| 2: Steady growth phase | ||||||
| ENF | 0.25 | 0.40 | 0.35 | Dynamic allocation coefficients regulated by the available light, water, and nitrogen (see Data and Methods). | ||

ENF: evergreen needleleaf forest; EBF: evergreen broadleaf forest; DNF: deciduous needleleaf forest; DBF: deciduous broadleaf forest; SHB: shrub; C3: C3 grass; C4: C4 grass; TDR: tundra; CROP: C3 crop. ENF, EBF, DNF, DBF, SHB, and TDR are woody biomes. C3, C4, and CROP are non-woody biomes. awoodFIX_p2 and arootFIX_p2 denote the fixed carbon allocation ratios to wood tissues and roots in the steady growth phase (phase 2). awoodRES_p2 and arootRES_p2 denote the resource limitation carbon allocation ratios to wood tissues and roots in the steady growth phase (phase 2).
