초록

춘성 가평 인제 강화 밤나무재배단지에서 채집한 가지나 줄기마름병상에서 11개월균이 분리, 동정되었다. 그중에서 완전세대는 우리나라에서 보고된 Botryosphaeria dothidea(Moug. ex Fries) Ces et de Notaris와 Endothia parasitica(Murrill) P. J. et H. W. Anderson외 Cryptodiaporthe castanea(Tulasne) Wehmeyer, Endothia singularis Shear et Stevens와 Pseudovaseela modonia(Tulasne) Kobayashi등 5개균이며 불완전세대는 Dothiorella castaneae Camera et Vasconcelos, Fusicoccum castaneum Saccardo, Catinula japonica st. nov. Endothiella singularis(H. et. P. Syd.) Shear et St ev. nom seminud, E. parasitico And., nom. seminud와 Coryneum castaneae(Sacc) comb. nov의 6개균이다. Botryosphaeria dothidea는 밤나무줄기썩음병(동부병) Endothia parasitica는 줄기마름병(동고병)을 일으키는 병으로 명명되었으나 이외의 균은 우리나라에서는 밤나무에서 처음으로 분리, 동정되었다.

Eleven fungi were isolated from the cankered stems, branchs and twigs of chestmut trees collected from Chuncheon, Gapyung, Wonseong, Inje and Kanghwa during 1985-1986. Among them, Botryosphaeria dothide (Moug. ex Fries) Ces. et. de Notaris, Cryptodiaporthe castanea (Tulasne) Wehmeyer, Endothia singularis Sheaet Stevens, E. parasitica (Murrill) P. J. et H. W. Anderson and Pseudovasella modonia (Tulasne) Kobayas were identified as perithecial stage. Dathiorella castaneae Camara et Vasconcelos, Fusicoccum castaneun Saccardo, Catinula japanica st. nov., Endothiella singularis (H. et. P. Syd.) Shear et Stev. nom. seminud, E. parasitica And., nom. seminud., and Coryneum castaneae (Sacc.) comb. novo were identified as conidial stage Botryosphaeria dothidea causing canker or diebark but and Endothia parasitica causing Endothia canker were already reported in Korea. The other fungi are first reported in Korea.
