Interrelationships of glandular trichomes and cannabinoid content. I: Developing pistillate bracts of Cannabis sativa L. (Cannabaceae).
Gland number and cannabinoid content for three clones of Cannabis were compared. Cannabinoid levels and mature glands were quantified throughout progressive stages of pistillate bract development in order to define possible interrelationships between glands and cannabinoids. Similar trends occurred among the clones for each gland type while individual cannabinoids displayed a different pattern ...
متن کاملPlastid development in disc cells of glandular trichomes of Cannabis (Cannabaceae).
Plastids in lipophilic glandular trichomes of chemically fixed (CF) and high pressure cryofixed-cryosubstituted (HPC-CS) bracteal tissues of Cannabis were examined by transmission electron microscopy. In CF preparations, plastids in disc cells prior to secretory cavity formation possessed several lobed and dilated thylakoid-like features. In glands with secretory cavities, thylakoid-like featur...
متن کاملHemp (Cannabis sativa L.) and abortion.
The correspondence of Zias et al. (1993), related the finding of carbonized matter containing tetrahydrocannabinol (THC), the primary psychoactive component of marijuana, in the abdomen of an adolescent girl who apparently died in childbirth around 400 AD. The researchers’s hypothesis was that Cannabis was administered to women in child birth to relieve pains and increase uterine contractions b...
متن کاملA chemotaxonomic analysis of cannabinoid variation in Cannabis (Cannabaceae).
Cannabinoids are important chemotaxonomic markers unique to Cannabis. Previous studies show that a plant's dry-weight ratio of Δ(9)-tetrahydrocannabinol (THC) to cannabidiol (CBD) can be assigned to one of three chemotypes and that alleles B(D) and B(T) encode alloenzymes that catalyze the conversion of cannabigerol to CBD and THC, respectively. In the present study, the frequencies of B(D) and...
متن کاملThe inheritance of chemical phenotype in Cannabis sativa L.
Four crosses were made between inbred Cannabis sativa plants with pure cannabidiol (CBD) and pure Delta-9-tetrahydrocannabinol (THC) chemotypes. All the plants belonging to the F(1)'s were analyzed by gas chromatography for cannabinoid composition and constantly found to have a mixed CBD-THC chemotype. Ten individual F(1) plants were self-fertilized, and 10 inbred F(2) offspring were collected ...
