“…P. coronopus showed an unchanged top/root ratio. This observation is in agreement with data on Centaurium littorale, which occurs in salt marshes together with P. coronopus (Freijsen 1971). P. coronopus showed only small differences in R.G.R.…”

Growth of Plantago lanceolata L., P. media L. and P. coronopus L. was followed at two levels of mineral nutrition (low-salt and high-salt). In addition the response of transfer of plants from lowsalt conditions to high-salt conditions and vice versa was studied. Growth of these Plantago species was not much affected by the nutritional level. P. coronopus showed the least dependence on the level of mineral nutrition.The Ca^+-and Mg^^-stimulated ATPase activity of microsomal preparations of the roots of Plantago was also studied. A pH optimum at pH 6.5 was observed in all species, together with a relatively high ATPase activation by Mg^+ in P. lanceolata, by Ca^+ in P. media, and by both ions in P, coronopus. The specific activity of the ATPases was highest in preparations from low-salt roots.The three species all occur in relatively nutrient-poor habitats, but they are at the same time particularly adapted to circumneutral soils (P. lanceolata), to Ca^+-rich soils {P. media) and to alternating levels of mineral nutrition {P. coronopus). The properties of the ATPases {K^, V^^^, protein content) and the growth are discussed in relation to these ecological properties of the species.

“…These sandy saline areas, like fresh or brackish dune slacks are supposed to be deficient in nitrogen and phosphorus (e.g. Pigott 1968, Joenje 1971, Freysen 1971, and their productivity is considered to be low (Tyler 1971b). The characteristically zonated vegetation is dominated by many halophytes (Rozema 1975b), although typically nitrogen demanding halophytes from the Chenopdiaceae are lacking.…”

Stickstoffmineralisation in sandigen, salzhaltigen Marschböden der Niederlande Die jahreszeitlichen Veränderungen der Ammonifikation und Nitrifikation einer alkalischen Salzmarsch wurden untersucht. Ammoniumstickstoff war nicht vorhanden. Bedingt durch den geringen Gehalt an organischem Material bleiben die Nitratgehalte ebenfalls niedrig. Die jahreszeitlichen Schwankungen der aktuellen und der durch Inkubation erhaltenen Nitratmengen werden teilweise durch den Temperaturverlauf verursacht; doch dürften andere Faktoren ebenfalls eine Rolle spielen, wenn auch die nitrifizierenden Bakterien an mittlere Salzgehalte angepaßt sind. Insgesamt gesehen wird die Vegetationsentwicklung der sandigen Salzmarsch durch das geringe Stickstoffangebot nicht gefördert, und die Vegetationszonierung ist unabhängig vom Stickstoffhaushalt.

Seed and transplanted adult plants from populations of Festuca rubra, collected from inland, salt-marsh and sand-dune sites were grown on culture solution with added sodium chloride. The growth of the populations of the three habitats was reduced differentially by salt. The salt marsh ecotype Festuca rubra ssp. litoralis was only slightly affected and the inland ecotype F. rubra ssp. rubra was severely retarded at 60 mM NaCl. The dune ecotype F. rubra ssp. arenaria had an intermediate tolerance. The tolerant ecotypes accumulated less sodium chloride as compared to the sensitive ecotype, suggesting that salt tolerance is caused in part by salt exclusion.In addition, the dune ecotype F.r. arenaria appeared to be more drought tolerant than the salt marsh ecotype. Abscission of salt-saturated leaves does not function as an adaptation to salinity in Festuca rubra.All three ecotypes accumulated proline with increased salinity. The response was most pronounced in the drought tolerant F.r. arenaria, indicating that proline accumulation is a response to osmotic stress rather than to ion-specific effects of salinity. The observed differences in salt tolerance may be explained by differential sensitivity to toxic effects of sodium chloride.The occurrence on a beach plain of closely adjacent populations of F.r. arenaria and F.r. litoralis, differing markedly in salt tolerance, is briefly discussed.
