Six provenances of Acacia auriculformis have been tested for their
ectomycorrhizal dependency with 2 indigenous strains of Pisolithus sp.
Moreover the endomycorrhizal and rhizobial symbiosis, the multiplication
of plant parasitic nematodes have been quantified. The results showed
significant variations in the growth rate between provenances. The both
compatibility and dependency with the ectomycorrhizal strains were also
different among the provenances. Three main genera of nematodes have
been identified with, in particular, S. cavenessi which is one of the
most pathogenic nematode of soudano-sahelian crops. Endomycorrhizal
structures were sometimes detected on the root systems but no nodules
have been observed for all the provenances. The use of these A.
auriculiformis provenances in an agroforestry system was discussed.
