Abstract

Mycoplasma-like organisms (MLO) were identified from three plants. The disease symptoms show stunting, yellowing and witche's broom on Cnidium officinale Makino collected from Ulreung Island, Bupleurum falcatum L. collected from Jangsu, and Plantago asiatica L. collected from Daegwanreung. The particles of MLO were observed in the phloem tissues by a Hitachi Hu-11E electron microscope. C. officinale infected with MLO was frequently observed in Ulreung Island.

울릉도에서 채집(採集)한 위축(萎縮), 총생(叢生), 황화(黃化) 증상의 천궁, 전북 장수에서 채집한 위축(萎縮), 황화(黃化) 증상의 시호, 대관령에서 채집한 황화(黃化), 총생(叢生) 증상의 이병주(罹病株)로 부터 전자현미경 관찰 결과 마이코프라스마 병원체(病原體)가 발견(發見) 되었으며 천궁은 울릉도에서 발병률(發病率) 11.9%로써 피해가 심하였다.
