Terpene Secondary Metabolism

Terpene secondary metabolism refers to the biochemical pathways through which cannabis plants synthesize and accumulate terpenes beyond primary growth requirements. Rather than being essential for basic plant survival, these volatile compounds develop as adaptive responses to environmental stress, pest pressure, and genetic expression patterns. Secondary metabolite production in cannabis typically increases during flowering and in response to UV exposure, nutrient availability, and temperature fluctuations. Understanding these pathways helps breeders identify genetic lines with consistent terpene profiles and predict how cultivation conditions influence aromatic expression. This metabolic process represents a key intersection between plant genetics, environmental triggers, and the final aromatic complexity observed in finished cannabis material.

Breeders leverage knowledge of secondary terpene metabolism to select parent plants that reliably produce desired volatile profiles across generations. By understanding the environmental and genetic factors controlling these pathways, breeders can develop cultivars with predictable aromatic characteristics and stability across different growing conditions.
