Ž . We determined the feasibility of using salt-tolerant plants halophytes as biofilters to remove nutrients from saline aquaculture wastewater. Suaeda esteroa, Salicornia bigeloÕii and Atriplex Ž . barclayana Chenopodiaceae , species with potential as forage and oil seed crops, were grown in Ž . sand in draining containers lysimeters in a greenhouse experiment. They were irrigated to meet evap...

There is considerable variability in salt tolerance amongst members of the Triticeae, with the tribe even containing a number of halophytes. This is a review of what is known of the differences in salt tolerance of selected species in this tribe of grasses, and the potential to use wild species to improve salt tolerance in wheat. Most investigators have concentrated on differences in ion accumu...

Soil salinity is generally spatially heterogeneous, but our understanding of halophyte physiology under such conditions is limited. The growth and physiology of the dicotyledonous halophyte Atriplex nummularia was evaluated in split-root experiments to test whether growth is determined by: (i) the lowest; (ii) the highest; or (iii) the mean salinity of the root zone. In two experiments, plants ...

Chloride (Cl-) has been related to increased phytoavailability of cadmium (Cd) in soil. A glasshouse experiment using a historically contaminated soil was undertaken to evaluate the effect of chloride on Cd uptake by salt-tolerant plants and possibly quantify the uptake of discrete Cd species (e.g. Cd2+, CdCl+, CdCl(0)2). Chloride treatments were applied as 100 mM NaCl and compared with equival...
