Phytoextraction and Cd Allocation to the Stem of Woody Species Used in Cacao Agroforestry.

ABSTRACT: Global cacao production, primarily led by African countries, is facing a crisis, which presents growth potential for South American countries like Colombia, Peru, and Ecuador. However, a significant challenge for these countries is cadmium (Cd) contamination in cacao beans. Agroforestry systems with cacao (CAFSs) improve soil health and can remediate Cd through tree phytoextraction. Effective phytoremediation requires Cd-tolerant, high-biomass species and preferential Cd allocation to stems. This study evaluated the phytoremediation potential of four forest species (Cariniana pyriformis Miers, Terminalia superba Engl. and Diels, Swietenia macrophylla King, and Cedrela odorata L.) under cadmium (Cd) exposure. C. pyriformis exhibited hypertolerance, showing
