Methyl Jasmonate and Ammonium Bicarbonate: Distinct and Synergistic Impacts on Indoor Cannabis Production Dynamics
Abstract As high-CBD cannabis (Cannabis sativa L.) gains legal and commercial relevance in the United States, studies evaluating how external inputs impact critical traits remain limited. This study investigates the effects of methyl jasmonate [...]
Long-days during the last two weeks before harvest applied to short-day medicinal cannabis can improve inflorescence yield
Abstract Most medicinal cannabis cultivars are short-day plant requiring a short photoperiod to induce flowering. This limits the light and consequently photosynthesis, and growth. In short-day chrysanthemum, extending a short photoperiod with blue light [...]
The Role of Jasmonates in Modulating Growth, Trichome Density, and Cannabinoid Accumulation in Cannabis sativa L.
Abstract Jasmonates have emerged as a prominent elicitor for enhancing trichome development and cannabinoid production in Cannabis sativa L. (cannabis). These glandular trichomes synthesize and store important cannabinoids, including tetrahydrocannabinol (THC) and cannabidiol (CBD), [...]
Effect of far-red and blue light on rooting in medicinal cannabis cuttings and related changes in endogenous auxin and carbohydrates
Abstract Stem cuttings are used in the commercial cultivation of many crops, including medicinal cannabis, to produce large numbers of uniform and genetically identical plants. Light is an important environmental factor determining the success [...]

Bracts, Buds, and Biases: Uncovering Gaps in Trichome Density Quantification and Cannabinoid Concentration in Cannabis sativa L.
Abstract Trichomes in cannabis (Cannabis sativa L.) are specialized structures responsible for cannabinoid and terpene biosynthesis, making their density a critical parameter for both research and industrial applications. However, consistent trichome density assessment remains [...]
Mother transformer: A High-Throughput, Cost-Effective in Planta Hairy Root Transformation Method for Cannabis
Abstract Background Hairy root (HR) transformation assays mediated by Agrobacterium rhizogenes, both in vitro and ex vitro, are essential tools in plant biotechnology and functional genomics. These assays can be significantly influenced by various [...]
Unravelling herbicide stress and its impact on metabolite profiling in Cannabis sativa: an investigative study
Abstract Background Cannabis sativa L., renowned for its versatility in pharmaceutical, textile, and cosmetic industries, is highly susceptible to several agronomic and environmental factors, particularly herbicides. These chemical agents, while commonly used for weed [...]
Variability of total THC in greenhouse cultivated dried Cannabis
Abstract Natural variation in secondary metabolites is commonplace in organic matrices, including consumable fruits and vegetables. However, absolute concentration and variation of secondary metabolites are generally not of concern to consumers. Cannabis sativa and C. [...]
