claimCBD yields from field-grown hemp plants often differ from the yields claimed in sales catalogs due to the genetic heterozygosity of the seeds.
referenceThe two main cannabinoids produced by cannabis are Δ9-THCA and cannabidiolic acid (CBDA), according to Andre et al. (2016) and Hurgobin et al. (2021).
referenceGrassa et al. (2021) published 'A new cannabis genome assembly associates elevated cannabidiol (CBD) with hemp introgressed into marijuana' in New Phytologist, identifying a genetic association between CBD levels and hemp introgression.
referenceCannabinoids THCA and CBDA are generated via a common pathway utilizing cannabigerolic acid (CBGA), which is acted upon by THCA synthase or CBDA synthase, according to Tahir et al. (2021).
claimGenetic heterozygosity can be problematic for hemp growers requiring stable genetics for consistent high CBD production because undesirable traits may be expressed during the breeding process.
claimGiupponi et al. (2020) found that industrial hemp grown in mountainous regions with increased UV light exposure showed altered production of CBDA and cannaflavins.
referenceHakim et al. (1986) published 'Effect of the climate on the content of a CBD-rich variant of cannabis' in Fitoterapia, which investigates the relationship between climate and CBD content in specific cannabis variants.
claimHemp varieties are designed for high CBD production while maintaining THC levels below 0.3%.
measurementCaplan et al. (2019) demonstrated that subjecting cannabis plants to drought for 11 days during the flowering stage increases THC levels by 50% and CBD levels by 67%.
referenceLaverty et al. (2019) published 'A physical and genetic map of Cannabis sativa identifies extensive rearrangements at the THC/CBD acid synthase loci' in Genome Research, mapping genetic rearrangements related to THC and CBD production.
measurementCampbell et al. (2019) found that genetics account for 80% of THC variation and 83% of CBD variation in cannabis, while environmental conditions account for 1.7% of THC variation and 6% of CBD variation.
referenceGrassa et al. (2018) released a preprint titled 'A complete cannabis chromosome assembly and adaptive admixture for elevated cannabidiol (CBD) content' on bioRxiv, detailing chromosome assembly and CBD-related genetic admixture.
