The definitive test for diagnosing this condition is by detecting the levels of cortisol in the body. Normally the adrenocorticotropic hormone (ACTH) is produced by the pituitary gland, which then stimulates the adrenal glands to release their hormones.
The Code then defines a cultivar as a taxonomic unit within the classification category of cultivar. This is the sense of cultivar that is most generally understood and which is used as a general definition. A cultivar is an assemblage of plants that (a) has been selected for a particular character or combination of characters, (b) is distinct, uniform and stable in those characters, and (c) when propagated by appropriate means, retains those characters.
The naming of cultivars is an important aspect of cultivated plant taxonomy, and the correct naming of a cultivar is prescribed by the Rules and Recommendations of the International Code of Nomenclature for Cultivated Plants (the ICNCP, commonly known as the Cultivated Plant Code).
