摘要

為了釐清長喙殼菌(Ophiostoma querci (Georgevitch) Nannf.)對杉木(Cunninghamia lanceolata (Lamb.) Hook. var. lanceolata)以及其他針葉樹種是否具致病性，以中興大學植病所黃振文教授提供之長喙殼菌菌株(0PH106、OPH110、0PH15K)進行對杉木、台灣杉、紅檜、五葉松、香杉以及肖楠等6種2年生針葉樹袋苗之致病性研究。以10^(5-6)spore/mL長喙殼菌孢子懸浮液2ml接種樹苗後每日觀察是否有產生病徵，5個月後發現以3個菌株接種之針葉樹苗都和對照組一樣並未發現有任何病徵。以OPH110菌株孢子懸浮液10mL(10^(5-6)spore/mL)接種和社地區20年生造林地福州杉及OPH106菌株孢子懸浮液10mL(10^(5-6)spore/mL)接種九族文化村地區20年生造林地福州杉，接種後每2週觀察是否有產生病徵。經5個月的觀察，發現以OPH110、OPH106菌株接種之杉木跟對照組一樣並未發現有任何病徵。

To clarify the pathogenicity of Ophiostoma querci to Chinese Fir and other coniferseedlings,2ml spore suspension (10^(5-6)spore/mL) of three isolates of Ophiostoma querci (OPH106、OPH110 and OPH15K) from Professor Jeng-Wen Hung of National Chu-Hsing University were inoculated on two-year-old seedlings of Chinese Fir (Cunninghamia lanceolata Hook), Taiwania (Taiwania cryptomerioides Hay.), Taiwan Red Cypress (Chamaecyparis formosensis Matsum.), Taiwan White Pine (Pinus morrisonicola Hay.), Luanta Fir(Cunninghamia konishii Hay.),and Taiwan In-cense-cedar (Heyderia formosana H.L.) Daily examinations for five months found no symptom on both the inoculated and controlled seedlings of all the six conifer species. In addition,20-year-oldChinese Fir trees in Ho-she afforestation land were inoculated with 10ml spore suspension of OPH110(10^(5-6)spore/mL) and in Formosan Aboriginal Culture Village afforestation land with OPH106 isolates. Bi-weekly investigations for five months observed no symptom on both the inoculated and controlled Chinese Fir trees.
