Significance (GS)
Significance (T)
Different letters indicate significant differences between genotype means with values obtained from one-way ANOVA; values for comparison of treatment means were obtained from a two-way ANOVA involving salt treatment and genotype; dm: dry mass; GC: genotype control; GS: genotype salt; se: standard error. values describing significant effects of genotype (G) for each of C and S and significant effects of treatment (T) are included.
