Seed Vigor Testing

Seed vigor testing is a standardized assessment method used to evaluate the germination potential and developmental capacity of cannabis seeds beyond simple germination rate. These tests measure parameters including radicle emergence speed, seedling root and shoot development, and stress tolerance under suboptimal conditions. Common protocols include cold tests, accelerated aging tests, and electrical conductivity measurements of seed leachate. Vigor testing provides breeders and seed producers with predictive data about field performance, storage stability, and genetic line consistency. Results inform decisions about seed lot acceptance, breeding stock selection, and storage protocols. High-vigor seeds typically establish faster and more uniformly, which is relevant for commercial cultivation operations and breeding program efficiency.

Breeders use vigor testing to identify elite parental lines and validate seed production quality across generations. Strong vigor metrics help ensure that selected genetics will perform consistently in diverse growing environments.
