Effect of Heat-Treated Noradrenaline on Flowering in Lemna

Abstract

In a previous study, heat-treated noradrenaline induced flowering of the short-day plant Lemna paucicostata Hegelmaier 151. In the present study, we found that heat-treated noradrenaline also had flower-inducing activity in short-day L. paucicostata strains 441 and 6746 and in long-day L. gibba strain G3. The flower-inducing activity in these plants was enhanced by water homogenates of eggplant (Solanum melongena L.).
