An Assessment of Quaternary Ammonium and Related Compounds as Osmotic Effectors in Crop Plants

  • R. Gareth Wyn Jones
Part of the Basic Life Sciences book series (BLSC, volume 14)


In this paper I shall attempt to assess whether or not the accumulation of certain amino acids and their N-methylated derivatives, particularly glycinebetaine, is a specific adaption related to enhanced salt tolerance in, at least, some halophytic species. As a result I shall neglect other extremely important aspects of salt tolerance and toxicity but these have been considered elsewhere (Wyn Jones, 1980; Wyn Jones et al, 1979).
