Gibberellic Acid GA3 Powder For Agriculture

Gibberellic Acid GA3 Powder for Agriculture

Brief Introduction

Gibberellic Acid (GA3) is a naturally occurring plant hormone belonging to the gibberellin family. It plays a critical role in regulating various physiological processes, including seed germination, stem elongation, flowering, and fruit development. As one of the most widely used and biologically active gibberellins, GA3 is extensively applied in agriculture, horticulture, and research to enhance crop yield, improve fruit quality, and break seed dormancy. This high-purity formulation is designed for reliability and effectiveness in both laboratory and field applications.

Detailed Description

Gibberellic Acid (GA3) is a tetracyclic diterpenoid compound synthesized by the fungus Gibberella fujikuroi. It is recognized for its potent growth-promoting properties and ability to modulate plant development at low concentrations. GA3 works by stimulating cell division and elongation, influencing gene expression, and interacting with other plant hormones. Its versatility makes it a valuable tool for optimizing plant performance under various environmental conditions.
