Product Overview
1-Naphthylacetic Acid (NAA), CAS No. 86-87-3, is a highly effective and versatile synthetic plant growth regulator with auxin-like activity. Appearing as a white crystalline powder, it boasts a purity of 99.0% min. and a precise melting point of 130-134°C. This premium-grade regulator is engineered to mimic the physiological functions of endogenous auxin (IAA), offering robust control over various growth processes in a wide range of crops. It is soluble in common organic solvents like acetone, ether, and chloroform, as well as in alkaline solutions, ensuring ease of formulation and application.
Key Features & Advantages
- Broad-Spectrum Efficacy: Suitable for a vast array of crops including fruits, vegetables, cereals, and cotton.
- Multi-Functional Action: Promotes root development, prevents flower and fruit drop, improves fruit set, induces seedless fruit formation, and can inhibit growth at higher concentrations for specific purposes.
- Yield & Quality Booster: Enhances cell division/expansion, photosynthesis, and overall plant metabolism, directly contributing to increased yield and improved crop quality.
- High Purity & Stability: With 99%+ purity and strict control on residue on ignition (0.1% max) and loss on drying (0.5% max), ensuring reliable and consistent performance.
- Technical Synergy: Can be effectively combined with IAA or other rooting agents for superior results in root promotion and overall plant vigor.
Primary Applications & Usage Guidelines
- Rooting Agent: Significantly promotes the rooting of cuttings. For optimal results (balanced root growth and seedling vitality), combination with IAA or other rooting agents is recommended.
- Fruit Set & Retention: Effectively increases fruit setting rate and prevents pre-harvest drop of fruits (e.g., in orchards) and bolls (e.g., in cotton). Caution: Concentration must be carefully controlled to avoid opposite effects (ethylene induction) at excessively high levels.
- Seed Treatment: Soaking seeds of rice or wheat in NAA solution can stimulate germination and enhance final yield.
- Growth Regulation: Alters male/female flower ratios and, at elevated concentrations, manages excessive vegetative growth.
- Application Method: For foliar spray on melons and fruits, ensure uniform coverage on leaves for best absorption.
Packaging & Storage
- Standard Packaging: 1 kg/aluminum bag, 25 kg net/fiber drum. Customized packaging is available upon request to meet specific logistical or handling needs.
- Storage Conditions: Store in a cool, dry, and well-ventilated place within tightly sealed containers. Protect from heat sources to prevent decomposition.
