Abstract
This study was conducted to identify fungi causing canker dieback and melanconis disease of walnut trees (Juglans sinensis Dode) in Korea and clarify the pathogenicity and factors affecting the growth of these fungi. The causal fungi isolated from infected walnut stems and branches obtained from the commercial walnut orchards in Cheonwon, Goesan, Youngdong were identified as Botryosphaeria dothidea (Moug, ex Fries) Casati et de Notaris, Phoniopsis albobestita Fairman, Melanconis juglandis (Ellis et Everhart) Graves and their pathogenicity was confirmed by inoculation test. Temperature range for minimum growth of three fungi was 8 to
본(本) 실험(實驗)의 목적(目的)은 천원(天原), 영동(永東), 괴산(塊山)에서 재배(栽培)하고 있는 호두나무(Juglans sinensis Dode)에 가지마름과 고사(枯死)를 일으키는 병원균(病原菌)을 분리(分離)하여 동정(同定)하고 이들 병원균(病原菌)의 병원성(病原性) 및 배양적(培養的) 특성(特性), 발병율(發病率) 등(等)을 조사(調査)하는 것이었다. 분리(分離)된 병원균(病原菌)의 균학적(菌學的) 특성(特性)을 조사(調査)한 결과(結果), 이들균(菌)은 Botryosphaeria dothidea (Mou g. ex Fries) Casati et de Notaris(가지마름병(病)), Phomopsis albobestita Fairman (Phomopsis 가지마름병(病)), Melanconis juglandis (Ellis et Everhart) Graves(검은 돌기 가지마름병(病))로 동정(同定)되었다. 온실내(溫室內)에서 이들균(菌)의 병원성(病原性)을 검정(檢定)한 결과(結果) 2년생(年生) 호도나무 묘목(苗木)에서 병원성(病原性)이 입증(立證)되었다, 균사생육(菌絲生育)에 미치는 온도(溫度)의 영향(影響)을 조사(調査)한 결과(結果) B. dothidea와 P. albobestita는
