Influence of different UV spectra and intensities on yield and quality of cannabis inflorescences
Abstract The raising economic importance of cannabis arouses interest in positively influencing the secondary plant constituents through external stimuli. One potential possibility to enhance the secondary metabolite profile is the use of UV light. [...]
High air temperature reduces plant specialized metabolite yield in medical cannabis, and has genotype-specific effects on inflorescence dry matter production
Abstract Improving and standardizing the production of medical cannabis is essential for developing consistent and uniform medical products. Key challenges are achieving high concentrations of plant specialized metabolites (PSMs), uniformity of PSMs at different [...]
F1 Hybrid Seed Can Enhance Cannabis Crop Uniformity and Yield
Abstract Cannabis (Cannabis sativa) growers seek greater crop uniformity and yield; however, use of vegetatively propagated plants has several drawbacks. There is increased interest in F1 hybrid seed, especially for flower production. Plant growth [...]
Cultivation Strategies to Modify Biomass Partitioning and Improve Yield in Controlled-environment Production of High-cannabidiol Cannabis (Cannabis sativa L.)
Abstract Two common challenges reported by cannabis growers are low yields and small profit margins. Although recent research of cannabis yield has focused on lighting and nutrition, little research has examined how changes in [...]

Minor, Nonterpenoid Volatile Compounds Drive the Aroma Differences of Exotic Cannabis
Abstract Cannabis sativa L. produces a wide variety of volatile secondary metabolites that contribute to its unique aroma. The major volatile constituents include monoterpenes, sesquiterpenes, and their oxygenated derivates. In particular, the compounds ß-myrcene, [...]
Chemical Composition of Commercial Cannabis
Abstract Cannabis is widely used for medicinal and recreational purposes. As a result, there is increased interest in its chemical components and their physiological effects. However, current information on cannabis chemistry is often outdated [...]
Taming THC: potential cannabis synergy and phytocannabinoid-terpenoid entourage effects
Abstract Tetrahydrocannabinol (THC) has been the primary focus of cannabis research since 1964, when Raphael Mechoulam isolated and synthesized it. More recently, the synergistic contributions of cannabidiol to cannabis pharmacology and analgesia have been [...]
Flavonoids in Cannabis sativa: Biosynthesis, Bioactivities, and Biotechnology
Abstract Although Cannabis sativa synthesizes a wide range of phytochemicals, much attention has been primarily given to two phytocannabinoids, Δ9-tetrahydocannabinol (THC) and cannabidiol (CBD), due to their distinctive activities in humans. These bioactivities can [...]
