Figure 6From: Evaluating contribution of ionic, osmotic and oxidative stress components towards salinity tolerance in barleyHydroxyl radical-induced changes in net K+flux measured from the elongation (A) and mature (B) root zones of three barley cultivars. The hydroxyl radical-generated copper ascorbate mix (0.3 mM CuCl2 and 1 mM Na+-Ascorbate) was added at the time indicated by an arrow. Mean ± SE (n = 6-8). The sign convention is “efflux negative”.Back to article page
