A cross-inoculation study on indigenous rhizobia and selected tree legumes

Abstract

A cross-innoculation study with idigenous rhizobia was carried out on seven host legume species from where they were originally isolated. The legumes included Acacia albida, Acacia mearnsii, Calliandra calothyrsus, Leucena leucocephala, Prosopsis juliflora, Sesbania grandiflora and Sesbania sesban. The host plant species were varaibly promiscuous in their rhizobial assocaiates. Conversely rhizobia isolated from Sesbania grandiflora and Sesbania sesban were more specific with their host partners in terms of symbiotic effectiveness.
