Zusammenfassung: | Incidence of virus diseases in red pepper of open field in Yeongyang-Gun, Gyeongbuk Province was investigated by reverse transcription-polymerase chain reaction in 2012-2016. The infection rate of Cucumber mosaic virus (CMV), Broad bean wilt virus 2 (BBWV2), Pepper mottle virus, Potato virus Y, Pepper mild mottle virus and Tomato spotted wilt virus was 46.1%, 41.5%, 2.0%, 2.0%, 4.4% and 0.1% respectively. Incidence rate of single and mixed infection was 31.2% and 62.6%. Most of single infections were CMV and BBWV2. Among mixed infections, the incidence rate of CMV+BBWV2 mixed infection was the highest as 49.3% and most of mixed infections of triplex and tetraplex included CMV+BBWV2 mixed infection. CMV single infection caused mosaic, chlorosis, yellowing and vein necrosis and BBWV2 single infection induced cholosis and mosaic. CMV+BBWV2 mixed infection caused severe mosaic with chlorosis or malformation. 경북 영양지역 노지고추 재배지에서 2012년부터 2016년까지 바이러스 증상를 보이는 시료를 채집하여 RT-PCR로 바이러스 감염양상을 조사하였다. 수집된 시료에 감염된 바이러스는 CMV 46.1%, BBWV2 41.5%, PepMoV 2.0%, PVY 2.0%, PMMoV 4.4%, TSWV 0.1%로 CMV와 BBWV2가 영양지역 노지고추에서 우점하는 바이러스로 나타났다. 바이러스 감염형태는 복합감염이 62.6%로 단독감염 31.2% 보다 많았다. 단독감염은 CMV가 19.1%로 가장 많았으며, BBWV2도 11.4%의 발생률을 보였다. 복합감염은 CMV+BBWV2 발생률이 49.3%로 가장 많았으며, 3종 및 4종 복합감염에서도 대부분 CMV+BBWV2를 포함하는 감염형태를 나타내었다. CMV 단독감염에서는 모자이크, 퇴록, 괴저, 황화 병징을 보였으며 BBWV2 단독감염은 퇴록, 모자이크 병징을 나타내었다. CMV와 BBWV2 복합감염은 퇴록과 심한 모자이크, 기형 병징을 일으켰다. |
