Background: There is increasing concern about the fruit growth, development and quality of wax apple(Syzygium samarangense), a widely cultivated fruit tree in South East Asia. The growth and development of this fruit sometimes very low due low photosynthates supply and unfavourable growing conditions. Premature bud and fruit drop is a serious problem in wax apple production and quality. Growth regulators, hydrogen peroxide and phloemic stress are important tools to improve the quality and reduced the preharvest fruit dropof wax apple. Objectives:To investigate the causes and remedies of premature fruit drop of wax apple and the findings of this study will help to increase the fruit yield by reducing the bud and premature fruit abscission.Results:It was observed that plant growth regulators, hydrogen peroxide and phloemic stress improved the fruit retention and improved the quality of fruits.GA3 50 and 20 mg/L treatment during flowering reduced the bud and fruit drop of wax apple.Synthetic auxin (2,4-D and NAA) at 5 mg/L treatment during the flowering also reduced the fruit drop and enhanced the quality. C and V-shaped girdling 3 weeks before flowering increased number of flowers and reduced the premature fruit drop of wax apple fruits. Conclusion: This review also concluded that hydrogen peroxide treatment at flowering and fruit formation stage reduced bud and fruit drop and improve the fruit qualtiy of wax apple. The findings of the review have significant effect to reduce preharvest fruit drop and develop wax apple fruit industries in tropical climates.
