Secondary Metabolite Synthesis

Secondary metabolite synthesis refers to the biochemical pathways cannabis plants use to produce compounds beyond those required for basic growth and reproduction. These include cannabinoids (THC, CBD, CBG), terpenes, and flavonoids—traits shaped by both genetics and environmental conditions. Understanding these pathways is fundamental to breeding programs seeking to stabilize specific chemical profiles. Lineage records frequently report that certain parent plants reliably express higher concentrations of particular secondary metabolites, making them valuable breeding stock. The genetic basis for secondary metabolite production involves multiple genes and enzymatic cascades, making it a complex trait to select for across generations.

Breeders working in this category focus on isolating and stabilizing plant lines that consistently produce desired secondary metabolite ratios. Selecting parent plants with documented cannabinoid and terpene profiles, combined with environmental controls, helps create more predictable offspring phenotypes.
