Desiccation Tolerance

Desiccation tolerance is not a terpene, but rather a physiological trait describing a plant's ability to survive extended periods of low moisture availability without permanent damage to cellular structure. In cannabis breeding, this characteristic is studied as a stress-response mechanism that affects terpene volatile retention and cannabinoid stability during storage and cure cycles. Breeders working with landrace genetics—particularly those from arid regions like Hindu Kush or Moroccan cultivars—often observe desiccation-tolerant phenotypes. This trait influences post-harvest terpene preservation; plants exhibiting robust desiccation tolerance may retain aromatic compounds more effectively during prolonged dry conditions, though excessive water loss during curing can still degrade volatile profiles.

Breeders select for desiccation tolerance to improve resilience in cultivation environments with variable humidity and to enhance post-harvest stability during extended storage. Understanding this trait supports optimization of cure parameters and long-term seed viability preservation.
