โฆ Synopsis
In experiments conducted withA.flavus strains isolated from groundnut fields at different periods of the year, it was possible for us to show significant differences in the intensity of the toxigenesis of these micromycetes. These differences appear to be dependent on the evolution of the mycoflora during the growth of the plant.
