The fern Asplenium nidus L. is in great demand as an ornamental plant. The aim of this work was to investigate the influence of phytohormones in promoting a gametophytic and sporophytic growth in homogenized sporophytes tissue. Exogenous application of 0.5 and 5 µM N⁶-benzyladenine, 0.05 and 0.5 µM indole-3-acetic acid (IAA), and 0.3 and 3 µM gibberellic acid (GA3) favoured sporophyte regeneration, whereas gametophyte regeneration took place when plant material was cultured in a hormone-free liquid MS medium. The endogenous contents of the auxin IAA, the cytokinins trans-zeatin, transzeatin riboside, dihydrozeatin, dihydrozeatin riboside, isopentenyladenine and isopentenyladenosine, and the gibberellins GA₁, GA₃, GA₄, GA₇, GA₉ and GA₂₀ in growing gametophytes and sporophytes were evaluated. Similar levels of the auxin and cytokinins and qualitative differences in the gibberellins were found between both generations.
