Metabolite Distribution

Metabolite distribution refers to how cannabis plants allocate secondary metabolites—cannabinoids, terpenes, and flavonoids—across different tissues and developmental stages. This classification examines spatial and temporal patterns: whether compounds concentrate in trichomes, leaves, flowers, or stems, and how these patterns shift from seedling through senescence. Breeders and researchers track metabolite distribution to understand trait heritability, predict phenotypic expression, and optimize cultivation practices. Distribution patterns are influenced by genetics, environment, and plant age, making them a key variable in breeding programs seeking consistent chemotypes. Understanding these patterns informs seed selection, harvest timing, and post-harvest handling protocols.

Breeders monitor metabolite distribution patterns to identify stable genetic backgrounds and predict offspring performance. Lines showing consistent, heritable distribution traits are prioritized for stabilization and backcrossing programs.
