Investigation on citrus stubborn disease in Mazandaran


, : Investigation on citrus stubborn disease in Mazandaran. Iranian Journal of Plant Pathology 28(1-4): 35-37, 95-100

Spiroplasma citri was cultured from fruits of Stubborn - infected Thomson navel and Hybrid No. 4 Orange, and Darabi (Citrus grandis) collected from Tonekabon, Ghaemshahr, Sari and Neka (Iran.) The pathogen could only be isolated from trees showing stunting, unseasonal flowering, stylar-end greening and lop-sided fruits. Electrophoretic patterns of cell proteins of the isolates from various areas of the province were identical. The isolates reacted with an antiserum against C-3B strain of S. citri in agar gel diffusion test. Stubborn was sporadic in the region and Thomson navel seemed to be the major source of infection in Mazandaran province.
