Control of salt transport form roots to shoots of wheat in saline soil

Husain, Shazia; von Caemmerer, Susanne; Munns, Rana Ellen

Description

Wheat genotypes with 5-fold difference in shoot Na+ concentrations were studied over a salinity range of 1-150 mM NaCl and CaCl 2 of 0.5-10 mM to assess their performance in saline and sodic soils. All genotypes had a maximum shoot Na+ concentration at 50 mM external NaCl when the supplemental Ca2+ provided an activity of 1 mM or more. Shoot Na+ concentrations either stayed constant from 50 to 150 mM external NaCl, or decreased in some genotypes at the higher salinity. Calculated rates of root...[Show more]
