Abstract: 검은점뿌리썩음병의 병원균에 감염된 참외의 광합성 및 생육 반응을 측정한 결과, 수확기 참외의 광합성 속도는 이병주가 건전주에 비해 현저하게 낮았고, 기공저항은 이병주에서 큰 것으로 나타났다. 목부일비액은 이병주에서 전혀 분비되지 않았다. 수확기 참외의 잎과 줄기에서 무기양분함량은 이병주와 건전주 간에 차이를 보여주지 않았다. 참외의 생육특성은 이병주가 건전주에 비해 엽면적이나 생체중및 건물중에서 건전주에 비해 낮았으며, 평균 과중도 같은 경향을 보였다. Monosporascus cannonballus, a soilborne ascomycetes is recently described in Korea that causes root rot/vine decline of cucurbits. The effect of Monosporascus root rot disease on photosynthetic activity and growth was studied on oriental melon plants. At harvest stage, photosynthetic activity of diseased oriental melon plants was lower and stomatal resistance was higher than healthy plants, while xylem exudates were not observed in diseased plants. There was no difference in mineral contents of the leaves and stems between diseased and healthy plants. Leaf area, fresh and dry weights, and fruit weights of the plants were markedly decreased in diseased plants compared to those of healthy plants.
