Abstract
The cultivation of cocoa (Theobroma cacao L.) is one of the most important crops in Ecuador. However, the presence of heavy metals in the soil is of concern, with cadmium (Cd) being one of the most worrisome contaminants, and its presence in the kernel has become a limiting factor for export. This work aimed to determine the capacity of arboreal plants to extract Cd.
Therefore, nine species were evaluated in sandy-frank soil with 2.4 % MO and a pH of 6.2, contaminated with 3 mg/kg of Cd. The variables evaluated were dry matter, soil and rhizosphere pH, Cd concentration and content, and translocation factor. The weed species that showed high adaptability and absorbed significant amounts of Cd were Pseudelephantopus spiralis, Oplismenus burmannii, Geophila macropoda, and Ipomoea grandifolia. In contrast, Commelina difusa,
Pseudelephantopus spiralis, Cissus verticillata, Epipomoea verticillata, and Epipremnum aureum functioned as metal stabilizers, indicating that they can be considered as hyperaccumulators of Cd, facilitating its safe removal from the soil.
