Abstract
전남지역 수박에 발생하는 바이러스 병의 발생상황을 조사한 결과, 하우스재배의 경우 1998년에 발생이 심하였으나, 2000년 이후에는 노지재배가 하우스 재배보다 발생이 높은 경향이었다. 포장에서 채집한 시료에 대하여 전자현미경으로 128개 시료를 검정한 결과 87.8％에서 막대형 입자 또는 사상형 입자가 관찰되었다. 이들 시료에 대한 RT-PCR 검정결과 5월에는 CGMMV만 발생하였고, 6월 이후에는 CGMMV, WMV 및 ZYMV가 발생하였는데 WMV가 우점하였으며, 어떤 시료에서도 CMV와 PRSV는 검출되지 않았다. Recent occurrence of virus diseases on watermelon plants cultivated in Jeonnam province was investigated from 1998 to 2002. While virus diseases were severely occurred on watermelon cultivated in green house in 1998, those of open field were severer than in green house since 2000. When 128 samples collected from different fields were examined by electron microscopy, 87.8％ of the samples contained rod-shaped or filamentous virus particles. RT-PCR analysis of the samples revealed that Cucumber green mottle mosaic virus (CGMMV) was only detected from collected samples at May. Watermelon mosaic virus (WMV) was most frequently found and CGMMV and Zucchini yellow mosaic virus (ZYMV) were slightly at June and July. However Cucumber mosaic virus (CMV) and Papaya ringspot virus (PRSV) have not been detected.
