Fig. 3. Relationships of (a) leaf assimilation rate measured at 2000 µmol m^-2 s^-1 (C_Amax) and (b) leaf CO₂ assimilation rate measured in the dark (C_Adark) plotted against specific leaf nitrogen (SLN) of individual leaves. These responses are derived from data of Exp. P2 (2000-2001) specifically used to measure the response of leaf assimilation rate to light intensity.
