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 Difference between Plant Variety and Cultivar. All botanical names consist of at least two parts, a genus and species names. So, lily of the valley is known as Convallaria majalis, and Norway maple is Acer plantaoides. Sometimes, however, the name of a plant has three names, genus species, and cultivar or variety.
