RESUMO

The research was carried out in the qualitative and quantitative composition of free and conjuted forms of gibberellin-like substances (GLS) in sterile and fertile tallies of the green freshwater ale Chara contraria A. Br. The levels of GLS in oospores, rysoids, two lower internodes were studied in leaves of both middle and apical parts of the fertile thalli of the algae. It was found that the leaves of the upper part of the main stem of the reproductive chara thalli are characterized with high gibberellin content (due mainly to the bound forms).
