Chemical Composition of Australian Mangroves I. Inorganic Ions and Organic Acids
Young and old leaves from 22 mangrove species of Northern Queensland (Australia) were investigated for inorganic ions and organic acids. Na+ and Cl− concentrations expressed on plant water basis were close to sea water with the exception of Heritiera littoralis and Hibiscus tiliaceus, which are both regarded as brackish water species. Leaf age did not appear to effect Na+ and Cl− storage much. SO42− and Mg2+ increased markedly in old leaves of salt-secreting species such as Avicennia marina, Avicennia eucalyptifolia, Aegialitis annulata, Aegiceras corniculatum and Acanthus ilicifolius as well as in the members of the Rhizophoraceae.
Free oxalate was found in all salt-secreting species and young leaves of Lumnitzera racemosa. Malate and citrate were present in all species, while quinate and shikimate occurred frequently. The contribution of organic acids to the anion content was important in only a few cases.
Mechanisms of salt-regulation and problems in the classification of mangroves are discussed.
