Terpene Expression Timelines

Terpene expression timelines describe the sequential release and development of aromatic compounds throughout a cannabis plant's lifecycle—from vegetative growth through flowering and post-harvest curing. Different terpene families emerge at distinct developmental stages; some are present early in growth, while others accumulate primarily during late flowering or develop further during drying and curing. Understanding these temporal patterns is valuable for breeders selecting for particular aroma profiles and for cultivators optimizing harvest timing. Lineage records frequently report that parent plants can influence not just which terpenes appear, but *when* they become dominant. This phenological aspect adds complexity to breeding work targeting stable, reproducible terpene profiles across generations.

Breeders working with terpene expression timelines focus on selecting parent plants that demonstrate consistent temporal patterns, since early-emerging versus late-stage terpene dominance can affect both sensory outcomes and extraction efficiency. Stabilizing these developmental sequences across generations requires multi-year observation and careful phenotype tracking.
