Plant Secondary Metabolites

Plant secondary metabolites are organic compounds synthesized by cannabis plants beyond primary metabolic needs, including terpenes, cannabinoids, and flavonoids. These molecules accumulate in trichomes and other plant tissues, often functioning as pest deterrents, UV protectants, or signaling compounds in natural environments. Secondary metabolites vary significantly across cultivars and are influenced by genetics, growing conditions, harvest timing, and post-harvest handling. In cannabis breeding and research, these compounds are studied for their chemical diversity and potential roles in plant physiology and consumer experience. Understanding secondary metabolite production helps breeders select for specific chemotypes and preserve desirable genetic expression across generations.

Breeders track secondary metabolite profiles to stabilize unique chemotypes and maintain consistency within strain families across multiple generations. Selection pressure on metabolite-rich parents is common practice in developing cultivars with distinctive aromatic and chemical signatures.
