title: Production of gibberellin-like substances by bacteria and fungi isolated from the roots of pine seedlings (Pinus silvestris L.).
abstract: The production of gibberellin-like substances by bacteria and fungi was investigated. A considerable number of the microorganisms studied produced these substances (55 and 86% of bacterial and fungal isolates respectively). Most of the organisms tested synthesized biologically active substances located on the chromatograms with the solvent system benzene, acetic acid (10:3 v/v) at Rf 0.05--0.3. The ammount of gibberellin-like substances produced varied in the range 0.00007--0.00065 GA3 equivalents mug/ml in bacteria and 0.00014--0.00118 mug/ml in fungi.
