Stress Induced Volatiles

Stress-induced volatiles (SIVs) are organic compounds that cannabis plants release in response to environmental or biological stressors—such as insect damage, pathogen pressure, nutrient deficiency, or extreme temperature fluctuations. These volatile organic compounds (VOCs) serve ecological functions in wild plants, including pest deterrence and plant-to-plant signaling. In cannabis breeding and cultivation, SIVs are of interest because their presence and composition can indicate plant health status and environmental response mechanisms. Breeders studying stress resilience often monitor volatile profiles as a marker of how cultivars handle adverse conditions. The aroma profile associated with stress-induced volatiles may shift noticeably during or after environmental pressure, distinguishing it from a plant's baseline terpene signature.

Breeders working on climate-resilient and pest-resistant cultivars track stress-volatile profiles to identify genetic markers of robust stress response. Monitoring SIV expression helps distinguish true environmental adaptation from merely superficial tolerance claims.
