Best linear unbiased estimates for leaf Na+and Cl- concentrations (mg kg-1 DW) in 20 bread wheat entries (Triticum aestivum L.), three durum wheat entries (Triticum turgidum subsp durum cv. Tamaroi, Tamaroi-Nax2, and Yawa), and one barley cultivar (Hordeum vulgare L.cv. Clipper) under control, salinity (100 mM NaCl), and sodicity (8 g kg-1 Na+-humate) in Experiment 3 (n = 4).
