FIGURE 1.

Colonized root length (left) and the extracted extraradical mycelia (ERM) dry matter of pots inoculated with Rhizoglomus irregulare for the intra- and inter-genotypic plant combinations containing either two wild type tomato plants (WT/WT), two resistant mutants (RMC/RMC) or one WT and one resistant mutant (WT/RMC). No colonization was observed in non-mycorrhizal pots. Means (±SE) are shown and values with the same letter are not significantly different (one way ANOVA, Tukey HSD, α = 0.05, n = 4).
