Grafting Techniques

Grafting techniques in cannabis cultivation involve joining plant tissues from different genetic sources to create chimeric or multi-varietal specimens. Common approaches include cleft grafting, where a scion is inserted into a split rootstock, and splice grafting, which creates a direct connection between two stems. These methods are primarily used in breeding programs and horticultural research to study genetic expression, combine desired traits from multiple parents, or propagate rare phenotypes. Grafting allows breeders to observe how different genotypes interact when sharing root systems, providing data on compatibility and vigor. Success rates vary significantly based on technique, plant material compatibility, and environmental conditions. This classification is distinct from conventional hybridization and serves specialized research and propagation goals.

Breeders employ grafting to rapidly assess phenotypic compatibility between genetics before committing to full breeding cycles, and to preserve elite genotypes while maintaining rootstock vigor. Grafting trials generate data on stock-scion interactions that inform strain development and selection strategies.
