概要
- 論文の詳細を見る
Flowering of Lemna paucicostata 441 (P441), a sensitive short-day plant (SDP), was promoted under a near critical photoperiod by the crude water extract of the same plant added to the medium. The extract induced flowering in L. paucicostata 151 (P151), a weakly responsive SDP, under continuous light. The activity for P151 was greatly promoted by simultaneous application of benzyladenine, and the extract of only 0.3 mg fr wt plant added to 10 ml of assay medium with 1 μM benzyladenine was active. Active substance(s) was similarly obtained from both flower-induced and non-induced plants, and more or less from all species and strains of Lemna tested, including P151. However, the extract of short-day strains was more active than that of L. gibba G3 (G3), a long-day strain. G3 responded only slightly to the extract of either P441 or G3, whereas P151 responded far more strongly to the extract of P441 than to that of G3.
