title: Auxin and gibberellin-like substances synthesis by Fusarium isolates pathogenic to corn seedlings.
abstract: The four isolates studied produced considerable amounts of auxin in media with tryptophan and two of them produced also considerable amounts in tryptophan-free media. The quantity of auxin synthesized increased with decreasing pathogenicity of the fungi. All of them produced also considerable amounts of gibberellin-like substances. There was no clear reaction between the production of the above substances and the pathogenicity.
