Carbohydrates and protein contents of wetland plant rhizomes (Acorus calamus, Glyceria maxima, Phragmites australis and Typha latifolia) are correlated with the requirements of energy and metabolites during specific plant regeneration and rhizome reconstitution at the natural site. Rhizomes without fully expanded and emersed shoots contain ethanol, indicating the occurence of fermentation. Fermentation capacity (ADH-activity) is adapted to the actual needs, depending on the development stages. During the same time span an accumulation of amino acids is detected. They do not originate from protein mobilisation, with the exception of Acorus calamus. The “de novo” synthesis of these amino acids could show the diversification of glycolytic end products under anaerobic conditions. Lactate fermentation of these wetland plants is of little importance in the energy yield from carbohydrates.
