Results of regression analysis for (a) plant root-to-shoot ratio and (b) soil organic carbon in relation to soil available phosphorus. Dots represent the averages of bacterial treatments, with standard errors shown. The black line indicates the fitted regression line, with the regression coefficient (β) and standard error provided. Pots under the P-deficient condition were analyzed. Initial leaf length was included as a covariate in the model. * p < 0.05.
