Field symptoms of exocortis virus disease of citrus on Shamouti sweet orange

Acta Horticulturae (53): 381-390

Field symptoms of exocortis virus disease of citrus on Shamouti sweet orange

Nine-year-old trees budded on rough lemon developed longitudinal splits on trunks and large branches. As the trunks increased in girth the splits widened and appeared as patches. The cambial surface became green and there was a prominent bulge at the bud union. Gum exudation appeared on some of the trunks and most of the leaves were greatly reduced in size. Indexing on Etrog citron Arizona 861 revealed severe exocortis virus symptoms.

Fast microextraction method and SDS-KAc method were evaluated for the detection of Citrus exocortis viroid (CEVd) in citron (cv. Etrog). SDS-KAc was preferable as it eliminated non-specific bands. The distribution of CEVD in young leaves, mature l...
