTPA-Cd for 50… CONTINUE READING
