Substrate hydraulic conductivity (K) as a function of the volumetric water content (Θ) of non-mycorrhizal (black line) pots and of pots inoculated with R. irregulare (red line) for intra- (WT/WT; RMC/RMC) and inter-genotypic (WT/RMC) plant combinations. Means (n = 4; ±SE) are shown, deriving from individual pot specific fits. There was a significant mycorrhizal effect at K6kPa (P = 0.040) and Θ10kPa (P = 0.034). Marginal significances were observed for Θ3kPa (P = 0.072) and Θ100kPa (P = 0.067). Significant differences between planting combinations or factor interaction were not detected (two way ANOVA, α = 0.05, n = 4).
