Influence of Cadmium and Arbuscular Mycorrhizae on Growth and Chlorophyll Content in Theobroma cacao and Theobroma grandiflorum Plants

Advances in Agriculture, Volume 2026, Issue 1, 2026.
Inoculation of arbuscular mycorrhizal fungi (AMF) has important benefits, not only for plant growth but also for reducing Cd absorption in Theobroma plants. This study aimed to investigate the influence of cadmium (Cd) and arbuscular mycorrhizae (AM) on growth and chlorophyll content (CC) in Theobroma plants.
