GA3, Gibberellic Acid is a natural plant hormone. I said tGA3 can help jujubes to set fruits last time. One of my friends in NJ tried GA3 on his seven years old’ jujube plant and he got fruits for the first time last year. I find GA3 can also be used to grapes to increase the size of fruits and help some unnatural seedless grape to become seedless. Reliance is a very good grape varieties, but fruits are too small. You can apply GA3 to reliance. Dip the reliance grape in 45mg/kg solutions when the fruits are pea-size.
