GA3 is widely used in agriculture to promote plant growth and improve crop yields. It stimulates seed germination, particularly in seeds that require specific conditions to sprout. GA3 is also applied to enhance fruit size and quality, especially in grapes, apples, and citrus fruits. In horticulture, it is used to induce flowering in plants that may not bloom under normal conditions. Additionally, GA3 helps in breaking dormancy in tubers and bulbs, ensuring uniform growth. It is also utilized in the brewing industry to accelerate the malting process in barley. Overall, GA3 plays a crucial role in optimizing plant development and agricultural productivity.
