초록

Rhizopus soft rot caused by Rhizopus stolonifer on June, 2008 occurred on Rubus crataegifolius Bunge in the
box at Jinju City Wholesale Market of Agricultural Products at Gyeongnam province in Korea. The infected
fruits were rapidly water-soaked, softened, black and eventually rotted. The symptoms occurred after infecting
wounds at harvest time. The colony were white to light brown, formed much sporangiospores. The optimum
temperature of the fungus on potato dextrose agar was 30oC. Sporangiophores were 12~25 μm in width.
Sporangia were globose or hemispheric, white at first and gradually to black, and 82~195 μm in size. Columella
were hemispheric, and 70~92 μm in size. Sporangiospores were irregular round or oval, brownishblack
and 9~21×7~8 μm in size. On the basis of symptom, mycological characteristics and pathogenicity of the
fungus, the causal fungus was identified as Rhizopus stolonifer. This is the first report of Rhizopus soft rot by
R. stolonifer on R. crataegifolius in Korea.
