Abstract
Composition of fungal communities in three microhabitats such as soil, rhizosphere and rhizoplane were studied to understand the root environment of healthy and diseased plants in Phytophthora non-infested and infested fields, respectively. Samples were collected from the tomato- and red pepper-growing greenhouses in Kyungsang-Nam Province on April, 1999. Twenty-five species were isolated from each vegetation field using the dilution plate technique. There were a greater variety of species in infested fields than non-infested and in soils than in both rhizospheres and rhizoplanes. The number of species isolated were varied amongst the different microhabitats. A Trichoderma species was isolated only from non-infested fields.
불건전 토양과 건전 토양의 환경을 이해하기 위해 자연적으로 역병에 감염되거나 감염되지 않은 고추와 토마토 시설재배지의 비근권토양, 근권토양, 근면을 채취하고 연구하였다. 시료는 경상남도의 시설재배지에서 1999년 4월에 채집되었으며, 진균의 분리는 희석평판법을 이용하였다. 각 작물 별 재배지에서 25 종의 진균이 분리되었으며 건전 시료보다는 감염 시료에서, 근권이나 근면토양보다 비근권토양에서 더 많은 수의 종이 분리되었다. 역병이 감염되지 않은 시료에서만 Trichoderma sp.가 분리되었으며 각 작물의 서식지별로 분리된 진균의 수는 다양하였다.
