Heavy Metal Tolerance

Heavy metal tolerance is not a terpene but rather a plant-level trait that some cannabis cultivars display in their ability to accumulate or sequester heavy metals from soil with reduced translocation to flowers and leaves. This characteristic is relevant to cultivation in contaminated or remediation contexts, as certain genetics may preferentially store metals in roots and stems rather than harvestable biomass. Lineage records and breeding documentation occasionally reference this trait when selecting parents for specific growing environments or sustainability goals. The mechanisms involve root-level biochemistry and soil chemistry interactions rather than volatile aromatic compounds. Understanding cultivar-specific metal accumulation patterns is important for growers in areas with legacy soil contamination or those practicing phytoremediation.

Breeders working in remediation-focused programs or cultivation zones with known soil contamination sometimes select for or document metal-accumulation phenotypes. This trait is typically assessed through tissue testing of parent plants and their offspring rather than through aromatic or cannabinoid profiling.
