Induction and promotion of flowering by heat-treated catecholamines in Lemna paucicostata.
Alkali- and heat-treated norepinephrine, a catecholamine, induced flowering of short-day (SD) plant Lemna paucicostata 151 even under long-day (LD) conditions. Flowering induced with a lower concentration of heat-treated norepinephrine was promoted under SD conditions but inhibited by a night break. The related compounds L-dopa and dopamine also promoted flowering under SD conditions when they were heat-treated.
