The study was conducted to evaluate the effect of CPPU on the growth and fruit quality development of water apple fruits (Syzygium samarangense). Three concentrations of CPPU at 10, 15, 20 mg/l and water control were applied using swabbing technique. The number of buds and fruit setting were increased at 15 mg/l CPPU concentration as compared to the other concentrations (10 and 20mg/l). The premature fruit dropping was decreased. It was observed that the application of CPPU at 15mg/l increased fruit length and diameter. In addition to that fruit growth, maturity development and per fruit weight were higher at CPPU at 15mg/l compared to other concentrations and water control. With regard to fruit quality, the application of CPPU at 15mg/l increased TSS and pH content in the fruit compared to the other concentrations (10 and 20mg/l) and water control. From this study it can be seemed that 15mg/l CPPU was showed better results than other concentrations (10 and 20mg/l) and water control.
