Abstract

During 2004 to 2005 date PALM regions in Fars province were surveyed and samples with symptoms of decline and spear, rachis, pinnea and BUD ROT, discoloration of leaves, vascular browning, and accumulation of bacterial slime in stalk were collected. A total of 40 strains were isolated from infected samples using EMB, CPG and YDC media. Strains were gram and oxidase negative, catalase positive and facultative anaerobs with green metallic colonies on EMB and cream-white colonies on CPG medium. The strains were identified as Pectobacterium carotovorum subsp. carotovorum (Pcc) and Dicheya chrysanthemi on the basis of standard physiological, biochemical and nutritional properties. Representative strains were compared by physiological and biochemical characters, pathogenicity test, protein electrophoretic pattern and polymerase chain reaction (PCR). Protein electrophoretic pattern of the strains identified as P. carotovorum subsp. carotovorum were similar to a reference strain of Pcc. In PCR assay, 19 representative strains identified as P. carotovorum subsp. carotovorum produced predicted 550bp PCR products with EXPCCF/ EXPCCR primers but no PCR products were obtained from 3 strains identified as D. chrysanthemi with the primers.Artificial inoculation of one Pcc and one D. chrysanthemi strain to PALM trees led to the formation of rot, tissue browning and cholorosis of leaves, although tissue maceration of green pepper was obvious in the most strains.
