Secondary Metabolite Induction

Secondary metabolite induction refers to the plant's biochemical response to stress conditions—environmental or pathogenic—that triggers production of defensive compounds beyond primary metabolism. In cannabis breeding contexts, researchers and cultivators observe that controlled stress (light intensity, nutrient ratios, temperature fluctuation, pest pressure) can upregulate terpene and cannabinoid synthesis. This phenomenon is documented across many plant families and is increasingly studied in cannabis genetics to understand how genetic background interacts with environmental triggers. Lineage records frequently report that certain cultivars show pronounced metabolite expansion under specific stress conditions, though the mechanism varies by genotype and growing method.

Breeders working in this category select parent plants that demonstrate robust secondary metabolite production under mild stress, aiming to stabilize or amplify terpene and cannabinoid profiles in offspring. Understanding secondary metabolite induction helps distinguish between inherent genetic potential and expression that depends critically on cultivation environment.
