The study most cited in favour of the specificity of the D–L test is Thornton and Nakamura (1972). [5] The authors themselves reported that the D–L test gave false positives, but declared the D–L test confirmatory when combined with the presence of cystolithic hairs, which marijuana plants possess. However, many plant species have such ...
Research has shown that Humulus lupulus (the plant that makes hops) and Cannabis sativa (also called hemp and marijuana) are closely related, [1] [a] and it may be possible to create novel cultivars of hops that express valuable chemicals similar to commercial hemp.
The flowers of Cannabis sativa plants are most often either male or female, but, only plants displaying female pistils can be or turn hermaphrodite. Males can never become hermaphrodites. [3] It is a short-day flowering plant, with staminate (male) plants usually taller and less robust than pistillate (female or male) plants.
The mixture of cannabinoids produced by a plant is known as the plant's cannabinoid profile. Selective breeding has been used to control the genetics of plants and modify the cannabinoid profile. For example, strains that are used as fiber (commonly called hemp ) are bred such that they are low in psychoactive chemicals like THC.
Sarcodes is the monotypic genus of a north-west American flowering springtime plant in the heath family , containing the single species Sarcodes sanguinea, commonly called the snow plant or snow flower. It is a parasitic plant that derives sustenance and nutrients from mycorrhizal fungi that attach to tree roots
The Oklahoma Medical Marijuana Authority has filed 165 petitions for revocation against licensed grow facilities for failure to have signage required by law, the agency announced this week.
These varieties have been cultivated to contain a high percentage of cannabinoids. Several varieties of cannabis, known as hemp, have a very low cannabinoid content, and are instead grown for their fiber and seed. Due to the legal status of the plant in many jurisdictions, Cannabis plant varieties are at high risk of biopiracy. [3] [4]
(The Center Square) – Even though marijuana is legal in Illinois, the state’s highest court has ruled that the smell of raw cannabis is enough for police to search a vehicle. The case stems ...
