Abstract

A destructive disease was observed in 2003 on Mazafati date palms in Golgeh-e-Chah Hashem (Iranshahr, Bluchestan). Affected plant tissues the from heart and rachis sectors were suspended in distilled water and streaked onto PDA and NA media. Plates were incubated at 28oC for 48 h. Milky color colonies were consistently isolated on PDA. Discrete colonies characterization tests. Eleven isolates were used in the identifying experiments, 7 from rotten heart and 4 from leaf rachis end were used for identification tests. Cultures on PDA were subjected to morphological and biochemical tests. Colonies were umbonate with undulate margins (fried-egg shape). The bacterium grew at 36oC and in 6% NaCl and YDC media.The bacterium was negative for urease and oxydase activity. Glucose, trehalose, celobiose, maltose and lactose were used. Tests for indol production, H2S from cystein, acetoin, pectat degradation and production of gas from glucose, gelatin liquefaction, nitrate production and phosphatase were positive. Hypersensitivite reaction on tobacco was positive. The bacterial isolates from date palm were identified as Erwinia chrysanthemi. This is the first report of this bacterium in Iran. This bacterium has been reported as the causal agent of sudden decline disease on date palm in Saudi Arabia by M.Y. abdallah in 2001 (Plant Dis. 85: 24-26).
