Flower-inducing factors in extracts of flowering Lemna gibba G3 were investigated using Lemna paucicostata 151 as the bioassay plant. Fractions with flower-inducing activity were obtained after several purification steps. Two of the active substances were identified as L-pipecolic acid and nicotinamide by MS and NMR analyses.

Both L-pipecolic acid and nicotinamide exhibited flower-inducing activity in L. paucicostata 151 grown on one-tenth-strength M medium containing benzyladenine, the former being ten times as active as the latter. L-Pipecolic acid was active even at 0.01 ppm (7.8 × 10–8 M). The effect of L-pipecolic acid on flowering strongly depended upon the presence of exogenous cytokinin. The coexistence of cytokinin seemed to be essential for L-pipecolic acid to exhibit flower-inducing activity. In contrast, the effect of nicotinamide on flowering was basically the same as that of benzoic acid or nicotinic acid.
