Abstract

A fruit soft rot caused by Mucor piriformis occurred on sweet persimmon storages in Jinju, Changwon and Gimhae, Gyeongnam province, Korea, 2003. The disease infection usually started from wounding after cracking of fruits. At first, the lesions started with water soaked and rapidly softened and diseased lesion gradually expanded. Colonies on potato dextrose agar at 20degrees C were whitish to olivaceous-buff Sporangia were globose, black and 96~153microm in size. Sporangiophores were 26~42microm in width. Sporangiospores were ellipsoid and 5.8~10.6x4.3~7.6microm in size. Columella was obovoid, cylindrical-ellipsoidal, pyriform, subglobose and 80~125microm in size. Optimal temperature for mycelial growth was 20degrees C on PDA. The causal organism was identified as M. piriformis. This is the first report of fruit soft rot on sweet persimmon caused by M. piriformis in Korea.
