Secondary Metabolite Storage

Secondary metabolite storage refers to the plant's capacity to accumulate and sequester terpenes, cannabinoids, and other volatile compounds within specialized cellular structures—primarily trichomes and vacuoles. Cannabis plants deposit these compounds as a survival mechanism and phenotypic trait influenced by genetics, environment, and cultivation timing. Breeders working in this category assess how efficiently a strain's genetics express, concentrate, and preserve these molecules during growth and post-harvest. Storage capacity varies significantly across lineages; some cultivars naturally accumulate higher terpene loads in their resinous glands than others. Understanding secondary metabolite storage helps breeders select parents that reliably produce aromatic, chemically rich offspring and informs preservation strategies for maintaining volatile profiles over time.

Breeders prioritize secondary metabolite storage traits when selecting parents for high-potency or high-terpene cultivars, as storage efficiency directly impacts the final chemical profile and shelf-life stability of preserved plant material. Genetic lines with robust storage capacity often show consistent resin production across generations, making them valuable foundation genetics for hybrid dev
