Colchicine Treatment

Colchicine treatment is a horticultural technique used in cannabis breeding to induce polyploidy—doubling or multiplying the chromosome sets in plant cells. While not a terpene itself, colchicine application is a preservation and breeding tool occasionally referenced in cannabis genetics literature. The alkaloid, derived from autumn crocus plants, disrupts spindle fiber formation during cell division, resulting in offspring with altered genetic ploidy. Breeders working in polyploid development sometimes employ this method to create tetraploid or hexaploid cannabis lines, which can exhibit distinct morphological and biochemical profiles. This technique requires careful dosing and timing to avoid plant damage. Colchicine-treated lines remain uncommon in commercial cannabis breeding due to regulatory complexity and unpredictable phenotypic outcomes.

Polyploidy induction via colchicine can modify plant vigor, yield potential, and secondary metabolite expression. Breeders researching chromosome manipulation use this tool to expand genetic diversity and explore novel trait combinations in controlled research settings.
