Fig.2
Photosynthetic parameters from five dominant common plant species (grasses and forbs) in the nutrient fertilization experiment fertilized with nitrogen (N), phosphorus (P) and both (NP). Panel (A), (B), (C) show response ratio of net photosynthetic rate (A) under N, P and both NP fertilization respectively. Panel (D), (E), (F) show response ratio of stomatal conductance (Gs) under N, P and both NP fertilization respectively. Panel (G), (H), (I) show response ratio of intercellular CO2 concentration (Ci) under N, P and both NP fertilization respectively. Panel (J), (K), (L) show response ratio of transpiration rate (Tr) under N, P and both NP fertilization respectively. Panel (M), (N), (O) show response ratio of water use efficiency (WUE) under N, P and both NP fertilization respectively. RR: response ratio
