Abstract

The pathogenesity of 25 isolates of Colletotrichum gloeosporioides from apple, 42 isolates from pepper, 5 isolates from jujube, 8 isolates from persimmon was evaluated to know transmission to strawberry from other infected plants. Followings are the results. Colony morphology and spore size on potato dextrose agar was similar. When each isolate was inoculated on leaf and petiole of strawberry, isolates from persimmon was the most pathogenic. Five isolates, one pathogenic isolate per each host, were evaluated in simulated field condition under natural rainfall for their natural infectivity. All isolates infected strawberry in field condition, so C. gloeosporioides from other hosts are potential inoculum source of strawberry anthracnose.

다른 기주에 발생하는 탄저병(C. gloeosporioides)이 딸기에 전염되는지를 알아보기 위해 사과, 고추, 대추, 감의 이병된 과실에서 탄저병균을 분리동정하고 딸기에서의 병원성을 비교하였다. 각 기주별로 분리된 C. gloeosporioides의 배양적 특성과 포자의 크기는 서로 유사하였으나 말기에 접종을 하였을 경우에는 감에서 분리된 균주가 병원성이 가장 강하였고, 대추에서 분리된 균주는 약한 병원성을 보였다. 각 기주별로 병원성을 나타내는 균주를 선발하여 포장에서 병원성을 검정하였을 때 모두 탄저병이 발병되었으므로 다른 기주에서 발생한 탄저병도 자연상태에서 딸기로 전염이 가능한 것을 확인할 수 있었다.
