FIGURE 5.

Substrate hydraulic conductivity (K) at three different levels of substrate water potential (pF) of non-mycorrhizal (black columns) pots and of pots inoculated with R. irregulare (white columns) 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). Means (n = 4; ±SE) are shown, deriving from individual pot specific fits. Asterisks denote significant differences between non-mycorrhizal and mycorrhizal pots. Significant differences between planting combinations or factor interaction were not detected (two way ANOVA, α = 0.05, ^nsP > 0.05, ^∗P < 0.05).
