Plant Secondary Metabolites

Plant secondary metabolites are organic compounds produced by cannabis plants beyond primary growth and reproduction needs. These include terpenes, flavonoids, cannabinoids, and phenolic compounds that accumulate in trichomes and leaf tissue. Secondary metabolites often develop in response to environmental stress, genetics, and cultivation conditions, contributing to the plant's chemical profile. In cannabis breeding and genetics documentation, secondary metabolite profiles serve as markers for strain identification and lineage tracking. Breeders frequently select parent plants based on their secondary metabolite expression to stabilize desired chemical signatures across generations. Understanding these compounds is foundational to cannabis genetics work, though their specific effects remain an active area of horticultural research.

Breeders use secondary metabolite profiles—measured through chromatography and gas analysis—to phenotype plants and select for consistent chemotypes. Stable secondary metabolite expression across generations indicates successful strain stabilization and helps distinguish breeding lines in seed development programs.
