Fig. 1

Ion leakage expressed as percentage in plants exposed to 0, 50, 100 or 200 mM NaCl. Data are shown as mean with at least 5 independent biological replicates and error bars indicate standard error. Two-way ANOVA were carried out and comparison among means values were separated using the Bonferroni multiple comparison test (P < 0.05). Significant differences are indicated by asterisks (* P < 0.05, ** P < 0.01, *** P < 0.001) of ion leakage (%) after different saline irrigation in cv “Porto” (A) vs cv “Sunny wind” (B)
