Abstract

Soft rot symptom was observed on lily bulb in the fields and at a low temperature storage house from 1999 to 2000 in Korea. The small dark-brown lesion appeared on the bulb, and enlarged and developed into the inner scales of the bulb. The bulb became water soaked and gave out unpleasant odor. Two different pathogenic bacteria were isolated from infected tissues. The causal bacteria were identified as Pectobacterium carotovorum subsp. carotovorum (Erwinia carotovora subsp. carotovora) and Pseudomonas marginalis based on bacteriological characteristics. Pathogenicity of the bacteria was proven by Koch's postulations. This is the first report of bacterial soft rot of lily bulb in Korea caused by the two bacteria.
