Marsh plants rhizomes in their natural habitat accumulate before outgrowth in early spring large amounts of arginine (Acorus calamus) or asparagine (Phragmites australis, Schoenoplectus lacustris and Typha angustifolia).

Anoxic treatment for 10 d lowers the amino acid content in rhizomes of P. australis and T. latifolia. Only the concentrations of γ-aminobutyric acid and alanine increase. A. calamus shows a different behaviour. There, most of the amino acids slightly increase. Arginine is still predominant under anoxia compared with γ-aminobutyric acid and alanine.

The results are discussed in relation to protein mobilisation and rhizome survival strategies. In addition, the investigations exhibit marked physiological differences between anoxic and flooded conditions.
