Gibberellic Acid (GA3) is mainly used for sprouting in potato cultivation. It breaks the dormancy of seed potatoes, promotes sprouting, and increases emergence rate and seedling growth speed. Its specific effects are as follows:
Gibberellic Acid Sprouting Effect
Gibberellic Acid, by regulating the balance of plant hormones, can quickly break the dormancy state of potato seed potatoes, causing tubers or cut pieces to sprout rapidly. It is suitable for sprouting cut seed potatoes, ensuring uniform emergence and vigorous seedlings.
Gibberellic Acid Usage Precautions
Concentration Control: The solution must be prepared strictly according to the ratio when soaking seed potatoes. The concentration differs significantly between whole potatoes and cut pieces. Excessive concentration or prolonged soaking time will result in weak seedlings, affecting yield.
Environmental Management: After cutting, place in a cool, shaded place to allow the cut surfaces to heal. Avoid direct sunlight, which can cause excessive evaporation or mold growth.
Rain Protection: Outdoor sprouting requires rain protection. Rainwater soaking can easily cause rot and affect sprouting.
