Table 2.
Mean values obtained from A/Ci curves at individual and combined sites. Data include: carboxylation efficiency (CE), relative stomatal limitation (I), carbon dioxide compensation point (CO2 CP), and Amax as maximum photosynthesis as measured at 1000 μmol·mol−1 [CO2] and saturating irradiance (μmol·m−2 s−1). Asterisks denote statistical significance between means (±SE) of red and green leaves (* p < 0.1, ** p < 0.05, *** p < 0.01).
