Erwinia carotovora subsp. carotovora에 의한 흰색꽃양배추 세균성 무름병
Bacterial Soft Rot of Cauliflower by Erwinia carotovora subsp. carotovora
초록
Bacterial soft rot was occurrenced on stems of cauliflower at a trial field of Alpine Agricultural Experiment Station, Kangwon-Do, Korea. the symptoms began as a small water-soaked lesion, which enlarged rapidly in diameter. The tissue within the affected region became slimy, disintegrating into a mushy mass of disorganized cells. The causal organism was isolated from the diseases lesions and was identified as Erwinia carotovora subsp. carotovora based on the morphological, physiological and chemical characteristics , and on the results of the Biolog program (Biolog Inc., U. S. A.). E. carotovora subsp. carotovora is the first described bacterium which causes bacterial soft rot on cauliflower in Korea.
