Adding plant hormones?
« on: August 30, 2018, 01:07:29 AM »
Hi, I've been looking into effect of gibberellic acid and found an old post from Millet mentioning higher yield. Yet I have more questions. An article I had been reading mentioned that during winter, naturally occurring levels of gibberellic acid along with nitrogen drops and affects the quality of the fruit. If one were to supplement that through foliar feeding or other means would this be something that would not take?

I don't advise you to apply. It will make the inter node growth long and weak during strong winds.

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.
