For phytochemical analysis, 15–20 fruit samples of each genotype were randomly collected at each time point from 14 to 125 DAFB in 2011. In 2012, the exogenous CA application was conducted at 30 DAFB, and then 20 fruits of each treatment were sampled weekly before spraying and in the following four weeks.All fruits were transported rapidly to the lab as soon as possible.
