Description

Gibberellin A9 Methyl Ester is a specific, biologically active methyl ester derivative of the plant hormone gibberellin A9. This compound is valued for its role as a potent plant growth regulator, influencing processes such as stem elongation, seed germination, and fruit development. It is primarily utilized by researchers in agricultural science, plant physiology, and by manufacturers formulating advanced plant growth stimulants and bioregulators for high-value crops.

Application

• Plant Physiology Research: A key standard and tool for studying gibberellin signaling pathways, receptor interactions, and metabolic fate in plants.
• Agricultural Biotechnology: Used in laboratory studies to develop and test new plant varieties with modified growth characteristics, such as dwarfism or controlled flowering.
• Seed Treatment Formulations: Incorporated into specialized seed coatings or priming solutions to enhance and synchronize germination rates, particularly for seeds with dormancy issues.
• Horticulture and Floriculture: Applied in controlled environments to manage plant height, promote bolting in long-day plants, or improve fruit set and development.
• Reference Standard: Serves as a high-purity analytical standard for the quality control and quantification of gibberellins in commercial products or plant tissue samples via HPLC or GC-MS.
• Synthetic Intermediate: Used in organic synthesis for the preparation of other gibberellin analogs or labeled compounds for tracer studies.
