Cut fruits and crushed leaves have a characteristic, very strong odor.
Fruit is too acid for fresh use but is used for marmalade.
The sour orange was widely used as a rootstock for other varieties prior to the appearance of the Tristizia virus disease, which affects trees on this stock. It is still used in areas where Tristizia is not important. The Bergamot oranges grown in Mediterranean areas for essential oil, belong in this group. There are no orchards of sour orange, but numerous plantings of a few trees serve as seed sources for rootstocks. No data, as not grown for fruit.
