Growth Regulators for Yield and Quality Enhancement in Litchi (Litchi chinensis L) - A Review

The existing gaps in yield potential, production of poor quality, un-attractive fruits and negligible export potential of quality litchi fruit are the main concerns. These need to be combated in modern day fruit production to meet the ever increasing demand to nourish the growing population and increasing the economic returns. Plant growth hormones play important role in the integrated developmental activities of the fruits, yield as well as quality. Exogenous application of plant bio regulators in small quantities has become an important component for inhibiting or modifying the physiological processes by replacing or supplementing the endogenous hormones when their levels are below than required to bring a positive change in the course of plant development, thereby regulating different aspects such as fruit drop, quality and yield. Keeping all these factors in consideration, the present literature has been reviewed to clear the concepts and approaches involved with the use of different PGRs in relation to litchi fruit growth, development, yield, quality, shelf life etc. International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 6 Number 8 (2017) pp. 2152-2159 Journal homepage: http://www.ijcmas.com
