Alternaria mali에 의한 아로니아 점무늬낙엽병 = Alternaria Leaf Spot Caused by Alternaria mali on Black Chokeberry in Korea

다국어 초록 (Multilingual Abstract)

In early June 2014, leaf spot symptoms were observed on black chokeberry (Aronia melanocarpa) inYesan-gun and Geumsan-gun, Chungcheongnam-do in Korea. The initial symptoms on leave surfaceswere brown small-circular spots with a yellow halo lesion, and gradually the small spots were fused,all of infected leaves dropped eventually. A fungus were isolated from the initial lesion, and culturedon potato dextrose agar. Colony color on upper surface of plate varied from olive gray to charcoalgray. Size of conidia mostly extend to 19–50×5–9 μm in nature and 20–59×8–13 μm in culture, with3–8 transverse septa and usually no longitudinal septum or only 1 longitudinal septum in 1–3 ofthe transverse compartments, and also have a short or long beak. Pathogenicity was investigatedusing wounded or unwounded black chokeberry and apple leaves. After 7 days of inoculation,leaf spots were similar to the symptoms naturally occurred in the field. On the basis of mycologicalcharacteristics, pathogenicity, and ITS rDNA sequence analysis, this fungus was identified as Alternariamali. This is the first report of Alternaria leaf spot on black chokeberry caused by A. mali in Korea.
