Heat Stress Responses
Heat stress responses refer to observable plant adaptations and phenotypic expressions that occur when cannabis plants experience elevated temperatures above their optimal growth range. Breeders and cultivators monitor these traits to identify genotypes with natural resilience or sensitivity to thermal stress. Common responses include leaf curling, stomatal closure, reduced internodal spacing, and altered trichome production. Understanding heat stress phenotypes helps breeders select for cultivars suited to warm climates or breeding programs focused on environmental stability. Some lineages show genetic predisposition toward heat tolerance, while others demonstrate clear sensitivity markers used in selective breeding.

Breeders working in arid or warm regions prioritize heat stress response traits to develop stable cultivars. Identifying plants that maintain vigor, cannabinoid expression, and terpene stability under thermal stress informs long-term breeding goals for climate adaptation.
