Abstract Effects of N6-benzyladenine, kinetin, zeatin, N6-benzyladenosine, kinetin riboside, zeatin riboside, jasmonic acid, indole-3-acetic acid, indole-3-butyric acid, indole-3-propionic acid, abscisic acid and gibberellic acid on proliferation of hyphae of arbuscular mycorrhizal (AM) fungus Glomus fistulosum were studied under axenic conditions in vitro. The growth of intraradical hyphae of G. fistulosum was fully suppressed by 30 µM indole-3-acetic acid, but a perceptible decrease in the proliferation of the hyphae was observed already at 3 µM. Because such concentration is near the concentrations common in root tissues in vivo, the effect may be biologically significant. Similar effect was also observed for Glomus mosseae. Inhibitory effects of abscisic acid and cytokinins occurred only at very high, non-physiological concentrations. Ribosylated cytokinins showed stronger inhibition effects than their non-ribosylated counterparts. No stimulation of proliferation of hyphae by any plant hormone tested was observed.
