Thermal Dimorphism
Thermal dimorphism in cannabis refers to observable phenotypic differences that emerge in response to temperature fluctuations during the plant's growth cycle. Plants exhibiting this trait commonly show distinct variations in leaf morphology, pigmentation, internode spacing, or flowering timing when grown under cooler versus warmer conditions. Breeders working in temperate and highland regions have long noted these responsive traits, as they influence crop timing and final plant structure. Temperature-sensitive genotypes can display darker foliage, tighter node spacing, or accelerated maturation in cooler environments—traits often linked to landrace populations from varied elevates. Understanding thermal dimorphism helps breeders select for climate resilience and predictable growth patterns across seasonal variation.

Breeders leverage thermal dimorphic traits to develop cultivars suited to specific growing seasons and geographical zones. Selecting parents that exhibit controlled, measurable responses to temperature enables more stable F1 hybrids for outdoor cultivation across diverse climates.
