Illuminating Cannabis sativa L.: The Power of Light in Enhancing C. sativa Growth and Secondary Metabolite Production
Abstract Light is crucial for higher plants, driving photosynthesis and serving as a powerful sensory signal that profoundly modulates growth, development, physiological functions, hormone activation, and biochemical pathways. Various light parameters—quality, intensity, composition, and [...]
LED spectra and defoliation independently shape canopy architecture and cannabinoid yield in indoor Cannabis cultivation
Abstract Cannabis growers often use light spectra and defoliation regimes to alter the growth of their plants. While several studies consider the impact of these practices separately, there are no reports of how these [...]
Crop steering through osmotic stress can reduce height but reduced yield in medical Cannabis
Abstract Background Precision water stress, achieved via osmotic stress, has the potential to control plant size and improve crop quality without reducing yield, but results across species and cultivars have been inconsistent. Methods This [...]
Effect of Propagation Techniques on Growth, Development, Oil Yield, and Quality of Medicinal Cannabis (Cannabis sativa) Found in Lusikisiki, Eastern Cape, South Africa
Abstract This study investigated the influence of cutting techniques on the growth, development, yield, and oil quality of Cannabis sativa found in the Eastern Cape Province. The greenhouse pot experiment was conducted at Dohne [...]

Cannabis sativa genotypes with larger leaf areas have higher potential to adjust stomatal size and density in response to water deficit: The effect on stomatal conductance and physiological stomatal behaviour
Abstract Effective stomatal control is fundamental to successful plant responses to water deficit stress. Control of stomatal conductance (Gs) can be exerted through modification of stomatal morphology (size and density) in newly developing leaves, [...]
The Plant of Many Scents: Unraveling the Odorant Composition of Selected CBD Hemp Cultivars
Abstract This study presents the first comprehensive sensory-guided investigation into the odor-active compounds of dried hemp (Cannabis sativa L.) flowers. Using gas chromatography-olfactometry (GC-O) in combination with aroma extract dilution analysis (AEDA), 52 odor-active [...]
Cannabis glandular trichomes alter morphology and metabolite content during flower maturation
Summary The cannabis leaf is iconic, but it is the flowers of cannabis that are consumed for the psychoactive and medicinal effects of their specialized metabolites. Cannabinoid metabolites, together with terpenes, are produced in [...]
Accumulation of somatic mutations leads to genetic mosaicism in cannabis
Abstract Cannabis (Cannabis sativa L.) is typically propagated using stem cuttings taken from mother plants to produce genetically uniform propagules. However, producers anecdotally report that clonal lines deteriorate over time and eventually produce clones [...]
