Hexose phosphate profiles. Changes in the hexose phosphates concentration (mg g FW -1) during fruit development for ten genotypes. a) G1P (glucose-1-phosphate), b) G6P (glucose-6-phosphate) and c) F6P (fructose-6-phosphate) concentrations. The symbols represent the mean of the three biological and the two technical replicates, open triangles represent the ‘low-fructose-to-glucose-ratio’ genotypes and closed circles the ‘standard-fructose-to-glucose-ratio’ genotypes. The segments represent the standard error on biological replicates. The lines are fitted linear models by GLMM for all of the five ‘low-fructose-to-glucose-ratio’ genotypes (red dashed line) and for all of the five ‘standard-fructose-to-glucose-ratio’ genotypes (blue solid line).
