Abbreviations: ANOVA, analysis of variance; CPPU, cytokinin-like compound forchlorfenuron; DM, dry matter.
Values are averages ±s.e. of the mean. n=5 for fresh weight, dry weight and DM; n=4 for starch concentration. P-values of significant main effects and interactions of fresh weight, dry weight, DM and starch concentration between treatments (untreated or CPPU-treated fruit) and carbohydrate supplies (standard and high) produced using a two-way ANOVA. Significant effects are highlighted in bold.
