Influence of gibberellins on flower formation in Hyoscyamus niger L.

Jan Kopcewicz, Gabriela Centkowska

Abstract


Gibberellins (GA4+7) and gibberellin-like substances isolated from generatively induced black henbane (Hyoscyamus niger> L.) bring about the growth of shoots and a partial differentiation of axillary meristem in black henbane plants grown under non-inductive light conditions. Long-lasting application of gibberellins, however, did not result in full development of flowers in the majority of the plants investigated. Thus, it seems, that gibberellins are not specific flowering hormones in black henbane - a long-day plant.
