Evolution der Gärungskapazität in den flut- und anoxiatoleranten Rhizomen von Phalarisarundinacea, Phragmites communis, Schoenoplectus lacustris und Typha latifolia

Abstract

Rhizomes of some flooding and anoxia tolerant helophytes (Phalaris arundinacea, Phragmites communis, Schoenoplectus lacustris and Typha latifolia) show an increased fermentation capacity following a 4 d treatment with N2 compared to the aerated controls. This increase is much smaller in comparison to dry land plants susceptible to an 02 deficit stress. The significance of this finding is discussed with respect to the current metabolic theory of flooding tolerance
