Flowering Stage

Flowering stage refers to the developmental period when cannabis plants transition from vegetative growth to reproductive maturity, typically triggered by photoperiod changes or internal maturation cues. During this phase, plants allocate energy toward calyx and trichome development rather than foliar growth. Terpene production patterns shift substantially during flowering; some compounds increase in concentration while others diminish or transform chemically. This stage is critical for breeding programs because terpene profiles—and their stability across generations—are often evaluated during late flowering when volatile expression reaches peak levels. Understanding flowering-stage terpene expression helps breeders identify which genetics consistently produce desired aromatic profiles across environmental conditions.

Breeders closely monitor terpene development throughout flowering to select parent plants with stable, heritable aromatic traits. Late-flowering terpene sampling has become standard practice for phenotype assessment and line stabilization in breeding programs.
