Abstract
잇꽃 잎점무늬병이 2000년 경북 의성군 일대의 잇꽃재배농가포장에서 발생하였다. 조사지역의 발병엽율은 30% 내외였다. 병징은 발아 후에 떡잎에 갈색의 반점을 만들어 완전히 전개하지 못하여 갈변하여 갈라지는 증상과 생육중기이후 잎에 갈색의 반점과 주위에 노랗게 탈색되는 병징이 생기고 이후 중앙부위는 회색 또는 검은 색으로 확대되면서 주위의 노란 변색부위도 확대되었고, 심해지면 전체가 갈색으로 고사하여 낙엽 되었다. Alternaria alternata의 균학적 특징은 분생자경의 길이는 20~110${\mu}m$; 포자의 크기가 10~20 ${\times}$ 30~60 ${\mu}m$이었으며, 격벽수는 3~8개; beak의 길이는 5~35 ${\mu}m$로 짧은 형태의 포자가 연쇄상으로 붙어 있었다. A.carthami는 분생자경의 길이는 40~80${\mu}m$; 포자의 크기가 10~15 ${\times}$40~100 ${\mu}m$ 이었으며, 격벽수는 4~10개; beak의 길이는 30~65 ${\mu}m$로 대부분의 포자는 하나씩 분리되어 있었다. 잇꽃의 점무늬 병징에서 분리한 병원균의 균학적 특징을 Joseph(1994)의 보고와 비교해본 결과 생육중기에 분리된 균은 A. carthami이었으며, 떡잎과 노쇄한 잎의 병반에서 분리한 병원균은 A. alternata로 동정되었다. 그러므로 이 병을 A. carthami와 A. alternata에 의한 잇꽃의 잎점무늬병으로 명명할 것을 제안한다. Leaf spot diseases were found on safflower (Carthamus thinctorius) leaf in several fields located in Euisong-Gun, Gyengbuk province in Korea. The infected leaf rate of the diseases in surveyed area were different each years from 2001 to 2003 such as about 5%, 10%, and 30%, repectively. The typicla symptoms of diseases appeared first as small, light brown spots on leaves. And then spot turn dark brown and magnified. And yellow decoloration zone appeared surrounding dark brown spots. Mycological characteristics of Alternaria carthami, isolated from safflower mature leaf spot were dark gray colonies, conidiophores simple erect, septated, 40~80 ${\mu}m$ length; conidia solitary, straight, body size fo without beak length 40~100${\mu}m$, 10~15${\mu}m$ thick, Number of transverse septa 4~10 and longitudinal septa 4~7 ; beak with 2~4 septa, 30~65${\mu}m$ length. And A. alternata, isolated from old leaf were gray~dark gray colonies, conidiophores simple or branched, 20~110 ${\mu}m$ length; conidia long chaines, short conical or cylindrical beak, 2~6 transverse septa and several longitudinal septa, body size of without beak length 30~60 ${\mu}m$, 10~20 ${\mu}m$ thick ; beak length 5~35 ${\mu}m$. These are the first report on the leaf spot of safflower caused by Alternaria carthami, A alternata in Korea.
