Stress Pigmentation Response
Stress pigmentation response refers to the anthocyanin and carotenoid production that some cannabis plants exhibit when exposed to environmental stressors—typically cold temperatures, UV exposure, or nutrient imbalances during flowering. These pigments create visual shifts toward purple, red, blue, or orange hues in leaves and calyces. The trait is genetically heritable but phenotypically variable, meaning identical genetics may or may not express color depending on growing conditions. Breeders often distinguish between constitutive color (always present) and stress-induced color (environment-dependent), as the latter requires specific triggers to manifest reliably.

Breeders working with stress pigmentation response study parental lines to identify which genetics consistently produce anthocyanins under controlled environmental stress, enabling selection for more predictable color expression across cultivation environments. Understanding the genetic basis helps differentiate marketing-driven phenotypes from stable, heritable traits worth preserving in breeding
