Physiological Responses of Wild and Cultivated Barley to the Interactive Effect of Salinity and Iron Deficiency

Table 4

Fe concentrations (μmol Fe·g−1 DW) in shoots and roots of H. maritimum and H. vulgare plants hydroponically grown under iron supply (+Fe) or iron starvation (−Fe) at different salt levels (0, 100, 200, 300 mM) over 60 h. Means of three replicates. For each line, means followed by the same letters are not significantly different at 5% according to Duncan’s test.
