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.
A cultivar is not the same as a botanical variety, and there are differences in the rules for the formation and use of the names of botanical varieties and cultivars. In recent times the naming of cultivars has been complicated by the use of statutory plant patents and plant breeders' rights names.
