Fig. 5From: Testing allometric scaling relationships in plant rootsSMA 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 lineBack to article page
