| Product Name | Gibberellic Acid (GA3) |
| Catalog No. | RESK-0596 |
| Description | Gibberellic acid, also known as gibberellin A3 (GA3), is an endogenous plant growth regulator that plays various important roles in plant development: 1) it stimulates cell division and elongation, thereby promoting rapid stem and root extension; 2) for some plants whose seeds require stratification or light-induced germination, gibberellic acid can break dormancy and induce the initiation of mitosis and germination; 3) it improves the seed germination rate. It also participates in physiological activities such as gravitropism, tension, and flowering patterns. Low concentrations of GA3 can regulate plant growth very significantly; the commonly used working concentration is 0.01-5 mg/L. High concentrations of GA3 may produce opposite effects. This product is suitable for plant cell culture. It can first be dissolved in ethanol (50 mg/mL) and then diluted with water to the required working concentration; fresh preparation before use is recommended. Alternatively, after filter sterilization, it can be stored as a relatively concentrated stock solution (diluted aqueous solution) at 4 °C protected from light. |
| Intended Use | Used as a plant growth regulator in plant cell culture. |
