'''The Type of Orange Tree Used for Grafting ''' | |||

:(San Francisco Gate) | |||
The citrus tree you plant in your backyard is not growing on its own roots. The grapefruit, tangerine or other citrus is grafted onto a separate rootstock. Grafting gives disease-resistance, improved cold hardiness and dwarfing. Through the history of citrus-growing, citrus rootstock trees changed due to new diseases and plant pests that attack rootstocks. More than 12 kinds of citrus rootstocks are used, depending on local climate and soil factors, on diseases present in a geographic area, and on degree of scion dwarfing. Three types of oranges are used as rootstocks. | |||
:Sour Orange | |||
Widely grown in the Mediterranean area as an ornamental and as a crop plant in its own right, sour orange (Citrus aurantium), also called bitter orange or Seville orange, is used for marmalade. Bitter orange oil, called petitgrain, is used in foods, cosmetics and aromatherapy. Sour orange has been one of the most widely used citrus rootstocks. Now it isn't used at all in California, Florida or anywhere tristeza -- or quick decline virus disease -- occurs because of sour orange's susceptibility to tristeza, which kills the tree. Otherwise, sour orange gives excellent cold hardiness, gives the best flavor and texture to fruits of the grafted budstock, and has good resistance to other diseases. | |||
:Sweet Orange | |||
Sweet orange (Citrus sinensis or C. aurantium var. sinensis) is the original orange, thought to have originated in China or southeastern Asia, and brought to Europe sometime between 1450 and 1500 by Spanish or Portuguese explorers. Oranges made their way to the New World with Spanish priests as they journeyed to South America, Mexico and the American Southwest. Sweet orange rootstock gives good cold hardiness, good taste to budstock fruit, and good resistance to viral diseases and blight. However, it is not resistant to the fungal disease Phytophthora foot rot, which limits its use in Florida. | |||
:Trifoliate Orange Other Than "Flying Dragon" | |||
Trifoliate orange, also called hardy orange (Poncirus trifoliata), is a small tree or large shrub native to eastern Asia that bears small, fragrant yellow fruits resembling miniature oranges. They taste somewhat like lemons, and are used in beverages and marmalade. The trees are deciduous in winter and grow in U.S. Department of Agriculture plant hardiness zones 5 through 9. As a rootstock, trifoliate orange provides an added 3 degrees Centigrade of cold hardiness over other species. It gives good-tasting but smaller fruit and smaller stature to budstock. The cultivar "Roubidoux" produces trees that are 15 to 20 percent smaller than trees grown on the cultivar "Pomeroy." Smaller trees reduce costs for commercial growers because of ease in harvesting and tree maintenance. These cultivars are susceptible to blight, limiting their use in Florida. | |||
:Trifoliate Orange "Flying Dragon" | |||
"Flying Dragon" (P. trifoliata "Monstrosa") is a semi-dwarf form of hardy orange that has contorted stems and large curved thorns. As a rootstock, "Flying Dragon" confers extreme dwarfing to the scion, including smaller but rich-tasting fruits. It is resistant to blight disease and tolerant of most viruses. A drawback is the plant's susceptibility to exocortis viroid, a disease that causes severe stunting and bark scaling in the scion. | |||
