High concentrations of NATURAL gibberellins are associated with the juvenile phases of citrus development. GA3, the most commercial used forum of the hormone, has shown stimulation of budbreak and vegetative shoot growth, but inhibits the transition from vegetative to reproductive flowering growth in citrus if applied prior to irreversible commitment to flowering, but it does not affect flowering when applied after irreversible commitment to floral development. GA3 also prevents senescence in citrus and can maintain chloroplast thus keeping citrus fruit green longer. Lastly, GA3 is sprayed prior to harvest time to delay rind senescence so that treated fruit remain physiologically young for a longer period of time, improving on tree storage and extending harvest.
