Metabolite profiles. Changes in the metabolite concentrations (mg g FW -1) during fruit development for 106 genotypes. a) Glucose, b) Fructose, c) Sucrose and d) Sorbitol concentrations. The symbols represent the mean of the two technical replicates, open triangles represent the ‘low-fructose-to-glucose-ratio’ genotypes, and closed circles represent the ‘standard-fructose-to-glucose-ratio’ genotypes. The lines are fitted linear models by GLMM for all of the ‘low-fructose-to-glucose-ratio’ genotypes (red dashed line) and for all of the ‘standard-fructose-to-glucose-ratio’ genotypes (blue solid line).
