Ethidium bromide, a DNA intercalating agent, acts synergistically with gibberellin on the elongation of cucumber seedling hypocotyls at concentrations of 0.05 and 1.0 μg per plant. At higher concentrations and when given prior to the GA treatment, ethidium bromide acts antagonistically with gibberellin.
