Abstract
This study was investigated and analyzed the side of phenomenological of the chlorophyll bleaching phenomenon on the leaf burning-disease of the Ginseng (Panax ginseng C.A. Meyer) leaf. Red light (660-700 nm) was confirmed as one which induced the bleaching phenomenon and blue light (400-500 nm) did not at all. Temperature as 1 environmental factor had not any influence on chlorophyll bleaching phenomenon at all. Therefore, simple burning (thermal damage) hypothesis was perfectly ruled out by the result of this study. And, low pH accelerated chlorophyll bleaching velocity. A primary factor of chlorophyll bleaching phenomenon may be peculiar structural difference of the Ginseng leaf compared with other plant.
인삼(Panax ginseng C.A. Meyer) 엽소병에 대한 고사원인을 현상학적 측면에서 관찰, 분석한 결과 chlorohphyll의 bleaching현상은 적색광(660~700nm)에서 일어났으며, 청색광(400~500nm)에서는 광산화에 의한 bleaching현상이 일어나지 않았다. 엽소병에 의한 고사원인으로 대두되었던 환경요인 "온도"는 chlorohphyll의 bleaching현상에 전혀 영향을 미치지 않았다. 따라서 단순연소(simple burning)설은 본 실험을 통해 배재되었으며, 낮은 pH는 chlorohphyll의 bleaching속도를 가속화시켜 주었다. 엽소병에서 chlorohphyll의 bleaching현상을 유발시키는 1차적요인은 인삼잎의 독특한 구조적 차이에 의한 것이었다.
