Stress Induced Terpene Shifts

Stress-induced terpene shifts refer to changes in volatile compound profiles that occur when cannabis plants experience environmental stressors such as heat, drought, pest pressure, or mechanical damage. Research in plant secondary metabolism suggests that terpene ratios and concentrations can fluctuate in response to these conditions, though the magnitude and direction of these shifts vary by genotype and stressor type. This phenomenon is of particular interest to breeders and cultivators seeking to understand how growing conditions influence final chemotype expression. Terpene volatilization under stress may represent a plant defense mechanism, though detailed mechanisms remain incompletely characterized in cannabis specifically.

Breeders working in stress-resilience selection often monitor terpene profiles across different environmental conditions to identify stable genotypes. Understanding which lineages maintain consistent terpene expression under adversity versus those showing significant profile drift helps inform crop planning and phenotype stability claims.
