Temperature Triggered Pigmentation
Temperature triggered pigmentation refers to anthocyanin and carotenoid expression in cannabis plants that intensifies under cooler growing conditions, typically during flowering or late vegetative stages. This phenotypic trait causes leaves, bracts, and sometimes entire plants to display purple, red, blue, or orange hues when nighttime temperatures drop below species-optimal ranges. The mechanism is distinct from genetic predisposition for color; rather, environmental stress triggers pigment accumulation as a protective response. Many cannabis lineages carry the genetic capacity for this trait, though expression varies based on cultivar, timing, and temperature differential. Documentation in breeding records frequently distinguishes between true genetic color stability and temperature-dependent coloration, as the latter may not reliably produce colored offspring in warmer climates.

Breeders working in cooler regions or using controlled environments often select parents showing pronounced temperature-responsive pigmentation to stabilize this trait across generations. Understanding whether coloration is genetically fixed or environmentally triggered informs decisions about germplasm preservation and trait stacking in breeding programs.
