Bergamot orange Bergamot orange Citrus bergamia, the bergamot orange (pronounced ), is a fragrant citrus fruit the size of an orange, with a yellow or green color similar to a lime, depending on ripeness. Genetic research into the ancestral origins of extant citrus cultivars found bergamot orange to be a probable hybrid of lemon and bitter orange. Extracts have been used to scent food, perfumes, and cosmetics. Use on the skin can increase photosensitivity, resulting in greater damage from sun exposure. The word bergamot is etymologically derived from the Italian word ""bergamotto"", ultimately of Turkish origin: "bey armudu" or "bey armut" ("prince's
Citrus tristeza virus host types under the proper conditions, and especially in "Citrus" trees grafted onto sour orange rootstock. The host will develop pits in the trunk and stem. This results is decreased tree vigor and reduced fruit yield. This is typically caused by the more virulent strains of CTV. The third major symptom of CTV infection is seedling yellows. This tends to occur on sour orange, Natsudaidai, lemon and buntan. Symptoms include yellowing of foliage and general dieback. CTV is classically diagnosed by graft-inoculating a Mexican lime ("Citrus aurantifolia") with tissue from a diseased plant. The Mexican lime will develop highly predictable
