Uv Stress Pigmentation
UV stress pigmentation refers to anthocyanin and other secondary metabolite accumulation triggered by ultraviolet light exposure during cannabis cultivation. Plants develop purple, red, or blue coloration in leaves, bracts, and sometimes flowers as a photoprotective response to UV-B radiation. This trait is genetically variable across cultivars—some lineages express strong pigmentation under UV stress while others remain green. Breeders studying this phenomenon often work with controlled UV lighting to identify and select for photostability markers. The mechanism involves flavonoid biosynthesis pathways common to many plant families, making UV-stress pigmentation an area of active horticultural and genetic research.

Breeders use UV stress tests to evaluate genetic resilience and select parent plants with consistent photoprotective responses. Understanding pigmentation triggers helps optimize light spectrum management in controlled environments while identifying stable traits for line stabilization.
