Abstract: | Lemna paucicostata 6746, a short-day plant, flowers in agedHutner's medium even under continuous light, when the endogenousnitrogen level decreases to below 1.6 µmg fr wt. At thesenitrogen levels, daylength-independent flowering of the plantcan be induced even in fresh Hutner's medium. Thus, old-cultureflowering in Hutner's medium is due to nitrogen deficiency inthe plants.
