Abstract
The culture filtrates of the rhizosphere fungi of broad bean (Vicia faba L.) and cotton (Gossypium barbadense L.) were analysed for the presence of plant growth substances of auxin and gibberellins nature. Bioassay test and chromatographic analysis indicated that these fungi, each synthesized different auxins in their culture medium. These auxins were indole compounds. Similarly the rhizosphere fungi produced in their culture medium some gibberellins and gibberellin-like substances.
Abstract
Byly analysovány rostlinné růstové látky typu auxinů a giberelinů u filtrátů tekutých kultur hub vyskytujících se obvykle v rhizosféře bobu (Vicia faba L.) a bavlníku (Gossypium barbadense L.). Biologickými testy a chromatografickou analysou byly nalezeny u všech studovaných hub různé auxiny—indolové sloučeniny a rovněž některé gibereliny a giberelinu podobné látky.
