Effects of mineral fertilizer supply (low, high) and soil organic matter (SOM) content (low, high) on C:N ratio of <i>Triticum aestivum</i> leaves in unsterilized soil.

<p>a) C:N ratio explained by mineral fertilizer supply. b) C:N ratio explained by SOM content. Error bars represent standard errors. Significant differences are indicated by different letters (Tukey Honest Significant Difference contrast test).</p

Effects of soil sterilization and <i>Rhizoctonia solani</i> addition on aboveground plant biomass of and fresh aphid biomass.

<p>a) Effects on aboveground plant biomass of <i>Triticum aestivum</i>. b) Effects on fresh aphid biomass of <i>Sitobion avenae</i>. Error bars represent standard errors. Significant differences are indicated by different letters (Tukey Honest Significant Difference contrast test).</p

ANOVA models explaining fresh aphid biomass (<i>Sitobion avenae</i>, √(ln+1) transformed), aboveground dried plant biomass (stem and flower biomass) of wheat (<i>Triticum aestivum</i>) and plant C:N ratio (√ transformed) by soil organic matter (SOM) content, fertilizer supply, <i>Rhizoctonia solani</i> addition and all possible interactions.

<p>All analyses were done on unsterilized soil. Significant (P<0.05) effects are highlighted in bold, N = 104.</p

Effects of soil organic matter (SOM) content (low, high) and mineral fertilizer supply (low, high) on plant- and aphid biomass on unsterilized soil.

<p>a) Plant biomass of <i>Triticum aestivum</i>. b) Aphid biomass of <i>Sitobion avenae</i>. Error bars represent standard errors. Significant differences are indicated by different letters (Tukey Honest Significant Difference contrast test).</p

Effects of <i>Rhizoctonia solani</i> addition on plant- and aphid biomass under different soil conditions on unsterilized soil.

<p>a) Aboveground plant biomass of <i>Triticum aestivum</i> explained by <i>R</i>. <i>solani</i> addition and mineral fertilizer supply (low, high). b) Aphid biomass of <i>Sitobion avenae</i> explained by <i>R</i>. <i>solani</i> addition and soil organic matter (SOM) content (low, high). Error bars represent standard errors. Significant differences are indicated by different letters (Tukey Honest Significant Difference contrast test).</p
