Cold Stress Expression
Cold Stress Expression refers to phenotypic changes that occur in cannabis plants when exposed to low temperatures during growth or flowering. These environmental responses can include alterations in coloration (purples, blues, reds), terpene profiles, and resin production—traits breeders often deliberately select through generational work. Documentation of cold stress responses is valuable in breeding programs seeking to understand how genetic predisposition interacts with environmental triggers. Cold hardy cultivars and those showing distinctive pigmentation under cool conditions are frequently studied in both research and commercial breeding contexts. This classification is distinct from inherent anthocyanin expression; rather, it describes the plant's reaction mechanism to thermal stress.

Breeders working in cold climates or controlled environments use cold stress expression as a selection marker for environmental resilience. Understanding how a lineage responds to temperature fluctuations helps predict stability and phenotypic consistency across growing conditions.
