Phenotypic diversity in twenty Arabidopsis genotypes grown at 200 µmol m⁻² s⁻¹ light intensity (a, c, e, g), and 550 µmol m⁻² s⁻¹ light intensity (b, d, f, h). Graphs (a, b) shows Φ_PSII through time; c, d shows chlorophyll reflectance index; e, f shows projected leaf area (PLA). Finally, g, h shows percentage change in PLA every 3 h. All data points are genotypic means (BLUEs), combining observations on replicates from different experiments into one representative value for each genotype at each time point. Six genotypes, An-2 (yellow circles), BC354 (purple circles), Bur-0 (green squares), Col-0 (black triangles), Ely (red circles) and Ts-1 (blue squares) are indicated in colour. Error bars have been excluded for clarity, the significance of between genotype differences is apparent from the heritability estimates in Fig. 6
