Tristeza, or quick decline, of many commercial varieties of Citrus on sour orange (C. aurantium) rootstocks; the severity of symptoms depends on the virus strain, some strains causing almost no damage. Tristeza was first recognized as a scion/rootstock disease, no symptoms appearing in plants on tolerant rootstocks. Symptoms include rapid wilting of trees on sour orange rootstocks, and root damage; honeycombing often occurs immediately below the bud union on the sour orange stock. When trees decline rapidly, a yellow-brown stain is sometimes present at the bud union and on the inner surface of the bark patch. Stunting of young trees propagated on sour orange rootstocks occurs in Florida. Stem-pitting and loss of plant vigour occurs on grapefruit (C. paradisi) scions in South Africa, Australia, and in the Far East; and stem-pitting regardless of the rootstock occurs on certain sweet orange (C. sinensis) varieties, e.g. Pera in Brazil, California and the Far East. Probably the most devastating disease caused by the virus is dieback of limes (C. aurantifolia) irrespective of rootstock. Certain Passiflora species in the jungles of South America show serious wilt symptoms.
