SMA results of the relationship between plant fine root productivity (P) and biomass (M) for plants with different leaf phenology and phylogeny. Values are log-transformed (base 10). The lines show the fitted regression equations for deciduous species: log10P = − 0.135 + 0.98 × log10M (95% C.I. for slope is 0.92 to 1.05, r2 = 0.63, n = 333); evergreen species: log10P = − 0.011 + 1.01 × log10M (95% C.I. for slope is 0.94 to 1.08, r2 = 0.38, n = 493); angiosperm species: log10P = − 0.136 + 1.02 × log10M (95% C.I. for slope is 0.96 to 1.08, r2 = 0.56, n = 497); gymnosperm species: log10P = 0.046 + 0.97 × log10M (95% C.I. for slope is 0.89 to 1.05, r2 = 0.42, n = 329). The short dash lines refer to the 95% confidence intervals. The pink line refers to the 1:1 line
