Description

Gibberellin A4 CAS NO 468-44-0 is a specific, naturally occurring plant growth hormone belonging to the gibberellin family, a class of diterpenoid acids. This compound is valued for its targeted physiological activity in regulating plant development, including stem elongation, seed germination, and flowering. It is primarily utilized by professionals in the agricultural biotechnology, horticulture, and plant science research sectors to enhance crop performance and study plant physiology.

Application

• Agricultural Biotechnology: Used in research and development for modifying plant growth characteristics and improving crop yields.
• Horticulture: Application in promoting uniform flowering and fruit set in specific high-value crops under controlled conditions.
• Seed Technology: Employed to break seed dormancy and improve germination rates in certain plant species.
• Plant Physiology Research: Serves as a critical standard and reagent in laboratory studies to understand hormone signaling pathways.
• Malting Process: Potential use in the brewing industry to influence barley germination during the malting stage.
• Fruit Production: Can be used to manage fruit size and shape, and to induce seedless fruit development in some varieties.
