Arbuscular mycorrhizal association and foliar nutrient concentrations of cupuassu (theobroma grandiflorum) and guaraná (Paullinia cupana) plants in an agroforestry system in Manaus, AM, Brazil

Arbuscular mycorrhiza can be important for plant nutrition in acid and low fertility soils such as those of the Amazon. The present study evaluated the mycorrhizal colonization by native arbuscular mycorrhizal fungi (AMF) and nutrient concentrations of cupuassu and guarana leaves in an agroforestry...

The present study evaluated the mycorrhizal colonization by native arbuscular mycorrhizal fungi (AMF) and nutrient concentrations of cupuassu and guarana leaves in an agroforestry system in Manaus, Amazonas State, Brazil. Ten plants of each species were selected, of which the roots, soil and leaves were sampled during the rainy and dry seasons. Guarana and cupuassu trees presented higher levels of AMF colonization during the rainy season. Ca, Mg, K, P, Zn, Cu, and Mn concentrations in both species were not affected by the season. Fe concentration was higher during the rainy season in the cupuassu leaves, but higher in the dry season in the guarana leaves.
