Wound Response

Wound response refers to volatile organic compounds (VOCs) and secondary metabolites that cannabis plants produce in reaction to physical damage, pest pressure, or environmental stress. These chemical signals are part of the plant's defensive biochemistry and include various terpenes and terpenoids that increase following mechanical injury or herbivory. Breeders and researchers study wound response patterns to understand plant resilience, stress tolerance, and the relationship between environmental triggers and terpene expression. The compounds released during wound response are distinct from the plant's baseline volatile profile and reflect dynamic biochemical processes rather than static genetic traits. This phenotypic expression varies across cultivars and growing conditions, making wound response a useful marker for studying plant vigor and secondary metabolism.

Breeders working with stress tolerance and resilience traits monitor wound response as an indicator of plant vigor and defense mechanisms. Understanding how cultivars activate their chemical defense systems helps inform selection for plants with robust responses to environmental challenges.
