Short Day Induction
Short Day Induction refers to cannabis plants' photoperiodic response to reduced light cycles, typically triggering flowering when day length drops below a critical threshold (often 12–14 hours). This classification describes a key reproductive trait observed across many traditional landraces and photoperiodic cultivars. The mechanism involves the plant's circadian system detecting cumulative darkness, initiating hormonal shifts that redirect growth toward reproductive development. Short day induction is distinct from day-neutral or autoflowering genetics, which flower independent of light duration. Understanding this trait is essential for breeders working with outdoor crops, seasonal production schedules, and regional adaptation strategies.

Breeders leveraging short day induction genetics can design cultivation protocols tailored to specific growing regions and harvest windows. This trait remains foundational in developing photoperiodic hybrids and preserving regionally adapted landrace lines.
