Heat Stress Response
Heat stress response refers to a plant's physiological and morphological adaptations when exposed to elevated temperatures during growth. Cannabis populations demonstrate variable tolerance levels, influenced by both genetics and environment, with some lineages historically selected from warmer climates showing greater resilience. Breeders working in arid or hot regions often prioritize heat tolerance as a functional trait, observing differences in leaf structure, water retention, and flowering timing across cultivars. Understanding heat response is relevant for cultivation planning, particularly in outdoor or greenhouse settings where temperature fluctuations occur. Documentation of heat tolerance typically focuses on observable traits like leaf margins, stomatal density, and growth rate rather than molecular markers.

Breeders selecting for heat-adapted genetics often cross landraces or cultivars from warm regions with established cultivars to introduce tolerance traits. Heat stress response data informs cultivation recommendations and helps develop lines suited to specific climatic zones or season extensions.
