Secondary Metabolism Traits

Secondary metabolism refers to the biochemical pathways in cannabis that produce non-essential compounds like cannabinoids, terpenes, and flavonoids. Unlike primary metabolism (photosynthesis, growth), secondary metabolism generates the specialized molecules that define strain character and phenotype variation. These traits are heavily influenced by genetics, environment, and maturation timing, making them central to breeding programs and cultivar selection. Research into secondary metabolism has revealed that cannabinoid and terpene production varies substantially across lineages, with some families consistently expressing elevated levels of specific compounds. Understanding secondary metabolism is foundational for breeders seeking to stabilize or enhance particular chemical profiles in their work.

Breeders leverage secondary metabolism traits to target desired cannabinoid ratios, terpene blends, and flavor compounds in offspring. Selective breeding for high expression of specific terpenes or cannabinoid types relies on identifying and crossing plants with robust secondary pathways.
