Drought Adaptation

Drought adaptation refers to physiological and morphological traits that enable cannabis plants to maintain function under water-stressed conditions. These traits include waxy leaf coatings, reduced leaf surface area, and efficient root systems that help minimize water loss while maintaining photosynthetic capacity. Lineage records frequently report drought tolerance in landraces originating from arid regions—particularly Afghan, Moroccan, and certain South Asian cultivars. This is not a volatile terpene but rather a plant phenotype influenced by genetic factors and environmental pressure. Understanding drought adaptation is relevant to breeders working in water-limited climates or seeking resilience traits for breeding programs.

Breeders select for drought tolerance to develop cultivars suited to semi-arid cultivation and to reduce irrigation demands in commercial settings. Crossing drought-adapted landraces with modern cultivars requires careful assessment of morphology, root structure, and leaf characteristics to balance stress resilience with yield potential.
