Segra International is a Canadian cannabis tissue culture and micropropagation company headquartered in Richmond, British Columbia, with a Health Canada-licensed nursery facility. The company has industrialized plant tissue culture for cannabis: producing clean, genetically uniform plantlets at scale through meristem propagation and cryopreservation.
Segra's Plant Tissue Culture Division pioneers cannabis tissue culture protocols, micropropagation automation, and full-scale production testing from plantlet through flower. The company's quality assurance diagnostics include cultivar DNA fingerprinting and pathogen detection. Over five years, Segra has developed industry-leading diagnostics for hop latent viroid (HLVd) and other cannabis pathogens.
Tissue culture matters because it is one of the few reliable ways to clean a cannabis line of latent pathogens and to bank a line genetically without losing its phenotype across generations.
Segra International contributes tissue culture expertise to the Martian Grow research program and provides the micropropagation and cryopreservation infrastructure for banking genetic lines.
For an orbital-genetics program, genetic banking is not optional. Each flight produces a small number of spaceflown seeds that become the foundation for future cultivar lines. Those seeds must be cleaned of any pathogen contamination, verified as genetically identical to the pre-flight baseline, and banked in a form that can be propagated without genetic drift. Segra's tissue culture capability is the infrastructure that makes that possible at a professional standard.
