Abstract
본 논문은 선충 포식성 곰팡이에 대한 선충의 영향을 조사한 연구로, 소나무 기생곰팡이인 E. vermicola에 미치는 소나무 선충의 영향을 체계적으로 분석하였다. 선충 대사물과 선충 균질액 모두 E. vermicola의 성장을 빠르게 촉진하였으나, 선충 대사물이 선충 균질액보다 약간 높은 효과를 보였다. 또한 소나무 선충이 생성하는 휘발성 물질이 E. vermicola 성장에 미치는 영향을 분석하는 새로운 실험방법을 개발하였다. 본 연구결과에 따르면, 선충의 휘발성 물질은 E. vermicola에 아무런 영향을 끼치지 않는다는 재현성 있는 결과를 도출하였다. 본 연구는 소나무 선충의 생물학적인 조절인자로서 E. vermicola을 적용할 수 있는 정보를 제공할 수 있을 것이다. The influence of nematodes on nematophagous fungi has seldom been investigated. In the present study, the influence of pinewood nematode on its endoparasitic fungus, Esteya vermicola, was investigated systemically. Although both nematodal metabolite and nematodal homogenate could stimulate and speed up the growth of E. vermicola, the impact of nematodal metabolite was slightly higher than that of nematodal homogenate. In addition, a method was developed to investigate the influence of volatiles, discharged by pinewood nematodes in their metabolic process, on the growth of E. vermicola. Reproductive results were given and confirmed that nematodal volatiles have no influence on the cell growth of E. vermicola. This study may provide information for the application of E. vermicola as biological control agent of pinewood nematode.
