Fig. 1. Genotypic response of flag leafA max to elevated CO2 (Y axis) as predicted with local sink-source ratio (LSSR, X axis) measured either under ambient CO2 level (A) or elevated CO2 (B). The termAmax700/Amax400 indicates the ratio of observations on plants grown at 700 vs. 400 µmol mol-1. For genotypes refer to Table 1. The 95% confidence interval is provided for the correlations and SEM error bars are provided for each genotype. Exp. 1, phytotron.
