Uv B Tolerance

UV-B tolerance is not a terpene, but rather a plant trait influenced by secondary metabolites including cannabinoids and flavonoids that help cannabis plants withstand ultraviolet-B radiation exposure. In breeding programs, cultivars displaying enhanced UV-B resilience often show elevated levels of protective compounds that develop in response to environmental stress. This characteristic is particularly relevant for outdoor and greenhouse cultivation in high-altitude or equatorial regions where UV-B intensity is elevated. Breeders working in cannabis genetics have noted correlations between certain landrace populations and improved UV-B stress response, though the genetic architecture underlying this trait remains incompletely mapped.

Breeders targeting outdoor-hardy cultivars often select for UV-B tolerance to improve plant vigor and reduce photooxidative damage. This trait is particularly valuable in breeding programs focused on resilient, sun-exposed growing environments where natural UV-B exposure is significant.
