Flowering in Lemna paucicostata 6746 could be induced by tannic acid under strictly non‐inductive photoperiods. This polyphenol completely abolished the photoperiodic sensitivity of strain 6746 as flowering could also be obtained under continuous light (nearly 80% flowering was recorded in the plants supplied with 10 −5 tannic acid). Though its mode of action is unknown, tannic acid is unlikely to act as a gibberellin‐antagonist in its effect on flowering in strain 6746.
