中文摘要 | 1999年9月在臺北縣金山鄉縣政府苗圃進行植物病害調查時,發現楓香的葉部及枝條有大量黑褐色的壞疽病斑。初期葉部病斑呈褐色到黑色小圓點,隨後逐漸擴大並旦相癒合成圓形或不規則形的大病斑,最後全葉枯萎脫落,枝條部位被感染時,頂芽呈黑褐色枯死,枯死部分由頂端向下蔓延。由罹病組織可分離到炭疽病菌(Colletotrichum gloeosporioides (Penz.) Sacc.),經沌化培養後,取其孢子懸浮液回接於楓香的葉片或枝條上,可出現相同的病徵外,亦可由接種的罹病組織再分得炭疽病菌。查閱相關文獻証實楓香炭疽病為臺灣首次病害記錄。 害記錄。 |
英文摘要 | Anthracnose of Liquidambar formosana Hance causedby Colletotrichum gloeosporioides (Penz.) Sacc. was first observed at Chinshan in Taipei in 1999. The fungus had infected leaves and young twigs. The infected leaves initially appeared brown to black, with small round or irregular spots. These spots gradually expanded and fused. Ultimatedly infected leaves died and dropped. Buds of infected young twigs appeared black to blight at first, and gradually the entire young twigs died. The disease was reproduced by inoculation of leaves and twigs with a conidial suspension of the fungus. The pathogen was reisolated from inoculated tissures to complete Koch's postulate. This is the 1st record of C. gloeosporioides on the host L. formosana in Taiwan. |
