Production of plant growth regulators by some Fusarium species

|January 1, 1983
Abstract:
About 10 species of Fusarium were screened and tested for their growth regulatory activity on oat coleoptile straight growth test. Culture filtrates of four species contained growth-stimulating factors while others showed growth-inhibition responses on oat sections. On the whole, F. moniliforme was found to be produce higher stimulatory effects. Chromatographic analysis revealed the presence of several indole auxin and gibberellin-like plant-growth regulators in their culture filtrates. The quantity and biological activity of each indole spot was also measured.
