A Whole Plant Analysis of Chloride and Sodium Exclusion Using a Range of Grapevine Rootstock Genotypes

Figure 1

Root (), petiole (), and stem () Cl⁻ concentration of all salt-treated genotypes plotted against the lamina Cl⁻ concentration. Regression analysis of the salt-treated vines shows significant correlations between the Cl⁻ concentration in the laminae and that in the petioles (,  = 0.97, slope = 1.79) and between the Cl⁻ concentration in the laminae and that in the stem (,  = 0.87, slope = 0.19) but not between the Cl⁻ concentration in the laminae and that in the roots ().
