摘要: Glomus mosseae, a representative species of Endogonaceae (Phycomycetes) able to form vesicular-arbuscular mycorrhiza, was investigated for phytohormone production. Spores G. mosseae were axenically germinated in water, and the resultant mycelial growth assayed by standard procedures extracting plant hormones from microbial cultures. Paper partition chromatography specific bioassays used separate identify growth-regulating substances. The microorganism synthesized at least two gibberellin-like substances, one with R(f) corresponding position authentic gibberellic acid, four substances properties cytokinins.
