Abstract

We investigated the effects of catecholamine on flower-induction in P. nil (cv. Violet). GCSIM analysis identified dopamine for the first time in P. nil seedlings. Dopamine levels in the cotyledons did not show a significant change during the inducing dark treatment. The dopamine content of cotyledons exposed to various durations of darkness were 0.1-0.2 nmol/ g fresh weight. The same content was found when cotyledons were exposed to continuous light.
