中文摘要 | 採集自林務局苗圃之臺灣杉葉枯病徵標本,經由病斑組織表面消毒,所分離之菌 株經鑑定計有 Acremonium sp、 Colletotrichum gloeosporioides、 Pestalotiopsis funerea、Phomopsis sp、Phyllosticta sp、Pyrenochaeta sp、Sphaeropsis sp. 等 7 種 。 其中以 P. funerea 分離率較高 (40 % ),C. gloeosporioides 分離率次之 (33 % ) , Phomopsis sp. 分離率為 12.5 %, 其餘菌株分離率較低。 經由接種試驗, 其中 Acremonium sp.、Phyllosticta sp.、Pyrenochaeta sp.、Sphaeropsis sp. 對臺灣杉無病 原性,而 C. gloeosporioides、P. funerea、Phomopsis sp. 對臺灣杉有病原性。 |
英文摘要 | Seven fungal species were isolated from surface-sterilized lesions of leaf blights of Taiwan (Taiwania cryptomerioides) collected from Alishan, Chiayi. These fungi were Acremonium sp., Colletotrichum gloeosporioides, Pestalotiopsis funerea, Phomopsis sp.,Phyllosticta sp.,Pyrenochaeta sp., and Sphaeropsis sp. The isolated frequencies of P. funerea, C. gloeosporioides, Phomopsis sp., Pyrenochaeta sp., Phyllosticta sp., Acremonium sp., and Sphaeropsis sp. were 40%, 33%, 12.5%, 7.3%, 6.3%, 4.2%, and 4.2% respectively. Pathogenicity tests of these fungal species demonstrated that P. funerea, C. gloeosporioides, and Phomopsis sp. were pathogenic to Taiwania. |
