1. Product Overview
S-ABA (S-Abscisic Acid) is a naturally occurring plant hormone widely present in all green plants. It is a high-purity and high-biological-activity plant growth substance produced through advanced microbial fermentation technology.
It is non-toxic, non-irritating, and environmentally friendly, making it a safe and sustainable solution for modern agriculture. As a new-generation natural bio-active compound, S-ABA plays a crucial role in regulating plant growth, development, and stress responses.
2. Biological Function and Mode of Action
S-ABA is one of the most important phytohormones involved in plant physiological regulation. It functions mainly by:
- Integrating multiple environmental stress signals
- Regulating downstream stress-response pathways
- Balancing plant growth and reproductive development
Through precise physiological regulation, it helps plants adapt to adverse conditions while maintaining yield and quality.
3. Key Agronomic Benefits of S-ABA
3.1 Fruit Ripening and Quality Enhancement
S-ABA significantly promotes fruit ripening and coloration, especially in grapes and berry crops. It increases:
- Reducing sugar content
- Soluble solids (Brix)
- Uniform coloration and market appearance
This allows fruits to reach market standards earlier with improved commercial value.
3.2 Yield and Dry Matter Accumulation
During the filling stage of major crops such as rice, wheat, and corn, S-ABA enhances dry matter accumulation, contributing to:
- Improved grain quality
- Higher thousand-grain weight
- More stable yield performance
3.3 Root Development and Vegetative Growth
Applied at early growth stages, S-ABA:
- Promotes root initiation and elongation
- Improves nutrient and water uptake
- Enhances seedling vigor and transplant survival
3.4 Stress Resistance and Growth Balance
S-ABA helps crops cope with environmental stresses such as drought, temperature fluctuations, and nutrient imbalance. When used in combination with fertilizers, it improves nutrient absorption efficiency and overall crop resilience.
3.5 Compatibility with Other Plant Growth Regulators
When properly formulated, S-ABA can be combined with other plant growth regulators to:
- Correct abnormal fruit growth
- Reduce deformity, cavity formation, and fruit cracking
- Improve overall fruit uniformity
