Plant growth regulators for tropical fruits

Abstract

With the notable exception of 2,4-D/GA treatments of diverse citrus crops, where improved fruit set, reduced fruit drop and the ability to delay harvesting without loss of fruit quality are recognized benefits, few applications have been developed for the use of auxins in tropical fruits. Recent work has shown that GA will delay post-harvest ripening and improve the quality of bananas, and NAA treatment of oil palm to delay fruit abscission has increased yield and oil content.
