Gibberellic Acid Treatment

Gibberellic acid (GA3) treatment is a plant hormone application technique used in cannabis breeding and cultivation to influence plant morphology and reproductive development. This naturally occurring gibberellin, derived from the fungus Gibberella fujikuroi, has been studied in cannabis research for its effects on stem elongation, flowering timing, and sex expression in dioecious plants. Breeders and researchers have documented that GA3 application can alter internode spacing, promote male flower development in genetically female plants, and modify overall plant architecture. The technique remains primarily a research and breeding tool rather than a standard cultivation practice, with applications varying significantly based on timing, concentration, and plant genetics. Understanding GA3's mechanisms helps breeders explore sex determination, phenotypic plasticity, and development in can

Breeders working with gibberellic acid treatment use it as a research tool to study sex determination, create male flowers on female plants for controlled breeding, and investigate how environmental and hormonal factors influence plant morphology. GA3 application has enabled exploration of sex-reversal techniques and phenotypic expression across different genetic backgrounds.
