Figure 4.

K⁺ contents of root and shoot tissues of Serendipita indica infected and noninfected control plants. The plants were grown in modified Hoagland medium under K⁺ starvation (0 mM KCl) (a) or at 1 mM KCl (b). The box plots show the median, quartiles and extremes of the compared data sets (n= 15). Different letters indicate significant differences between the compared conditions and genotypes analysed by ANOVA and a Tukey−Kramer post hoc test (p < 0.05).
