초록
참깨줄기의 반쪽부분(部分)만이 특징적으로 변색(變色)되며 결국은 식물체전체(植物體全體)가 고사(枯死)되는 병미(病微)이 장려품종(奬勵品種)인 광산(廣産)깨와 풍년(豊年)깨가 심겨진 포장(圃場)에서 관찰(觀察)되었다. 병미(病微)은 처음에 줄기의 한쪽 부분(部分)만이 수침상(水浸狀)의 줄무늬(條斑)형태(形態)로 변색(變色)되며, 병징후기(病徵後期)에는 변색부위상(變色部位上)에 황백색(黃白色)
An unusual disease syndrome, partial stem rot and final blight of the whole plants was observed in sesame, Sesamum indicum L., cultivar Pungnyeonkkae and Kwangsankkae grown in the field. Symptoms progressed from water-soaking continuous banding lesions on one side of stem to producing abundant Fusarium growth on the lesion at late stage of pathogenesis. Although wilting of plants was most frequently observed in sesame seedlings when infected with Fusarium oxysporum, reproduction of the partial stem discoloration and rot was possible by soil inoculation, and wound inoculation in old plants. The disease occurred from late July. Mycological characteristics of the isolate Fusarium oxysporum compared with those reported in sesame suggested that the isolate might be F. oxysporum f. sp. sesame.
