Plant Defense Volatiles
Plant Defense Volatiles (PDVs) are secondary metabolites cannabis plants produce in response to environmental stress, herbivory, or pathogenic pressure. These compounds—including certain terpenes, phenolics, and sulfur-containing molecules—function as chemical signals that deter pests, attract beneficial insects, or communicate distress between plant tissues. In cannabis cultivation and breeding, PDV profiles are often observed alongside cultivar resilience traits, though the relationship between volatile composition and actual pest or disease resistance remains an active area of horticultural research. Lineage records frequently document PDV-rich phenotypes emerging from landraces adapted to challenging growing regions, suggesting selective breeding pressure toward stress tolerance.

Breeders working in organic and integrated pest management (IPM) systems monitor PDV expression as a potential marker for natural resilience traits. While PDVs themselves do not guarantee pest resistance, their presence may correlate with cultivars showing robust responses to environmental pressures, making them valuable indicators during selection for stable, low-input genetic lines.
