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.

Cannabis Inflorescence Yield and Cannabinoid Concentration Are Not Increased With Exposure to Short-Wavelength Ultraviolet-B Radiation
TLDR
Using UV radiation as a production tool did not lead to any commercially relevant benefits to cannabis yield or inflorescence secondary metabolite composition, and the relative concentrations of individual terpenes varied by cultivar.
Simultaneous Quantitative and Qualitative Analysis of Flavonoids from Ultraviolet-B Radiation in Leaves and Roots of Scutellaria baicalensis Georgi Using LC-UV-ESI-Q/TOF/MS
TLDR
Different changes of different flavonoid under enhanced UV-B radiation indicate that induction on flavonoids is selective by enhanced UV/ESI/TOF radiation.
Chemical and Physical Elicitation for Enhanced Cannabinoid Production in Cannabis
TLDR
This chapter will explore the possible ecological roles of cannabinoids in cannabis and the potential utilization of these roles via biotic or abiotic elicitors.
Impact of Light Stress on Plant Based Medicinally Active Compounds
TLDR
Most of the results revealed increase in content of medicinal compounds under differentially exposed light conditions with maximum effect under sUV-B exposure, which can be further utilized in the production of medicinally active compounds.
From sunscreens to medicines: Can a dissipation hypothesis explain the beneficial aspects of many plant compounds?
TLDR
This review paper focuses on well‐described medicinal compounds, such as salicylic acid and cannabidiol and suggests, at least in animals, their activity reflects their evolved function in plants in relation to stress adaptation, which itself evolved to maintain dissipative homeostasis.

    The Botanical Review
  • 2015
TLDR
This review examines the evolving ways Cannabis has been used from ancient times to the present, and how human selection has altered the morphology, chemistry, distribution and ecology of domesticated forms by comparison with related wild plants.
An Update on Plant Photobiology and Implications for Cannabis Production
TLDR
By manipulating LED light spectra and stimulating specific plant photoreceptors, it may be possible to minimize operation costs while maximizing cannabis biomass and cannabinoid yield, including tetrahydrocannabinol and cannabidiol for medicinal and recreational purposes.
Plant-Derived Drugs Affecting GPRCs
TLDR
This work has shown that G-protein coupled signalling exists, but the signalling cycle is typically not activated by seven transmembrane-spanning receptors, and many plant secondary metabolites are known to affect human GPRCs.

TLDR
This review primarily deals with UV effects which might be relevant for plants under natural conditions of sunlight, and finds that UV-accelerated chlorosis in tobacco leaves is brought about indirectly by some substance stemming from the UV damaged epidermal cells.
Flavonoids and related phenolic compounds produced in the first internode of Sorghum vulgare Pers. in darkness and in light.
TLDR
The anthocyanin has been identified as an acylated cyanidin-3-glucoside, and possible C9 precursors of this pigment have been studied with isotope techniques and this material was examined in hopes that intermediates in anthocianin biosynthesis might be accumulated under appropriate conditions.
Quantitative variation in the chemical constituents of marihuana from stands of naturalizedCannabis sativa L. in East-Central Illinois
TLDR
Competition from other plants enhanced the content of the drug compounds, and this relationship strengthens the stress hypothesis, and work is underway to confirm this relationship.
The evolution of cannabinoid phenotypes inCannabis
TLDR
Although several aspects are being investigated, the research reported focuses mainly on the question of natural variation in Cannabis sativa, with particular emphasis on the cannabinoids the class of compounds responsible for the psychoactive properties of cannabis drugs.

The marijuana (Cannabis) constituents, cannabidiol, (−)-Δ9-trans-tetrahydrocannabinol, and (−)-Δ9-trans-tetrahydrocannabinol were found to be photoreactive. The only interconversion of these
The cannabinoid content of Cannabis sativa L grown in England
TLDR
Comparison of the present results with those for the same cannabis varieties grown in different parts of the world shows that all exhibit the same qualitative picture, that is, either THC‐rich or CBD‐rich, since this chemical composition seems independent of environmental conditions.
Mississippi-grown Cannabis sativa L: preliminary observation on chemical definition of phenotype and variations in tetrahydrocannabinol content versus age, sex, and plant part.
TLDR
Nine strains of Cannabis sativa L. sativa (marijuana) were grown for research by the University of Mississippi and the cannabinoid content was determined using GLC, and the material was divided into two chemical phenotypes according to cannabinoid content.

CULTIVATION, EXTRACTION, AND ANALYSIS OF CANNABIS SATIVA L. *
TLDR
Cannabis sativa L. sutiva was grown on three sites in Mississippi in 1968 and on two sites in 1969 and 1970, and it must be concluded that Cannabis is either a genus composed of more than 100 species or a single species that has not stabilized and that has many variations.
