Gibberellic Acid: Increase Fruit Size and Yield, Reduce Drop

Resumen

This article discusses the use of gibberellic acid (GA), the naturally occurring plant hormone, on huanglongbing (HLB)-affected trees. The results were generated from a 3-year trial in which Valencia trees were treated with GA in the fall. The outcomes suggest that GA can be effectively used for synchronizing and suppressing profuse flowering without negatively affecting yield in Valencia. In addition, GA treatment has potential to improve yield and fruit size while reducing fruit drop.
