Summary: | To investigate the severity of crown gall disease on grapevine, the ratio of healthy vs. galled grapevines and the presence of the pathogen of the disease in soil were measured in Korean vineyards. In field and greenhouse cultivations, the crown gall incidence of the cv. Kyoho grapevines was $0.4{\sim}97.9%$ and $1.4{\sim}3.8%$ and those of cv. Campbell Early was $1.2{\sim}2.1%$ and $0{\sim}1.8%$, respectively. The higher populations of Agrobacterium spp. were isolated from soils of grapeveins with crown gall than from soils of noninfected vineyards. Based on the colony shapes and growth on plates, 480 isolates of Agrobacterium spp. from 21 soil samples were collected. Only 13 isolates out of 480 developed the gall on inoculated grapevines. 한국 포도나무의 뿌리혹병에 의한 발생생태를 조사하기 위하여 뿌리혹병이 발병주율 및 포도나무 재배포장에서 병원균을 측정하였다. 노지와 하우스재배 '거봉'의 뿌리혹병 발병주율은 각각 $0.4{\sim}97.9%$ 및 $1.4{\sim}3.8%$, '캠벨얼리'의 발병주율은 각각 $1.2{\sim}2.1%$ 및 $0{\sim}1.8%$이었다. Agrobacterium 속의 밀도는 뿌리혹병이 발생한 포장의 토양이 뿌리혹병이 발생하지 않은 토양보다 많이 분리되었다. 플레이트상에서 콜로니 형태와 크기로 21개의 포도나무 토양 샘플로부터 Agrobacterium spp. 480균주를 선발하였다. 이들 중 포도나무에 접종하였을 때 13균주만이 뿌리혹을 형성하였다. |
