Abstract

NADH oxidation and cytochrome c reduction rates in the electrontransport chain were determined for mitochondria isolated from leaves of matureEuropean black alder (Alnus glutinosa L.) and exposed to arange of concentrations of the growth retardants flurprimidol andpaclobutrazol.NADH oxidation and cytochrome c reduction were enhanced by low concentrationsofboth compounds whereas higher concentrations reduced electron transport. Thisisthe first report of gibberellin synthesis inhibitors affecting electrontransport in plant mitochondria and provides evidence for another potentialmodeof action of this type of growth retardant.
