| Summary: | Rhizopus soft rot of lily (Lilium longiflorum) caused by Rhizopus oryzae was observed in the experimental field
in Taean Lily Experiment Station in Korea, 2012. The typical symptoms were water-soaked lesions on bottom
stem and leaf rot. The lesion rapidly expanded and the plant was softened totally. The fungus grew vigorously
at an optimum temperature (25oC) and brownish colony and black sporangia were formed on potato
dextrose agar medium. Sporangiophores formed on end of sporangia were sub-globose, brownish and 6-10
μm in size. Sporangia were globose, blackish and 87-116 μm in size. Sporangiospores were irregularly oval
and sub-globose, brownish 4-8 μm in size. On the basis of mycological characteristics, analyzing sequences of
internal transcribed spacer region of ribosomal DNA, and pathogenicity test on host plants, the causal fungus
was identified as R. oryzae. This is the first report of Rhizopus soft rot on lily caused by R. oryzae in Korea. |
