Microorganisms in the rhizosphere of useful tropical plants.
The cupuacu tree (Theobroma grandiflorum (wild. ex Spreng.) Schum.) and the pupunha tree (Bactris gasipaes H.B.K.) are grown trhoughout the Amazon region as part of orchards or small scale production systems. In a preliminary study the number of oligotrophic not nitrogen-fixing, oligotropic nitrogen-fixing bacteria and fungi associated with the root surface, soil in 2mm-10mm and soil in> 10mm-200mm from the root surface were assessed. The highest number of the culturable bacteria were associated with the rhizoplane. With greater distance from the root surface the total number of bacteria decreased.
