Temperature Stress Expression
Temperature stress expression refers to phenotypic changes that emerge when cannabis plants experience environmental heat or cold extremes during cultivation. These shifts—including altered leaf pigmentation, trichome density, resin composition, and growth patterns—occur without genetic mutation, representing the plant's physiological response to thermal pressure. Breeders and cultivators document these expressions to understand which genotypes maintain stability across climate ranges and which show dramatic plasticity. Temperature-induced traits are commonly associated with cannabinoid and terpene profile shifts, though the underlying mechanisms remain an active area of cultivation research. This category is distinct from cold-hardiness genetics, as it focuses on observable phenotypic drift rather than inherent resilience traits.

Breeders working in outdoor and variable-climate environments prioritize strains showing consistent expression across temperature swings. Understanding temperature stress expression helps identify which parent lines contribute genetic stability versus aesthetic or chemical responsiveness to thermal conditions.
