Abstracts |
The objective of this work was to evaluate the arbuscular mycorrhizal colonization in peach palm (Bactris gasipaes Kunth) and cupuaqu (Theobroma grandiflorum (Willd ex Spring) K. Schum), in agroforestry systems and monoculture in the Central Amazon region, and to identify anatomic characteristics of mycorrhizal colonization in these species. Soil and root samples were collected in the field, in the dry and rainy season. Mycorrhizal root colonization of cupuaqu and peach palm is affected by the management systems, with higher colonization rates in the monoculture system. Total spore density of the arbuscular mycorrhizal fungi under cupuaqu is not affected by management systems or season, but under peach palm this variation is season dependent. Mycorrhizal colonization of Arum and Paris types occur in peach palm, and only Arum type occurs in cupuaqu. |
