There are many problems during the continuous flowering and fruit setting period of strawberries, such as less flowering, low fruit setting rate, slow fruit enlargement, small fruit size, poor fruit coloring, and poor taste. The scientific application of plant growth regulator can effectively solve these problems, thereby promoting plant growth and development, promoting flower and fruit preservation, and improving the economic benefits of strawberries.

The most prominent function of Gibberellic acid (GA3) is to accelerate the growth of cells and increase the auxin content in plants. 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.
