Abstract
|
|
|
The bacteria isolated from mulberry trees which had shoot soft rot symptoms occurred after intermediate cuttings during autumn rearing season were indentified. External morphology of the bacteria showed rod shape with peritrichous flagella, and were facultative anaerobes in oxygen requirement test.
The bacteria easily putrefied the slices of potato and carrot when they were placed on to the center of sliced surfaces, and the bacteria, also, iniciated rapid development of soft rot symptoms on mulberry leaves in pathogenesity test.
The results of morphological, physiological and pathological tests on the bacteria suggested that the isolate could be a strain of Erwinia carotovora subsp. carotovora.
