The most important function of Gibberellic acid (GA3) in pineapple is to promote flowering.It's can combine with foliar fertilizer to spray during the flowering period, promote flowering effect is significant.

Strawberry flower bud differentiation and fertilization management are very important to improve yield and quality.Commonly used chemicals include Gibberellic Acid (GA3), Brassinolide (BR) and Difenoconazole.

Gibberellic Acid GA3,strawberries can promote the formation of flower buds under low temperature and short daylight conditions.However, when strawberries are cultivated under protective facilities, or because the temperature during planting is too high and cannot meet the normal low temperature requirements, the plant growth will be dwarfed and the flower buds will differentiate,Reduced flowering and fruiting.

Cytokinin
Spraying with 10~20mg/L liquid after the flowers fall can increase the leaf color, thicken the leaves, increase the fruit setting rate by 22.4%, increase the single fruit weight by 13.2%, reduce the weight of the peach stone, increase the rate of large fruit, mature 4 days earlier, and improve Coloring, improving quality. The total sugar content increase by 0.6, the soluble solids increase by 1%, and the fruit acid decrease.
