Gibberellin-like substances were found to be produced by fungi isolated from mycorrhizae of pine. Among the isolates studied gibberellin-like substances producers were most numerous among the Basidiomycetes forming ectotrophic mycorrhiza and among non-sporulating fungi forming no mycorrhiza. In most strains the gibberellin-like subtances were elaborated after 10--20 days of incubation. The Rf values of the gibberellin-like compounds were different in various strains, but in most of them substances showing gibberellin activity appeared on the chromatograms run with benzene, acetic acid (10:3 v/v) at Rf 0.2--0.6.
