Abstract

The aim of this study was to investigate the anatomical characteristics of Quercus mongolica infested by oak wilt disease. To analysis the anatomical characteristics of the wood specimens infested by the oak wilt, the anatomical structures of an infected wood, a dead wood, and sound wood were observed at 10-year-old intervals from 10 to 50 annual rings using both an optical and a scanning electron microscope. The fiber length was measured in units of 5 annual rings from the pith, and the diameter of the vessel element and the ratio of the vessel including the tyloses were measured for each 10 annual ring. In the cross section, on the infected and dead wood specimens, mycelium was also observed with the tyloses in the vessel. There was no signification difference between the wood specimens in the fiber length and the vessel diameter of the vessel element. The fiber length was not difference after 20-30 annual rings which is a part of juvenile wood. The average of the vessel ratio including tyloses in the infected wood was the highest. Especially, the ratio of tyloses was the highest 40-50 annual rings in the infected wood and the dead wood. Therefore, the large difference between the infested wood by oak wilt and the sound wood was the ratio of tyloses. This result can be used as a basic data to utilize the infested wood.

본 연구에서는 참나무시들음병에 감염된 신갈나무의 기초자료를 확보하기 위하여, 해부학적 특징을 비교·분석하고자 하였다. 해부학적 특징을 비교하기 위해, 감염목, 고사목 및 건전재 신갈나무를 수에서부터 10~50번째 연륜까지 10연륜 단위로 광학현미경과 주사전자현미경을 이용하여 관찰하였다. 목섬유 길이는 수에서부터 5연륜 단위로 측정하였고, 도관요소 직경 및 타일로시스를 포함한 도관의 비율은 10연륜별로 측정하였다. 횡단면 관찰 결과, 감염목과 고사목에서는 도관 내강에서 티일로시스와 함께 균사체가 관찰되었다. 목섬유 길이 및 도관요소 직경은 조사목 간 큰 차이를 보이지 않았다. 목섬유 길이는 미숙재 부위인 20~30연륜 이후 안정화되는 경향을 보였다. 타일로시스를 포함한 도관의 평균 비율은 감염목이 가장 높았고 특히, 감염목과 고사목은 40~50연륜에서 타일로시스의 비율이 가장 높았다. 이를 통하여, 참나무시들음병 피해목과 건전재 간에 큰 차이는 타일로시스의 비율로 생각되며, 피해목 이용에 있어 기초자료로 활용 가능할 것이라 사료된다.
