Significance (GS)
Different letters indicate significant differences between genotype means with values obtained from one-way ANOVA; control and salt treatment means are compared using standard errors; dm: dry mass; GC: genotype control; GS: genotype salt; se: standard error. For each treatment, values for significant genotype (G) effects are included.
