Promotes Tuber Formation and Enlargement: High-purity S-abscisic acid directly induces potato tuber formation, regulates nutrient allocation within the plant, and accelerates tuber expansion. This significantly increases individual tuber weight and overall yield, with potential yield gains of up to 30%.
Increases Starch Content: It enhances photosynthetic efficiency and accelerates the transport and accumulation of photosynthetic products in the tubers. This leads to a significant rise in starch content, improving the internal quality and storage stability of the tubers.
Strengthens Stress Resistance: It triggers the activation of the plant's own stress-resistance genes, boosting resilience against drought, low temperatures, waterlogging, salinity, and pests or diseases. It also mitigates adverse effects from chemical or fertilizer damage, ensuring normal growth and tuber development even under stressful conditions.
II. Key Application Guidelines for S-Abscisic Acid
Strictly control the application concentration; do not arbitrarily increase the dosage of high-purity formulations, as excessive concentrations can inhibit the normal growth of above-ground stems, leaves, and root systems.
It can be used in combination with fungicides (such as carbendazim) for seed potato soaking; this allows for simultaneous disinfection and germination promotion, achieving a synergistic effect of disease prevention and growth enhancement.
S-abscisic acid is light-sensitive; store it away from light and perform applications on cloudy days or in the evening to prevent strong light from degrading the active ingredients and compromising efficacy.
