Abstract
The damaging effects of UV-B radiation have apparently affected the amounts of ultraviolet-absorbing secondary compounds in some plants. A similar role for Δ9 tetrahydrocannabinol may explain the high levels of this compound inCannabis from areas of intense ambient UV-B. Further research is needed to determine whether UV-B radiation serves only as a selection pressure or if UV-B-induced stress may also directly stimulate production.
